Vacuum leak causes high rpm and hard brake pedal; it can also cause rough idle or you need a tune-up.

Does it have the 2.3l Quad 4 engine? If so replace the plastic piece that the coils go into, they go bad and leak spark to the cam towers and then you get a nice one or multiple cylinder misfire.

"...should not have to have to deal with these issues"

Agreed! But, there seems to be a glitch involving the ABS and TRAC system. On my 99 GAGT, when the eng and tranny are cold, I tend to get an ABS fail during turn/brake instances. If I restart the engine, it generally goes away. I've done a bit of research and have found nothing that fives a definitive answer to this. If you take it to the dealer, it will cost an arm and a leg for the troubleshooting alone. I'd recommend driving it as is provided you can get the ABS to reset by restarting the engine.
Sorry I can't provide any better solution...

SOURCE: 1999 pontiac grand prix . will not run

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

The service light means something is wrong with the car and it needs attention now. Get the codes checked and that will tell you what is wrong with it.

No.

My 2003 Pontiac Grand Am GT has a flashing and sometimes a Solid SES light and runs rough


Usually with the newer vehicles when it starts to run rough or idle poorly it's time for a tune up, that will also make the check engine light come on on some vehicles, it needing an oil change can also cause the light

3.1 engine 96 misfires trough driving speeds and idle


i had a 94 that ran into problems like that with very rough idles and misses. i get about five different codes from injectors to oxygen sensor. turned out my negative wire from the battery was so corroded inside the insulation it was causing all sorts of problems. bought new cable and ends from canadian tire $40.00 and installed (had to clean the connection to the block with sand paper) but fixed all my problems after that.

Running rough, no power misfiring


i had that problem once. when i got under half a tank of gas in the tank. What i did was i dumped one bottle of gas line deicer in the tank and i have never had it agian. you may have some water in the tank. from condasation or i have a stong feeling i got my water from the gas station. i was using the same station all the time. so i tryed another gas station and so far no more rough idleing which was caused by the water i think and i am getting better fuel milage to. i hope this helps.
