Sounds like "bah, bah, bah, bah..."
My coil pack is good, I have replaced plugs, plug wires, timing belt, camshaft position sensor. After all this it did not fix it.
(The cam pos sensor was replaced because eng light code. Timing belt was worn [belt sprocket ribs separating]).


I don't notice stuttering while driving.

I always use economy 87 gas. Do not have bad fuel filter symptoms.

Could it carbon deposits...or something else?

 

If your doing this with the vehicle parked, you may be bumping the rev limiter, which prevents us from over revving the engine unloaded & having it come unraveled & making a mess!!!???

 

Thank you!
That's was it is. You are confirming what someone else told me. I'd been to two mechanics that didn't tell me that. All this time I thought something was wrong. Now I have a great running car. Thanks again.
