Car starts then stalls, have to keep foot on gas
I have a 97 Pontiac Grand Prix gtp. My car starts
then stalls, I have to keep my foot on the gas to
drive around and if not it dies. Codes came up for
mass air flow sensor, and throttle body position
sensor, replaced them and car still does the same,
then I checked the map sensor and noticed the
plug was destroyed, I fixed the plug and replaced it
with a new one, codes came up for a pcv valve, so I
replaced that with a new one and car is STILL doing
the same thing, also my mechanic said my super
charger is on its way out, now that's the 1st one I
had to buy for him to put in, he said he put marval
mystery oil in it and now says the ball bearings r kn
it's way out, can I just buy the ball bearing kit off
eBay and replace them?
