Help Car Stumbles and then goes into Limp Mode

556 Views 5 Replies 2 Participants Last post by  Look Stock
The search is down so please someone help. I have an APR chip , ATP downpipe and cat. I thought that the stock DV was the problem so i replaced it with a HKS BOV from ECS. The stumbling was still present. So ECS unpluged the MAF to see if that was the problem..... Nope that didn't work. So i am stuck with a sweet sounding car that runs like poop. To create the stumbling problem the car can be in any gear and all i have to do is apply more than 2/3 throttle input. I tried to see if the car would pull through the stumbling and it caused the check engine light to flash. What else could be the problem ?? ECU, Wastegate, N75 valve, fowled plug, or coil pack ?????

Random/ intermittent misfire, and Random /Intermittent misfire # two cylinder
I think this narrows it down to the coil pack, spark plug or the wiring to the coil pack

Okay if you have a vag-com open group 014 that should give you total misfires then 015 should be cylinders 1-3 and 016 is cylinder 4. Now move the coilpack from 2->3 and see if the misfires follow the coil pack. If it doesn't the ignition module might be bad. If it does it's the coil. We've had a couple go bad here in Houston and one was bad Coilpack and the other was a bad Ignition module.
