hello I'm new here, and i was hoping for some help. Our S3 1986 XJ6 has developed some strange symptoms. At a cold idle, it often shudders and cuts out. We think one of the cylinders was misfiring before, but the problem has become considerably worse. From startup until the engine is warm, it will seem to miss and cut out entirely. This can be averted if you give it plenty of gas and the problem goes away once the engine is warm. We tried replacing one of the temperature sensors in the engine, and we found one of the hoses to the vacuum sensor (for the fuel injection) was loose, but the problem persists. If any of you could shed some light on the situation, it would be much appreciated
thanks,
the Andrews family
