HELP!!! Anyone???
Hi All,
I have a 93 325is with a ERT/Dinan Powerdyne Supercharger, I recently noticed when I rev the rpm over 5K on partial or wide open throttle the engine would seem to misfire/hesitate accelerating.
My boost gauge would still give full boost pushing 5-6 psi, but I takes longer to get going after 5k until it hits redline at 6900 rpm.
I changed out the coil packs, still the same...next I changed the plugs from Denso Iridium IK20 to Autolight Copper (1 step colder). After the change the car seemed to run better, but still the same misfire/hesitation.
Any suggestions? anyone experience this problem?
Thanks
