Ok i went out and started my maxima this morning and it was idleing higher then normal and everytime i put it in drive or reverse it would shake and shut off. this happen to anyone else?? and ideas??

 

vacuum leak.

 

check the maf as well!

 

well ive been lookin all over to figure out whats wrong with it idk where the vacuum leak would be. this is driving me nuts. idk why a vacuum leak would kill my car. my maf is fine i have no check engine light on either.

 

what about your TPS

 

MAF sensor plugged in? killed mine for a while until I figured that one out.

 

Whats TPS?? And yes the MAF is plugged in. It only does it when its cold out. When its hot it dont. Or if i let it sit long enough for it to get cold. Ugh really not likin my max right now.... Now my trans is messing up to the over drive is sputtering when i let go of the gass about 40 to 60mph......

 

I had a similar problem and it mostly went away when I got a tranny flush. Drives a little better now. Also, maximas just do that kind of thing, dont let go of the pedal so quick, be real easy on it once you feel right where it starts giving gas.

Also, motor mounts could be going bad.

TPS is throttle position sensor.

I also have a similar problem with the rumble at idle.

 

Sure it's not your IAC *Idle Air Control* valve?

 

IT is a maf or a Vacuum leak.

 

IAT or ECTS. 25 bucks each.

could be TPS too.

U clean TB, MAF, IACV, and grounds?

 

ok well i got my tranny flushed and that fixed that problem and the cold start problem is still persisting i have a check engine light on and it says egr but i put a brand new one on and got it erased and it came back on. and its still doin the same thing so i guess ill go buy the TPS tomorrow and see about cleaning an maybe replacing the IAC. HOPEFULLY everything will work out lol
