I need some help guys. Like said above, two weeks ago my car started to hiccup under heavy load. If I'm at 70mph and I gun it the engine will hiccup. Even if I'm at 1500rpm and driving up a hill it will hiccup until the road flattens or I give it more gas but if I give it to much gas it will hickup.
I think it could be the following:
Bad plugs.
bad wires.
bad coils.
I didn't think it would help but I have run through two tanks of Jet cleaner these past two weeks just incase. I repleaced the plugs, wires and fuel filter about 12k miles ago but they still might be the problem. I just hate to pull all the plugs for no reason. Those that have done it before know why. My SES light came on just two hours ago and I don't want to drive it until I get it fixed. I called every parts shop in town but they won't pull my code (SOB's). A guy that works for my Dad has a good friend who owns a Pontiac dealer. He has told me he could get me the new GTO at cost if I wanted it....I told him I would be calling him soon and to hold that thought :D . I'm going to give him a call on Monday to see if his buddy would scan it for me. I wanted to hear from you F-body guys first. Thanks a bunch.
