1993 Hyundai Scoupe LS review from North America

Air flow sensor. Numerous spark plug wire sets (5).

When I first bought the car it was great. Lots of pep, it kept up well at the light races in town. But after I washed the motor the car hesitated and had poor idle. I took it in to be serviced and I had to pay for a new fuel filter and new spark plugs. Seemed OK for about two days and the car was acting up again. I took it to another dealership because the previous one couldn't find the problem. The second shop said that it was a flow sensor in the intake, and also cleaned the intake manifold. Not any better. I seem to have found the problem myself after some trial and error. It seems that every time I change the spark plug wires it runs good until they burn up or foul some how. I've gone through 5 sets of cables, the last one lasted the longest - 8 months. Because I wrapped them with header insulating wrap to keep the heat off them. I talked with a shop recently which told me that it could be a faulty coil. I'll try that replacement as well as a new set of cables. I hope that this works. I enjoy my car and it is great when it isn't missing spark delivery.
