96-97yr problem please help

[steevo_02]

here is the problem with the G20.

-bad vibration at idle; whole car shakes-stalls A LOT at idle-rpm fluctuates while driving seems as if it is about to stall.

-after about 60mph car is much better

I'm assuming the problem is ignition related, right?well if just start out changing my plugs and wires, would that help at all?

please let me know what you think.thanks for your time.

Did this come on over time or did it just suddenly start acting that way? Does it bog and heave at idle as well, or just at low speeds? Those symptoms seem to me like a bad vacuum leak or MAF sensor, depending on the answers to those questions.

Ignition makes some sense too. When was the last time the plugs were changed?

sounds like vacuum for sure, just pop the hood and hit the throttle a couple times or have someone else if u cant reach it, and watch and listen around the whole intake for signs... u could get the plugs and wires but if u wanna save money i would check for leaks first.... if u think u found a leak try to fiddle with it and see if the car stalls

[steevo_02]

it wasn't always like this... and it has been getting worse as time goes on.

Check MAF ground, check TPS voltages. Check plugs, check Distributor cap & button. Vacuum leak also cause these symptoms.

If it's getting worse, then it's probably an expanding hole in a hose or something. If a sensor went/is on the way out, it'd probably have been sudden.

[steevo_02]

the stalling only occurs when the car has been driven for a while... apon cold start, it doesn't stall.

Is your water temp. gauge reading strangley? Sounds like the coolant temp sensor issue I had.

[steevo_02]

i changed the plugs, fuel filter, put seafoam injector cleaner in it, adjusted the TPS... hmm I think its a little better now.

oyeah, and edit the year that I first posted: its a 95 model year
