99 Firebird 3.8 trouble...help...
Hi,
I bought a 99 Firebird with the 3.8 V6 2 weeks ago. The car is near perfect with only 47,000 miles. A girl owned it and drove it 4,000 miles in the last 4 year, only putting on 800 last year after having new plugs,wires,filters changed, then it sat from Sept. 07 until I bought it. When I picked it up they had just started it for the first time since last sept. and it was almost out of fuel, was chugging, dying at stop signs, etc. I figured it was just bad gas from sitting, so I payed for it and drove right to a gas station and filled her up with premium. Well, it runs great on the highway, has lots of power, but after 500 miles of driving and adding seafoam, injection cleaner, etc, it hasn't gotten much better. I them assumed an injector was stuck open, went to the local junkyard and bought a full set of injectors. It idled great right away, but as it warmed up it went right back to the same thing. It is obvious that it is getting way to much fuel at idle, it gets loaded up after a few minutes of idling, where you have to revit good to get it cleared out. It runs perfect down the highway, is faster than I ever thought a 6 cylinder could be without a hint of a miss. It is just getting way too much fuel at idling and low speeds. Any ideas ? The local advance auto says the codes say rich condition on right and left bank and misfire. I haven't had it to a shop with a real scanner yet, just wondering if anyone has had a similar problem before I spend more money. Thanks
