I just got a service:

Oil Change
Oil Filter Change
Spark Plug Change
Belt Change

We were hoping to have a retune for the car but something weird happened. I can't accelerate at all. I sometimes have a hard time problem starting the car when it is cold. After I start it, I am trying to accelerate. Accelerate meaning daily driving. The car is breaking up like crazy. 3000rpm 4000rpm the car breaks up and it won't accelerate i can't pass 3000 4000 rpm. feels like it is cutting the ignition. i get huge backfires sometimes. Friend of mine recorded a video. Not sure if you can understand what's going on but if you turn up your speakers you can hear it.

off subject cause i dont know the answer but was that lightning in the background or a cop pulling u over at the very end..

 

it was a lightning...

 

check the gap on your sparkplug..that's what happened to my big turboed Audi A4... 0.028mm and 0.032mm made huge difference...

 

its's amazing how gap being off just a little can make a big difference.

 

I tried both 0.024 and 0.030

 

i had something similiar but with a vacume plug on the valve cover and not a spark plug. it wouldnt let me go above 3000 rpm. hope you get it all checked out.

 

what spark plugs did you use, cuz i believe oem sparks don't need to be gapped...
