I'm having issue with cylinder 2. starts fine, not really rough idle. complete loss of power and chugging/sputtering after 2100 RPMs. new spark plugs, new fuel injectors, complete new catalytic converters, new O2 sensors. I just did a compression test on the engine. numbers seem fine. i noticed that cylinder 2 spark plug was covered with carbon. All other spark plugs were fine. The p0202 code keeps coming back along with 2 O2 sensor codes. I can also hear a vacuum leak when the engine gets up to normal operating temperature. It's coming from around the intake manifold. Will be fixing that once I track it down. Still got to figure out that cylinder 2 issue. Would there be a problem with the exhaust valve in cylinder 2 not operating correctly?
