Finally got my car started. But it breaks up and sputters hard at 4500 rpm and hesitates badly on accelleration. Is there any test I can do to isolate the problem. So I can fix what's wrong. It is still a blast to drive with the problem. (IMG:style_emoticons/default/driving.gif)

Since you have electronic ignition, the dwell angle is not a factor unless the module is breaking down.
1. Age of spark plugs wires - if they are old they can cross fire with each other and/or to ground. 2. Check for high tension tracking inside the cap (black tracks running down the side or between poles. 3. I assume you do not have a rev limiting rotor - if you do, change it. 4. Spark plugs - new or ?. What type. 5. Bad tracks in Throttle Position Sensor 6. Dirty or defective trigger points. 7. Mal adjusted valves or weak valve springs. Just a few guesses................... |
