Decided to finally fix the miss fire I was getting under open throttle from 4.5k up in my ba typhoon. According to my mechanic it was the plugs and coils. However after putting a new set of delphi coil packs in and some plugs in it made the issue even worse. Has anyone else had a problem with delphi coil packs. I changed them over for vdo coils. Hopefully it will fix the issue when I put them in.

So far u have bought the two chittest brand coil packs bar weapon x

Repeat after me

GENUINE COILS ONLY !!!!!!

Best to use genuine ford coils

Cheers for the quick replys. Best place for genuine coils is the dealer im guessing? Has anyone had any luck with the vdo coil packs at all :s

vdo were in my car and fine till they stuffed up similar to yours and I sold whole car anyway.

ive heard of others running them.

I still hear genuine are best

Ok so I put the genuine ford ones in and the car is still miss firing very hard under load. Pretty sure the car is running very lean as a mate plugged in his diagnostic scanner ane the plugs showed signs of leaning out. Would that explain the issue.

Car standard?

Tuned 330rwkw 15 psi. 60lb dekkas, 7 psi actuator. Hiflow cat etc. Was recently re tuned and serviced. Has been misfiring for a while but been getting worse and worse.

It feels as if it's cutting out of fuel when it hits boost

Dude if u want u can bring it up the shed and we will spend some time with u and sort it out if u want ( I dont know who tuned your car and do not care but just offering free advice/help if your tuner wont )
