I have a 91 Camry LE with 180K miles. It recently failed the HC portion of the Texas emissions test. As this is often caused by misfiring, I connected my inductive timing light to each of the plug wires. I found that there was a patterned miss in each of the wires. This lead me to believe that there is a problem with the distributor. My question is "What should I do next to find the problem?". BTW, I changed plugs and wires last year when I passed the emissions test. I would appreciate any suggestions.
Thanks, Al Kondo
