Engine Performance problem
1996 Chevy Tahoe V8 Two Wheel Drive Automatic
I recently asked a ? regarding my Tahoe and an obd 2 reading of 0302 (misfire on #2 cylinder. Now I have another. Could my intermittant misfire be caused by a sticking exhaust valve? It doesn't happen until my truck starts to warm up usually about 180 deg. I've switched plugs and wires but the cyl doesnt change. also when I pulled the plug it appeared to have exessive carbon which leads me to believe the "injector problems" are not really the cause. Please help me figure this out as I have to visit family in less than 2 weeks and my funds are very scarce. Also if indeed it may be caused by the valves possibly sticking, is there a product that will remedy this or is head work my only option?
