running issue

[danmusic24]

ok so im looking to sell my golf,just getting it ready for mot.the car has not moved in a long time so thought i would give it a blast down the road to blow out the cobwebs.had a running issue before which turned to be a split vacum hose which i sorted and seemed to run ok for while.
the car runs fine when plodding along but as soon as you floor it the car seems to pull back on accelaration.i have changed plugs and usaul suspect like coil crank sensor and lots of senors and relays,but still pulling back.
any bright ideas anyone?

dizzy cap and arm?

Clean the throttle body and the MAF too.

changed cap and arm a while ago! i cleaned trottle body and changed maf with a few spare ones i have,that was my first thought...the strange thing is vagcom aint showing up any faults..
starting to think ecu is breaking down but vagcom links to it ok so maybe not.its doing my headin

[javalin]

doubt it's ECU, and the ECU on the mk3's doesn't seem to show faults really.  I think later generations are better at that.

Spark plug leads?

All other hoses ok?

bloody hell! ive been over the car with a fine toothcomb mate! and the only thing i aint thought about is the ht leads,what a muppet! will garb a set a try it,i spose if they are breaking down that would explain lack of power when booting it.
cheers dude!!!

cool.  Suggest the GSF ones for the GTI - running them on my 8v (114bhp) - 118bhp on recent RR. :-)  Don't buy the cheap and nasty's.

Air filter?

do they do different types,i mean cheap ones or expensive ones or shall i just ask for gti leads?

[javalin]

yeah they do gti and non gti leads, but gti ones are nicest. (unless you have a VR6 of course!)

I think they are "I think its part “92631F” desc “IGNITION LEAD SET-BQ G3 1.6/1.8/2.0 GTI 8V”"

but get the 16v ones (as I think its a 16v you have?)

[javalin]
