hummmm

on my way to the Meet today all of a sudden my car cut out...the rpm's would go over 2000. felt like it was hitting the rev limiter. Im sure its not a mechanical prob cause later it worked again. Somehow the ECU is cutting out around 2000rpm. Possible cam or crank sensors would be my guess. I pulled the codes at home and its the same O2 sensor and EGR codes ive had forever. whats going on? i swear the car is cursed....this sucks.

 

That sounds like limp mode, only thing is I don't think 95's have limp mode, hmm.. Ahh, I have no clue what could cause that, how about "false air" after the intake, I think that would make your car idle real high and act strange. Check for air leaks. If the problem is intermetent it's probably something electrica though.

 

I would say the MAF needs to be looked at. In my maxima and se-r if I was to unplug the MAF the engine wouldn't rev over 2000rpm, nor would it idle. Try unplugging the maf to see if the same conditions happen if so then you've found part of the problem.

 

you need a new turbo.

 

a bigger one at that.

 

i can't beleive you can run into so many problems for a simple/impossibly accomplishable turbo kit. I have been reading up on your maxima's history for the past couple of years and i am still astonished that its not 100% yet.

 

And some of you guys are hoping for a trouble free turbo kit.

 

maybe its the people making "THAT" kit and not the kit per say

 

I hope the kits do come through though (I might even switch over ).

We'll see an influx of "Blown tranny", "Slipping clutch", and "Blown motor" threads because of all the greedy boost ******.

 

their are successful Turbo Max's running around

check the NE Forum

 

Yeah, I read that thread (but haven't been keeping up with it).

You guys know his stats yet?

 

no but if Hogan is only 1 car slower than him.. he must be running like -10 PSI

 

hummmm...sucks...at least Lynn's car is here and i can steal i mean borrow parts off of it temporarily. here we go again....ugghh

 

Hmmm I remember when I blew some of my pressure side hoses off. It ran similar to what you describe. Check and reclamp all your hoses. Boost leaks are a major pain. Then again, swap mafs and see if that cures it.

 

i dunno...it doesnt seem like its a mechanical type prob. Ive had pressure side hoses come off before and it didnt do what its doing rite now. Its like the ECU is keeping the car from revving higher...caused from what i dunno.

 

Boy, that surely sucks... Perhaps you should look into an Infiniti qx4. I heard that solves a lot of problems as far as maximas not working... hmmm....

 

Hey Matthel,

Sounds like the limp mode alright, but if I remember, limp mode prevents the engine from revving over 3000RPM, not 2000. I don't have it with me now, but check the FSM to see what would cause the ECU to go into limp mode. Several off the top of my head include excessive wheel spin (for automatics), overheating, and multiple engine misfires (deterioration of exhaust quality).

BTW, replaced my LH O2 sensor this past weekend. Mileage back up again! Before, I got 14MPG on the highway with the bad O2 sensor.

 

Go away... we don't talk to supercharged QX4's.

 

SC QX4 .. whta does that run? mid 15's?

 

Let's not talk about his dyno.

 

thanks Eric
ill look into it. Jeff metioned that he remembered one of the codes we reset while on the side of the road. it was the crank position sensor. Since Lynns car is here im gonna borrow his and see wassup.

 

try getting a new ECU......the g-force maybe?

 

he has boost.. its not as easy as going to pick one up from the store..

 

Hahaha, seriously... I'll get it fixed soon enough...

 

Riiiiiiiiiight. Get a BOV installed while you're at it.

 

Matthel, same thing happened to me. I would have said something at the meet, but the correlation didnt click in my head until now. Of course I dont have a turbo, but I when i was messing with my g-force ecu it happened. I would bet 100 bucks that your TPS(throttle position sensor) is busted. I paid like 100 and something for mine from the dealer and after I got it installed, the car worked perfectly. Mine would not go over 2000 either, so i bet you have the same problem. You could run the ECU trouble codes and see if thats really the problem I think.

hummmm sounds interesting...ill check it out. thanks James

i did get TPS sensor before but not recently. but my car is so messed ive basically had every single trouble code imaginable.

 

hummmmm

so turns out the bolt holding the crank sensor actually broke. so we're thinkin yea we found the prob, extract the old bolt and check the crank sensor, its ok, so we put it back in and still same prob....crap.

 

crank sensors suck. i had prob with mine before i sold my 95.

 

i heard MattC wants to such you
