Multiple Misfiring...Help!!!
Multiple Misfiring...Help!!! Hey guys, I have recently bought my first LS1 so i don't know much about them. It's a 98 Engine with about 95k miles on it and all of a sudden two of my cylinders are misfiring. I already tried the wires and spark plugs without a change. BTW, the spark plugs had a bit of oil on them when I took them out (reason?). Where can I go from here?
The engine has Patriot LS6 style heads, TSP Cam, LS6 oil pump, Electric water pump and a Katech Timing Chain and Belt Tensioner...Also two electric cut-outs on the y-pipe which remain open since the little motors stopped working (someone mentioned these might be a problem since some air can be going back into the engine). Finally, the car has the LS1 Edit to run rich in Calif. but since I brought it to AZ I have't re-tuned it. Could this be a problem since I have to keep it at 1500 rpm whenever I start it so it won't die on me. Any help would be appreciated! Thanks
