Hey everyone first time posting here and thought maybe you guys could help me out. I have a 2004 maxima and just the other night I started the car and while warming up it shut off. I turned it back on and it was slower than normal to start. On my drive home the car had no acceleration. I would be pressing down on the gas pedal and it would take forever to build up speed. Driving up my hill was nearly impossible as I gave it as much gas as I could and it was barely going 10 mph. Any help would be greatly appreciated. Thanks

 

just need a little more info here, was the engine stalling or hesitating? or there was engine power but wasn't pushing the car?

 

Hook up your car to an OBD scan tool and look for error code. Might be the throttle assembly, MAF

 

Colt149 is correct. It could be those durn CAMSHAFT Sensors and CRANKSHAFT Sensor also.

 

I have an 04 Nissan Maxima that i just replaced both camshaft sensors due to SES light was on throwing a code for bank2 (figured replace both while doing it). I left my battery disconnected for 24hrs which cleared the SES. It took longer then normal to start but idled fine. Put in reverse and had good acceleration but when i put in drive it had very poor response (like limp mode). I got it on the hwy up to 80 mph and never acted like it was going to shut off or die. The only problem is it will just not accelerate like it should. Any suggestions?? Thanks

 

Read the codes!
