A couple days ago i started noticing that after about 10 mins of driving the car loses power from 3k-5k rpm. The rpm increases but the speed doesnt increase like it used to and it seems like the car is choking. I have a severe OC problem too. Anybody know what it could be?

 

Could be a lot of things, 1 is it very very hot out? could be the throttle body also does it rev normally before that mark? Your temperature is fine? I see you have a spacer too make sure your bolts are torqued down or once the manifold heats up it could be leaking

 

Is it hasnt been too hot. The car runs normal before it hits 3k rpms. Temp is fine. I dont have the spacer anymore.

 

I noticed that when im driving normally the car runs fine. The minute i start driving aggressive in manual mode or drive the car starts acting funny. It doesnt pull like it used to after 3k rpms. The car hesitates.

 

slipping clutch? I dont know anything but I think thats what happens when you have that :O

google it to find out more info

 

i have an automatic though

 

ok well I searched google for you for a sec even though maybe you should of.

any how Automatics do have clutches but the slip might happen during shifts. Does it slip when it shifts or only when just accelerating in gear?

 

I searched google but i didnt get a chance to post.

It feels like its slipping after i shift the gear and it continues to slip until i change gears. 3rd gear feels the worst though. The car will not pull like it did in that gear. Im still under powertrain warranty so ill have Infiniti check it out.

 

oh yea something to do with your transmission I guess if its slipping when changing gears and such. Google "Automatic Transmission slipping" I guess you can find more info that way. But yea defiantly take it in asap.

 

cool, thanks man

 

could old transmission fluid be causing this problem?
