Hey guys . I thought I had a misfire but after replacing coil packs and overhaling the injectors I have the same symptom. When I accelerate from zero to 50mph I will get 2 or 3 major stutters. I now think it may be tranny related. I did change the vss recently. I could just be low on tranny fluid. Any body ever had this issue. I can't believe I'm the only one lol. Thanks

 

What are the error codes on the computer?

 

no engine light , no codes

 

No engine light , no codes

 

Have you checked the transmission fluid level? It's supposed to be a closed system. If it's low you have a leak.

 

You may have a code that does not turn on the engine light. Does your OBD2 scanner check all the modules, including the transmission module? The less expensive OBD2 scanners only see codes related to emissions.

 

Fuel filter genuine?
