Car doesn't seem to be running quite right lately so plugged in vcds to have a look
No fault codes
But on logging i have misfire on cylinder 3 and 4
Replaced coil packs, plugs and done a compression test and all held about 160psi!
Then when I was looking at other bits i found out its running too lean
I replaced the cam follower and its still the same.
Heard that vacuum leaks can cause it to run lean so replaced my forge dv for the better oem one and my pcv blank to the oem pcv. Car still runs crap!
Rail pressure is fine as well.
What else could it be?
Anyway i can check injectors using vcds?
Any help would be much appreciated
Cheers Dom.
