I was on a drive two days ago and after 10 min on the freeway the engine note changes and it takes more pedal to maintain speed. I found an exit and visually checked that my timing hadn't slipped ( it hadn't). My number 1 plug was oily and black, all others were fine. I have since changed plugs and the engine will not accelerate as cleanly as it had before. I have yet to check the plugs again since a test ride. Before this problem it had been running great for a long time.
The engine is a 2.0L, 9350 cam, 40IDF, 009 dizzy. |

Any ideas of where I should look, I rechecked the plugs and they are normal.
Thanks |

QUOTE(geniusanthony @ Jun 14 2009, 06:35 PM)  "My number 1 plug was oily and black, all others were fine" "I rechecked the plugs and they are normal" I'm not sure I understand your two comments... However, you seemingly have an issue with cylinder #1. As a short cut, start your engine then remove the #1 spark plug wire (careful you don't electrocute yourself). If you don't get any change in engine noise, you have confirmed the #1 cylinder as the root of the problem. It is electrical, fuel or mechanical based. I would first check to ensure you are getting a spark to the #1 plug (easiest check). Since you've got carbs, and you're getting fuel to the other three cylinders, I would not suspect fuel delivery, however, you could have an issue with the cylinder #1 intake valve, so I would check all of your valve clearances. The third thing I'd try is a compression test for all four cylinders. Good luck! Eric Read |
