Firing on 3?

only things you could check is isv and look for any leaks on the inlet manifold etc.. to the airbox and all them little pipes, but they would make it run lumpy not what your describing. if you havent had the ignition timing adjusted etc.. get it shorted before you try anything else, you said its been sitting around alot so in all honesty it could be a valve thats seized or had it so id be 100% on everything else first.

checked for leaks on vacuum (found 1 small but didnt sort it)

it has now passed mot and actually passed the emmission! running rough, i have now also changed lift pump and fuel filter but still same, drove it up road and its gutless and tick over is worse and now lumpy, then tried unplugging the valve (the idle stabilistation thing apparently) and it ticked over better but still wont rev responsive (it takes a while then revs to about 3000 and sounds fine with revs held). Could this be the problem or does it just deal with the tickover???

thanks in anticipation (cant wait to drive the bloody thing! cos other than this its a very nice GTI)

Take the inlet boot off and clean out the throttle body, and while you're there check round the back of the inlet there is an extra blanked off vacuum hose here that is easy to miss!  I found it the other day and it was well knackered, replaced it and I finally have decent MPG!!

Your other issues sound to me like the static timing is out, mine was gutless and hesitated till I replaced the belt, tensioner & reset the timing.  Now it breathes fire!

will try all, its more off a misfire when accelerating (might be leads also?), its a game trying to find out whats at fault - the cheapest route! (what you have to buy first!!!)

might wanna change the rotor, dizzie cap, plugs and ht leads if you havent done so already there not expensive thankfully, but will rule all that out.  Think you pretty much covered everything else it must be something silly cause pretty much everything else has been mentioned and i think i mentioned the leads etc already just cant be A***'d to look.

check the socket on the side of the air flow meter. Try unplugging the lead wait a few seconds and refit. My 91 used to do the same but would stall when ticking over (drove me crazy) found out it was the connection to the meter. Also make sure all the air hoses leading from the air box are tight and not leaking air.

SUCESS!!

Typical, I fitted new lead, dizzycap, rotor arm and hey presto! so gutted that i didnt try the obvious first  :embarassed:

thanks all for your help

Excellent forum!
