My problems was a left front speed sensor, and an oil pressure sensor.

These cars have lifter tick and piston slap. Its a common noise that shouldnt really be worried about. If they in fact did come loose. 167 ft lbs is what the rockers need to be torqued to i believe it was.

Inch LBS ... Not Foot LBS

The spark plugs I have are the denso Iridium spark plugs.....I thought I got the acdelco, but didn't. The website for denso says pre gapped at .044. I looked up some on there info and thats what it reccomends for the grand am.....So should I gap them, and risk damaging the electrode? Or just go with the .044?

With iridium tips, no I would not gap them. I'd leave them at what they are at. It's just not the recommended gap. GM recommends .06". I'm surprised yours are .044 because I've used Denso and NGK's before and they were gapped .055. They were different heat range from stock though.

A smaller gap makes it easier for the spark to jump, which is why boosted engines sometimes run a smaller gap to keep the higher cylinder pressures from "blowing out" the spark and making a misfire. A wider gap makes it easier for the spark to be exposed to the air/fuel mixture though which makes for easier light off and better combustion. They usually recommend running the largest gap spec'd unless you have a misfire. In your case with a basically stock engine though, it's not going to matter one way or the other. .06 would be better, but running .016 less gap is not going to hurt your engine.

Well just finished up! It runs excellent, and the service engine light went out! I pulled off the back valve cover, and cylinder 3's rocker arm studs were pulled loose. I drilled them out, tapped them, and put heli-coil inserts in. Then put them back in and torqued them. I then checked the torque on the others, and there were a couple that weren't torqued down all the way.

I pulled all the spark plugs......Man what a mess.....There were 3 different types of spark plugs! They were all gapped differently. The closest to being right was .065. The others were all scattered from.075 to .085! I could also see where the plug wires were arcing on the insulator of the plug....So new spark plugs, plug wires, and fixing the rocker studs solved the issue. Idles, and runs great now. Thanks to everyone for the help!

Good to hear.

Yeah, you should always run the same plugs all the way around, with the same gap. And make sure the plug wires are in good shape and pushed on all the way. You were probably getting a severe misfire.

Yea I know! I can't believe I haven't had a misfire til now! I usually change the plugs, and wires as soon as I get a car, but this one I didn't for some reason........
