Here we go 2.0gti 1992, started to run crappy misfire when damp. I have searched back through years worth of posts and solutions. I have changed plugs cap leads and filters fuel oil air,cleaned throttle body cleaned out all pipes checked for holes,leaks. Fixed leak in exhaust just incase,had a new coil 6 months ago.I am waiting on relays from someone but they do seem to be working fine, also cleaned air flow meter.
The misfire tends to be worse when turning round reverse to 1st and is doing my head in i have noticed a ticking coming from the throttle body now though i thought it was tappets but if you hold the feed to the cold start valve it feels like that making the ticking noise.I suppose i can swap relays and see,also done a compression test that was spot on. Any ideas
