Subject: 90 C4 performance degrades the longer it runs by jwardg on 2011/2/9 19:49:29
Its a 1990 convertible. I bought the car about 18 months ago and have done a series of tune up related repairs on it. Brake system overhaul, cat-back exhaust, plugs, wires, serpentine belt, etc. Overall, Id say, for its age, it runs pretty good....for the first 15 to 20 minutes. Then it steadily, progressively runs worst. As if to lose power, poor acceleration, skipping, missing, struggling. On my last drive, it ran for a while, then when climbing a small hill, it shut off. Not sure which way to go with this one. Anyone seen this symptom? Thanks . jwardg
