Question about 1997 Pontiac Grand Am

1 Answer

My 1997 pontiac grand am is revving very high at idle, and when I drive it will accelerate on its own. It shifts ok. When I try to accelerate with the accelerater the car bogs down. What the heck is going on? I feel that it could be a sensor, but I would like to narrow it down a little.

1996 Pontiac grand am she will not accelerate when shifted into drive or reverse. It idles great in park but drowns out in drive and will not go.

Although I'd need more information for a better diagnosis, I suspect that your idle bypass (Idle Air Controller) has failed or has become disconnected. When you begin to feel the car faltering after moving the shift lever into DRIVE, try giving it A LITTLE extra throttle (just enough to keep it running) with your foot FIRMLY on the brake (so you do not propel yourself into something). When you release the brake, if you can drive the car normally until you release the accelerator, your problem is the idle bypass circuit (probably the IAC itself).
If the car still stalls out, I'd need more details to give a diagnosis.

1998 grand am gt 3.1 litre... When I am driving the RPMs are high (3000) but I have to really push on the gas pedal to get the speed up to 25mph

It's called Bad Transmission, it's slipping...either low on fluid or Burnt, time to replace it or rebuild it

What is the switch for in the lower left side of the dash on my 1995 Pontiac Grand Prix, it's labeled, start in second gear

with switch on, the transmission will not shift into 1st gear--it will start in second and then shift to third, etc.. This is OK for normal driving, but not if you start on hills or want to accelerate quickly from a stop.
