Hi Tom, Chris, and all,
Hope you don't think this silly...this is the way we "solve" problems at work...just throw out ideas till something "clicks" with somebody. Most often nonsense comes from the group till one little thing strikes a chord with someone...
Do you think it possible,
1. The way our coil pack fires positive/negative or whatever, could it contribute to the problem. Constantly switching grounds? (I don't have a clue how it actually works). Is the voltage supplied to it uninterrupted/consistent?
Does the MSD DIS-4 fire differently?
2. The way the O2 sensors switch...is the fuel program written too precisely and in need of a bit "fuzzier" logic? Can you put in a bit of "resistance" to slow down the switching? Smaller gauge wire?
3. I think I remember a while back changing my air filter and immediately noticing the "stutter"...apparently it had either reduced with a dirty/restrictive filter OR I had gotten used to it, (although not likely). Has anyone tried to restrict the intake to see if it makes a difference one way or another?
4. What would a faulty cam or crank position sensor result in?
5. Spark plug gaps too large?
6. Winter grade oxygenated fuel?
??????????????????????????
Also, my car does run BETTER when COLD, however it certainly isn't totally gone while cold.
...Ed
