Engine Performance problem
1999 Chevy Lumina 6 cyl
It all happened one day when I started the engine in the morning and noticed a very rough idle but soon went away when it warmed up. Then I got a fault code misfire cyl. #1. I tried new plugs, wires, no good. I had the injectors cleaned proffesionally, no good. I replaced cyl. #1 fuel injector and seemed to run great for the first day, 2nd day started all over again and getting worse. I did a compression check on all 6 cylinders and they all held @ 160 for at least 20 minutes each. I did notice that I am "very slowly" loosing coolant but do not know from where and sometimes you can smell the burning coolant when engine is hot.
Any suggestion's as what to look for next?
have the same problem?
