Recently I'm having problem with MAF sensor, Chinanitrous and other members told me to take it out and clean it, cuz I can't rev pass 4500rpm. I just cleaned it like 10 mins ago, I went out to test it out, now whenever i reach 2500rpm my car just keep on jerking back & forth and it wont go over 2500rpm. HELP, someone in the house is about to kill me

 

Just trying to rational here. Why not just have the car towed to the dealership and make them fix it under warranty? your car looks like a 2k2 so it's gotta still be covered. Too bad Nissan doesn't have roadside assist or has that changed? Don't worry, it'll work out. Just be calm and good luck.

 

cuz I have frankencar intake & i lost some of my screws for stock intake, so i can't put it back on there yet. Can someone tell me DaveB's number? I need to order some screws

 

When you cant rev past 2500 I think that means the maf is gone, dead no longer functioning in the correct manner.

 

Then have Frankencar send a new/remanuf MAF. They stand behind their stuff, right?

 

What is the difference between the Frankencar MAF and the Nissan MAF.

 

Frankencar, Frank Fontaine, Frank Sinatra, no difference. But we're talking about a 2k2 Max with a MAF that failed. Maybe the intake caused it, ya think?

That's why a product is only as good as the co. behind it. 20-yr warranty on a roof but the the dude with the pants that don't cover his **s crack ain't gonna be around in 20 yrs....what good is the warranty?

What did you clean your MAFS with?

 

k&n air intake cleaner

 

Sorry but frankencar did not make a MAF..this is simply an intake that replaces the factory airbox and factory piping. The maf system is just in between the frankencar pipe..and K&N filter... His problems started originally with over-oiling the K&N filter. I too had the same problem. The reason why he cannot rev-over 2500 is beacuse he actually unplugged it..and accidnetally started the car. THis causes a open circuit in the system...the nissan ECU records this..throws a service engine soon light....and limits the rpm to 2500. He simply needs to go to the dealer with his stock intake on. I admit i had the exact same problem...over-oiled...cleaned it a little bit with intake cleaner...got the car to rev to redline..but it felt like it was struggling. Cleaned it again...PERFECT. But when i went to the runs...the light came back on...so Im defintaly going back to nissan while i have my stock intake on. So..be carefull with the intake oil. Seems like NIssan MAFS are especially sensitive.

 

This may seem simple, but I didn't see it mentioned in any of the posts. Have you tried resetting the ECM? The FSM says to do that after any repairs are made. Since the MAF was unplugged, car started, it's stored a DTC. Now with the old MAF plugged back in, if the ECM is reset, it will believe it is a new MAF, unless of course it is truly faulty and it wasn't just dirty. I'd reset the ECM doing the clockwise/counterclockwise thing with the screw, or you can simply disconnect the negative battery terminal for up to 24 hours. Keep in mind that the car may run like crap for a little bit as it relearns all of its necessary settings for everything.

i was soo thinking about that...but...id rather have nissan replace it..since my MAF has been pretty banged up with the red puddle of oil on my Air filter adapter...

 

According to my FSM, the ECM is going to have the "freeze frame data" stored (6+ items). According to the FSM "Description for Work Flow", pg EC-77, they are to "Check and write down (print out using CONSULT or Generic Scan Tool) the DTC and the (1st trip)freeze frame data, then erase the code and the data. The (1st trip) DTC and the (1st trip) freeze frame data can be used when duplicating the incident at STEP III & IV". Nissan may wonder what was going on, especially since they will extract the data, then reset the ECM, and check it again. Should be clear the second time. This will tell them someone was messing around, and who knows if they'll charge for diagnostics. I'd reset it just to get rid of the 6+ emission-related diagnostic information from the ECM and ECM backup memory. If you have an FSM handy, the pages I'm looking at for that are EC-51 and EC-53. If not and you need more info, email me or post here and I can email some scans for you.

oh dear....im so confused..haha...I understand most of what you said...except.whats an FSM?..ugh..im so slow at these things...i guess i'll search a bit...and see if i can understand everything. I hope for Biomax's case..they wont charge me..cuz they knew someone messed with my MAF..but they cleare dhte codes anyway..and sent me on my way. But...hmm i know when the check engine light is solid...its just kinda idle...but mine blinks every so often..does that mean a new code is being thrown?

 

FSM=Factory Service Manual (mine's for a '97, but should be the same when it comes to basics about ECM. Anyone correct me if I'm wrong, 'cause I'm not 100% on that.) If yours blinks every so often, I'm not sure. I'd check codes, then clear them. Then I'd leave them alone for a few days and check again. I did see a pamphlet at a dealership about blinking MIL meaning either emissions problem or a serious mechanical problem and steady on MIL meaning the opposite of blinking. But I can't remember which goes to which. One you could still drive, the other it wasn't advised to.
Whether or not the dealership will charge diagnostics if they suspect tampering is up to the dealership. I've heard horror stories about some dealerships on here, but praise for others. Luckily the 2 in my area are very good. Also luckily I don't need them often, except once for AC warranty work on my '96 GXE (RIP) and now for maintenance parts on my '97 SE.

update

I disconnected my battery last night. This morning I was able to start my car and everything 'felt' fine until I shift to drive, the car would just jerk a lil bit & dies again....................

 

I had a blown MAF....EXACT same problems your having. I used throttle body cleaner...all that stuff. NOTHING will help it if the MAF is actually blown.

The "hot" wire in mine was NOT broken either, everything looked in tact.

PM me if you want experienced advice.

I put a Frankencar intake in which I think hauls butt, but the SES keeps coming on. I can rev to redline no problem, and the car runs great. Do you think I should clear it several times 6x as suggested? Will that erase everything from the ECU? I guess if it keeps up, I may put the stock one back on and see if it repeats the SES. Any suggestions?

 

there are recalls on the 2k2, see the 5th gen forums.

the MAF's on 2k2's also suck, see the 5th gen forums.

 

So....you're......trying......to......say.......se arch.....or.....at.....least.....look.....in.....t he......5th.....gen......forums.......Don't.....yo u.....realize.....that.....requires.....effort.... .even....though.....it.....will....alleviate....hi s....concerns.....and......probably....expedite... ..solving....the.....problem?

 

Your big mistake was cleaning it with anything other than an electronics cleaning agent. either methyl alcohol or electronics cleaner should only be used.

the sensor itself is a very sensitive part, and any nasty cleaning chemicals other than stuff designed to clean electronics will likely eat it up and ruin it. wouldn't surprise me if the MAFS is now dead.

alcohol is a "soft" enough chemical that it won't corrode the metal, but the K&N filter cleaner and TB cleaner and other stuff like that are all very harsh chemicals which could possibly ruin it.


Let's hope for your case that they don't catch on and make you pay for a new one.

 

Bill...something like that...but I gotta be nice!

 

Hello Bill.

 

 

You can get bolts and nuts at any hardware store to reinstall your factory intake....then, if the dealership trys to blame it on you, just play dumb and say that they were the last ones to work on your car...I did that and got a new tranny after my warantee ran out, and I had a stage III clutch/aluminum flywheel, coilovers, y-pipe...etc.

 

Nissan does roadside assistance so just call 1 800 nissan1, and they will give you the number to roadside assistance free of charge!!!

 

"Frankencar Performance assumes no liability for damages to the vehicle that our intake systems are installed on."

 

Didn't stillen pretty much have the same attitude?

Be logical, somebody spends more than 20k on a brand-new car. They use a mod and a very expensive device fails. Might be better business sense to make things right.

That kinda liability stuff reminds me of telecoms, where it's always his fault (fingers pointing at each other). So where's the DMARC? Where this franken thing meets the MAF huh? Bah

 

1. we can not control how the customer treats the MAF when installing the intake, ie if they drop it they could try to blame it on us.

2. all aftermarket manufacturer's have this stance with intakes as far as i know.

3. in this case the car wouldn't rev above 4500rpms which could be a sign of a VIAS malfunction not a bad maf.

4. the maf was cleaned with an agent that would cause most any maf in any situation to malfunction.

5. a customer could over oil their filter (not under our control) and cause an MAF to fail, again not our fault.

6. there is a TSB out for MAF's and the 2k2's are known for having faulty MAF's.

all and all there are too many variable and fingers to point, the best thing to do is take it back to nissan with the stock intake on and have them fix it as that is where the problem seems to stem from.
