Question about 1999 Pontiac Grand Am GT
My car has a problem staying running for more than an hour, I have changed the spark plugs and cleaned the coil pack and no matter what we do we can't get it to stop, it will start sputtering after about fourty five minutes and if I continue driving it will continuously stall and even when I give it a little more gas it get's worse nothing I do seem's to change the problem, I have put it on my buddies diagnostic tool and all it say's is that the vehicle is running lean and I would like to know of the possible way's to fix this problem.
Use a fuel pressure gauge and see if u can trace to to injectors also try running some chevron techron injector cleaner u might just have clogged injetors
