I put in a new spark plug and the wiring harness has been replaced so I'm pretty sure it's the injector that's the problem. I'll try the stethoscope to see if I can hear anything unusual. I suppose the injector leakage test and spray pattern test requires special equipment at a shop. I guess I can also try swapping injectors to see if the misfire follows the injector to the other cylinder.

When you determine the injector is the problem, you can send it to http://www.cruzinperformance.com/fuelinj.html. For $12 + shipping he'll clean and flow test it for you. The flow test will tell if it's ok to use.

Rich is the owner/operator and you can call him to verify scheduling. I'm a very satisfied customer.

Bob, thanks I think I will try that - given the cost of replacement injectors these days.
