Vehicle just had major tuneup including all ignition coils. We also replaced the fuel injector on cylinder 2 and it did not help. Maybe electrical to the fuel injector? The compression is excellent, around 130. I think it uses a little more coolant than normal (i run the ac a lot), but a leaking head gasket is likely not the problem with that kind of compression. I do not see any leaks. I used sea foam in the gas last night, a full bottle for 16 gallons. I t stopped the rough idle, and motor did not break up on a 30 minute freeway drive. I jumped on it on the freeway coming home from about 65 mph to 80 mph and the service engine soon light flashed for a few minutes and went away. Then on a side road I really jumped on it and the "service engine soon light" stayed on. It did misfire when jumping on it, but still a lot of power.
have the same problem?
