Check EGR valve and sensor it might be carbon up or stuck and the sensor might be bad.
EGR valve and sensor connected to it control idle at start up.

Why does my 1995 nissan pick up lose power and speed on uphill inclines?


If you keep the RPMS (tach) up to 3000 and above (DONT REDLINE YOU'LL BLOW YER MOTOR UP!) At 3000 RPM to 3500 -4000 RPM is where these motors posses what i figure is a power band that handles most inclines. Down shifting included. DRIVE SAFE

2000 pontiac grand am 3.4 motor auto trans 4 door.Car starts and drives okay motor seems to stumble slightly between 3000-4000 rpms. with car stopped in park try to rev motor will only go between 3200-4000...


Hi Tom your vehicle is equipped with a Rev limiter it will not allow you to rev the engine above 4000 with the trans in park; as for the first problem you may have one of two things, one of the spark plugs or spark plug wires is bad or you have a flat spot on the throttle positioning sensor in which case have be replaced. Good luck?

Dash cluster (speed and tach) do not reset and give false reading. Start and tach could say 4000 rpm's and speed at 80 mph in park.


Hello: You have a bad cluster. The only way to repair is to replace the cluster. It will also have to be programmed after replacement. The cluster was a high failure rate item from 2003 t0 2005.

The voltage regulator is a part of the alternator.If you are having pulsating issues then look for grounding issues like a corrided eyelet or loose grounding bolts.

Transmission has failed. Probably between $3000-$4000 depending where you live and the cost of labor at local shops.

High rpm shift


I'd have to agree with Smithbrother and go for the valve body control.........sometimes soenthing simple goes unchecked...make sure your tach is okay.

Sounds like it could be the throttle position sensor.

Engine dies in stop and go traffic while in normal low idle;coming off a high speed highway and the coasting ,engine dies also; starts up right away and then engine check light comes on and car works...


1999 300M 150,000 Miles

Car dies when coming off acceleration or at idle in traffic or at a stop. I can watch the Tach go to 0 RPM, some times it will restart immediately other times it is hard to start, so far I have always been able to re-start it and Drive on. Does anybody have verified fix for this issue, I have seen posts saying can and crank sensor, throttle body, EGR, and many more ideas... Do not really want to just start replacing parts with the hope that I eventually get a fix. Help...
