HELP!!! Car Dying :( I got a few misfire over the weekend and got new plugs and after I installed it, it ran fine. The next day I started it up and went to work. 3 miles from home car started to smoke and the car would hesitate once I tap on the gas and I limped to the office. Now I cant even get it to idle smoothly after starting it up? Anyway to diagnose this? I have EFI Live and I pull the readings but it's not showing me much?? because I don't really know what i'm looking for. The only thing I can see is that it's not misfiring anymore but the motor barely idles.
Could I damaged something while limping it to work? approx 1 mile of driving. also could the misfire cause the spark plug to go bad? I'm trying to see if the obvious will solve the problem. Any help is greatly appricated.

instead of draining the oil, drop the pan, should be able to tell whats going on them....your gonna see either copper or alumn...
also what are your spark readings, fuel trims, etc....how was the car tuned for the H/C swap? is the car heating up? what is the oil psi?....check back

I found the cultprit. Its a rocker that's loose... initially I can't figure out everything revolved around #1 cylinder then I took off the coil, swap the #1 with #3 and unbolted the valve cover and the rocker on the #1 cylinder was about to fall off!!! This is crazy... I am pretty disappointed in the people who did my heads/cam swap... that didn't do a good job on torquing everything down. But never the less my car is finally driving... Thanks everyone for their input.

Thanks!
