The current shop will look into this but they are closed now ..
When i drive normal, it never happens. When i WOT and hit around 130 mph, it still doesnt happen. After i WOT, and the vehicle speed comes down around 40 or 60mph , then i cruise it, the engine light comes on and goes away real quick. Then there will be a stumble when trying to accelerate.
car was tuned before with stock heads, and fully forge internals to make it 426 stroker and maggie supercharger 12 psi but it didnt happen at this time.
Put in new pistons, rings, bearings, spark plugs, and new Thitek cnc ported heads then re-tuned. Reason i did new pistons, rings was because the previous shop did a bad job on my compression ratio which is a different story but now compression ratio is at 9.5.
Like i mentioned, regular driving it never happens, even when i accelerate up to like 100MPH without WOT , it doesnt happen. It doesnt show up even when i WOT, but it comes up after when speed comes back down and i am just cruising then i can barely accelerate cause it will stumble.
Anyways this is what i have done so far ....
- replaced spark plug, and swapped coil pack from 8 to 2 , and it still happened.
Thoughts ?
