Default Re: 289 idle - final solution







Just a follow-up to say thanks for the input and tell you the final outcome. I went to another mechanic who told me the valves needed to be adjusted. I had adjusted them three times in the last month all to slightly different criteria without improving the problem so I kept looking. Finally I went to a local mechanic with electronic diagnostic equipment and asked him to analyze the problem. Mechanics had unsuccessfully tried to solve the problem using diagnostic computers three times over the last couple of years. This person concluded that the spark duration was too short, replaced the coil and the problem was soled. This solution surprised me since there were no problems under load or at high RPM, which is where I assumed a bad coil, would show up.
