2003 350z touring 6mt

Im putting my car back to stock. i had a built motor (which im selling) and the hks tt kit. I just installed a stock motor (i installed my built motor myself too) and cranked the car.. it starts and idles fine (1000rmp) but it wont rev past 2700 rmps while in neutral and car is in jacks... it also hesitates to rev period and car shakes a lil more than usual.. i know it could be anything but i am open to suggestions!!! i need to get my car running by tomorrow!!!

I am reading anything that has to do with limp mode.. i will also check and recheck all connections.. which i made sure to check and recheck b4 i starter the car.


anything else?

 

i replaced the throttle body with a spare one i had.. still in limp mode.

 

You need to pull codes and troubleshoot from there. Do you have access to UpRev's Cipher or other method of examining data from the ECM?

 

yea.. i knew this was coming. i will get a obd2 reader from my buddy tomrrow. but im sure i will get at least 10 codes lol.. all my lights come on when the car starts!!!

 

What the hell is that trigger on the flywheel? My bets

 

plz explain ...

 

You sure you have the firing order right thats what it sounds like

 

I am having the same problem. I haven't pulled codes yet. If you figure out what the problem is please post as well as your solution. Thanks.

 

Ok now i can post again, the Trigger or sensor on the back of the flywheel is probably doing that.

 

yes... i think this might be the prob.. tell me more.. can this be installed the wrong way or does it just go bad?

 

Never had to do mine, but i know its something to do with the clock position or something. Search under flywheel intall how too, see what comes up for you.

 

pulled the code.

only one came up with the key on the on position, but the car was not on.. (couldnt turn it on)

p0340
Cam position sensor
A Bank 1 ckt
malfunction

which side is A bank? i have spare cp sensors...

 

ok. so bank 1 is pass side. i swapped cam sensors and still same code comes up. i will swap the other side tomorrow and see if that one is the problem.

would the crank sensor b a different code?

 

anyone can help???

 

What clutch and flywheel is on that stock motor now?

 

stock clutch and fly

 

Crank sensor, maf saensor. DOUBLE check ALL your connections, I'm betting you forgot to plug onw in. Maybe the one on the TB??

 

everything is connected.. but im not sure if maybe i have a bad sensor.. and the only code i got was the cam positioning sensor.. which i replaced but the same code comes back on.

 

Are you sure you lined up the flywheel properly when you installed it. There is a small dowel on the crank that has to align with the a small hole on the flywheel. But if the little dowel is missing from the crank it could easily be misaligned. There is a crank position sensor on the drivers side of the trans, it is between where the trans bolts to the block. It looks like a cam sensor. Make sure this sensor is good, try to replace it with one that works to make sure that is not the issue. Do you recall aligning that small little dowel when you put all the flywheel bolts on?

 

flywheel was aligned. but i will replace that sensor..
