Car Forum / Nissan / Nissan Maxima / September 200496 Maxima SE car sputters at 2000 rpm
Car starts fine, idols fine, and runs fine EXCEPT when I drive over 2000 rpm's. If I accelerate slowly all is ok until I reach 60+ mph (2000 rpm). If I accelerate quickly it shifts gears until I hit 2000 rpm's. Both cases the car sputters and I have to decelerate. I thinking it is the fuel pump, but again the problem is only at 2000 rpm. Any ideas? Seems I have heard that could be the mass airflow sensor.

But a failing MAF sensor might be different. Any CEL codes? Dave > Seems I have heard that could be the mass airflow sensor.

CD Yes, they light up when I'm starting the car, but they go off as normal Try replacing the pressurized gas cap. Get the correct one - mine said "pre-vented." Made my 92 SE stop all that rough running immediately.

I filled up with gas and left the gas cap off. I rode about two miles and noticed the open gas compartment door. I pulled over and put the gas cap on while the car was running. I now still have the vaccum sound when I open the gas cap, but car still sputters at 2000 rpm's and car will not go over 60 mph. I have no warning lights and I still get 400 miles on a tank of gas (not leaking gas. Any other idea's? |
