2002 Z06. Bought with 30k+ miles. PGMFI light coming on in the first week. Turns out to be plug wires. Ran fine for 2 weeks. Check light coming back on and now it barely runs. Will not get out of the subdivision. Due to running rough and smoke out of the exhaust. What is going on. Anyone seen these symptoms yet? I cannot believe the car is crapping out this early on in life. I will need to test compression and leak down but It feels like bad electrical/ignition. Anyone have experience with this? Smoke?
