Hi all, i'm tryin to fix my fathers 02 accent and things aren't adding up. Just looking for suggestions or the frequency of this problem. Anyway the car is running literally on 3 cylinders. Noticed the spark plugs were leaking replaced plugs and wires, to no avail still missing. checked for spark, fine. Unplugged each fuel injector in sucession, no change in #2 cylinder, swapped fuel injectors, no change, signal present at connector. I just told you that so no one would suggest fuel or spark. Compression tested each cylinder, approx 170-180 on cyl #1, 60 on cyl #2, approx 100 on the remaining 2. Which suggests to me that cylinder #1 is okay, because that is a normal value. It did not increase with each crank of the engine so i do not suspect piston rings. Also due to 3 cylinders acting bad I wouldn't suspect valves, first off itd be noisy and second off a valve burning or cracking in 3 cylinders is unlikely. I also removed the valve cover, the valve springs are fine and everything up top works as it should, I did notice minute traces of coolant in the oil, and some crud buildup, but very little. Which leans me toward head gasket, but what are the odds of a head gasket blowing between 3 sucessive cylinders.
I'm running outta ideas until i get the head off, but i'd appreciate any suggestions, which would save me taking the head off, cuz finding a haynes guide for that car for the tourqe specs is becoming a bitch. Plus is this common, cuz hyundai keeps telling me that its spark or vaccuum and I feel like punching them in the chops right now. Thanx muchly for any help
