I've got an issue with my Revo stage 1 1.8T.
Well when I got my car back I noticed that there was a "jerk" as you let of the accelerator but stayed on the throttle slightly, nothing wrong if you let off completely. It was definitely an engine running related problem, not a mount or anything.
This was annoying but not the end of the world whilst I tried to diagnose it. Unfortunately, it just got worse. I pulled away from a roundabout and it hesitated massively until I let off, then did it again. Then it would clear for a bit, then do it again. When it did pull fairly normally it still wasn't right. I pulled into a petrol station and unplugged the MAF to see what the difference was. It made it a lot worse. It got better as I got near home, but still not normal. The only other weird thing is it dropped to 20 miles left just before home, but no warning or beep to tell me?
Anything obvious I can check/replace tomorrow? I've got to be in Poole and really don't want to like this.
The only thing I changed recently is putting the S2k filter on yesterday but I can't see that affecting it and it was fine on the test drive.
I should point out it is running on high octane, and has a Forge splitter fitted. I know these are a no no, but it was on the car for around 2 years the last time I owned it with no ill effects. It's set to recirculate.
Any help would be appreciated.
