My 1992 Subaru Legacy Wagon is missing, I have changged the plugs and wires. It runs fine on the highway but has a problem in town where there are plenty of starts and stops. What else could be the problem?
You could try checking the EGR valve to see if it is dirty. It may be running badly at high speed also as it's harder to hear misses at high rpms. You should be able to tell by your acceleration and gas mileage also. Timing chain problems sometimes show up like this. Sorry I can't give you anything definitive but hopefully this will help a little. Good luck!
