Car details:
P reg Golf GTi 2.0
Think engine is AGG
Mk3 8v
Did a good long journey with no problems yesterday, then did a short journey in the evening and hit a few problems.
The car started stuttering when I was going slow (round corners for example) then died completely when I got where I was going.
Wouldn't start at all, so got recovered to home.
Found that a piece of pipe I had used to block off two small inlets on the pipe that runs from the throttle body to the brake servo had popped off (it was a replacement pipe after the old one split. The original had 2 small caps blocking the inlets). I know it doesn't run with it off, so replaced it. No luck there.
Today I checked for a spark from the coil and plugs, all good. There was petrol getting to the engine. I managed to flood it, so let it vent for a few hours and dried out the plugs.
Just stuck it back together and still no joy. Engine will turn over, but not fire up.
I'm running out of ideas now. Searched on here and not found anything I havn't tried already. Has anyone else got any ideas before I give up and push it over the road the the garage? (luckily it was booked in on Thursday anyway for a CV joint

)
Trying to find my Vag-Com cable to see if anything else shows up there. But recently moved, and think it is still boxed up

EDIT: Throttle body is clean, and I had a look in the distributor as well. Was a little corroded in the contact points, but cleaned it up a bit.
Could I have gotten some contaminated fuel? Had filled up just a bit before the long journey yesterday.
