When cold, If I rev the car (driving or neutral) to about 3-3.5k usually it shutters and will not increase, not even like a miss on 1 cylinder, its multiple because she basically dies. If I granny shift, sometimes when I am at op temp, the car can pull to 4.5k-5k pretty decently, but then will have a slight miss above that.
Coils are all ohm'ing at about 1.2 ohms. All ignition components are n/a on age, but visual inspection yields no concerns. I am just confused on why the shutter would happen later in the rpm band and not as bad when its warmed up?
Someone recommended checking the afm, since I did have a code for one (might be an old code, not sure how to delete codes). The carbon track did not look too bad, but with the age 2 of the 3 bolts broke off holding the carbon track. So eithor way, I would have to start drilling and whatnot to really relocate the track ever so slightly.
I am wondering if its an issue with an open loop sensor, since the pcm would use these parameters during warm up. Any Ideas?
