maxima makes no power
maxima makes no power
i got a 97 maxima 3.5 with bolt ons. one day the car just stop running right and aquiered a waste gate and the car wouldnt pull hard. car runs smooth just makes no power. the waste gate issue was due to 2 blown exhaust gaskets coming down from header going down to the y-pipe. those where replaced and no more waste gate but still no power. i have a cel but only for rear o2 sensor. which wouldnt cause a loss of power. i have changed just about every sensor in the motor still no good. i felt like its gotten faster but not 100 % to full potential. the car wouldnt catch traction till 3rd b4 the incident and ever since it broke it wont even break them loose so there is a prob some where. i use to put cars on my friend with a 5.5 gen with bolt ons and now hes putting the cars on me and he hasnt done anything since the lasttime we ran. i feel like the car is good off the line till about 3rd then it dies down idk why. sorry if this is a lil long but idk wat to do anymore i have done everything possible. and im stumpped so if any could lead me to some assistance if would be greatly appreciated thanks

you want to feel that it is week because you want the car to be in top shape.
if you have a full 3.5 with ecu, and boltons with a 5 spd, and u claim that u changed all sensors "including knock sensor"
then i doubt there is anyproblem with the car. jusy dyno it and see what happens

Unbolt your knock sensor and bolt it to the negative terminal of the battery, it sounds like it's pulling timing, possibly related to a: an exhaust rattle that is new after you swapped the manifold gaskets or B: it's related to why the gaskets blew out, but my geuss would be A. If grounding the KS doesn't do anything, I would check for a plugged cat or muffler.
FYI, for future reference so you don't get schooled on here: if you are asking a question about a 3.5 swap car, put it in the all-motor section, but only AFTER you have read the stickies so you don't come across like an idiot. And it would be helpful if you put your fuel pressure in the post as well, since many are running 51psi still which is so far from the ideal of around 32-34psi.
Oh, and a "waste gate" is not the proper term for an exhaust leak, a wastegate is a valve on a turbocharger that lets exhaust gasses bypass the turbine

sorry if offtopic: ive been hearing a lot about this KS grounding issue, i almost feel like i should reground mine just for the heck of it also. can u ground it as in tapping the harness and running another wire to the battery negative or does that require actually bolting the KS to a ground?
I agree with the KS. When the ecu off the 4th gen pulls timing its like hitting a brick wall. since the a32 ecu already has crappy timing its even worse when your running a 3.5.
Possible that your ks it self is bad as well. But i would try to ground it to the battery post like stated previously. Or you can pick up the 470k resistor at radio shack for 99 cents. Imo grounding it to the fender or whatever is equivlent to having a resistor
There is a thread about this whole setup in the AM section.

Hey Jayson, If your going to Reply, at least keep it relavent to the Topic At Hand.
To the OP. You mentioned you have an 02 Code, Which Bank. If its on the Mani, than it can really screw with your Gas Mileage and your performace to some level. First off, Have you tried clearing the Codes? Also you mentioned Bolt ons and such? Im assumeing these are All Exhaust Related?

For starters: you expect help without much information at all? Hybrid swap? Complete?
You're really relying on breaking traction to determine power level?
This 5.5 you've been racing, it is at the track, correct? I'd hope so, otherwise you're just asking for a ban.
You say you just have bolt ons, then you mention you just got a new wastegate?
Did you do anything to the car, have anything done, or did anything happen prior to this power loss?
Are you tuned at all, or running off of the stock ECU with nothing else (whether it be 3.0 or 3.5)?
Are there any signs of it running extremely rich? Massive fuel consumption, black smoke, etc?
I don't understand how one could even confuse those two...

All Motor forum, 5.5 gen forum... You didn't even post what year your engine is, if you got it from a 6th gen or 5.5 or which car you got it from, I'm not saying you're just SOL by posting in the 4g, it's just that you'd have more people with your engine looking at your thread, instead of most of of us 3.0L guys...
+1, not to say your butt dyno is out of wack or anything, but a dyno along w/ some A/F ratios will help the experts out allot.

ill keep those forums in mind..i got a 02 max motor...as far as being dynoed car was dynoed last year made alright #s but could have been better if the tune was better.. runing a lil rich

i grounded out the ks already to the battery did nothing.. i even used a resistor and still nothing car was the same. as far as a cat i dont have 1and i will look for plugged passage way in the exhaust.
thanks i will deff post in the all motor sec next time...as far as fp goes idk what it is but i will find out..
i used the term waste gate b/c thats wat it sounded like. didnt sound like a exhaust leak

Damn, that was one huge block of text. Sentence structure, paragraphs, etc. The more readable your post is, the more people will want to help you.

So by wastegate he meant an exhaust leak?

yah the track howd u kno ... and yes i got bolt ons and wen i meant waste gate when the car broke it all of a sudden had a waste gate sound to it so something wen wrong.
i didnt really do anything crazy b4 it happend i adjusted the crank sen on the tranny but i ran the car after that it was good then the 2nd time i hit 3rd and something didnt feel rite and it didnt go anywhere and since then its been no good on power
yah runs a lil rich some black some a lil bit gas hungry
!!!!I beg to differ that the oxy sensor isn't making a difference. If you are running lean or rich you'll notice a drop in power.
As for this 'wastegate' ... anyone remember the member with the 'dump valves' on his exahust! ROFL ....
Oh, it's so sad ... yet so much fun!

Or could it?
That O2 monitors the cat efficiency.
You could have a clogged cat, which may have been why you were blowing exhaust gaskets in the first place. That will def. cause a loss of power too.
Holy crap. How many posts you going to post?? lol
Might want to look at that again. A bad or mislocated ckps will give you a world of misfires bad ignition ect ect.
Also what resistor did you use?? Did it say 470k on it?? How did you use it?
@ wastegate. I was thinking how can you just have bolt-ons and have a wastegate lol

This is going to sound crazy, but is it SERIOUSLY down on power, I mean like down A LOT? Any metalic sounds coming from the engine? And hows the oil and other fluids check out?
To the OP:
Why did you mess with the CKPS? Not saying that is it, could be multiple things at this point still. Do you have an aftermarket exahust, or is it still stock? Also, how many miles on the car (both the car and the 3.5)?

yes i used the 470k resistor i put each end threw each hole on the ks plug and then taped it up.. i think the ckps is in the right spot b/c only from there will it start perfect and i dont have any misfires

yes it is really really down on power like big time...no metallic sounds coming from the engine.. oil is good i always do my oil changes at 3k all other fluids are good. idk wat to do anymore ive tryed everything
Kev - whatchya thinkin? That's a good idea though, check the fluids.

As far as thrashing goes I love my car and always maintain it well. I have my funn .. but it seems like its tired ..runs smooth tho

well the proof is here...its official the max is not making any power got dynoed this morning and the resutls where horrible...
1st run 185.95hp 181.01tq temp:86.57 F humidty 29%
2nd run 191.03 hp 180.24tq temp 89.39 29%
3rd run 189.36hp 181.92tq temp 88.57 28%
last time i got dynoed which was about a yr ago i made 240hp and 220 tq in about same temp 90 F obviously there is something wrong but i dont know what b/c the car runs fine and smooth but theres no power to it.. im thinking it could be in limp mode but idk wat could be causeing it.... feedback is needed

damn....you werent joking. anyways, youve changed every sensor, including the KS 3 times. have you checked out the KS harness? it really sounds like a KS issue. Maybe it melted or something, test it out.

A few notes worth mentioning:
limp mode is only on auto trans (I'm pretty sure anyway)
reason I ask about body (really - exahust) and engine was to see if there might be something there, doesn't seem to be. Have you tried to reset the ECU? Unplugg the bat terminals (both of them) and tie, literaly, them together - leave it like this for 15 min's or so, then hook it back up. You're using the stock 3.0 ECU, correct? Have you got access to a 3.5 ECU by chance? If not, try and pick one up in the classifieds (5.5 or 6th gen) for cheap, could very well be your problem.
You were 'adjusting' (although, there really is none) the CKPS, anything else? Make sure your MAF plug is on all the way and that nothing is in the way blocking it (the wire inside). CAI, or stock intake? Does the car seem to rev ok in N, or does it seem to dog even then?
WOW !!!!! That's sad, really sad.

the 3.5 ecu isnt plug n play with the 4th gen harness. Using the 5th gen ecu would require quite a bit to make it work. If that was the case no one would be doing a hybrid swap into a 4th gen.
