Hey recently purchased my mk2 16v gti and ran like a dream until weds when in the rain started cutting out and wouldnt idle smoothly (800-1000 surging) and when driving struggled and spluttered at 4k rpm, No amount of wd40 helped and dizzy was bone dry, then the day after cut out and wouldn start (in tge dry) at all not even try to fire...
I have spark and fuel...
I have since removed the throttle body and all air system and throughly cleaned out the air/ fuel metering unit checked all electrical connections (not earths yet) and now tries to fire up but just wont 'catch' and run.
If i press accelerator the engine tries harder...
When cranking engine a relay clicks every 1/2 second (cant figure which one or if it did this before)
Thinking possible relay problem? Which is for the ecu?
Any help or pointers would b helpful, thankyou!
