Golf mk3 1.4 won t idle or rev up

[flusted 0]

Ive just got my girlfriend a 1.4 mk3 as her 2l gti is too costly to run. Unfortunatley the mk3 wont run and its on my head to fix it.

Ive checked theres power at the lambda, its had new fuel filter and BTS but it will not idle and when you rev it just bogs like its out of fuel?

it starts everytime, just wont rev up freely

heres a vid to try and explain what i mean

 

 

Im wondering if its carb, dizzy, blocked cat??????

 

got to fix it as my reputation is on the line :lol:

 

Can anyone help????

just changed the carb for a known good 1 and still the same. also checked cambelt alignment and its spot on.

Also changd fuel pump relay, no difference.

Is there an ecu relay? what number/position?

Can't play vid for some reason, and know nothing about that motor, but from your description you may have an air leak on the inlet side somewhere or choke/cold start is sticking on. In both cases ballsing up the air/fuel ratio.

yeah, you have a throttle body not a carb, but they do look similar so it's fair enough.

 

My mk2 jetta used to do this, check all the little tiny vacuum pipes. You'd be surprised how much of a hissy fit an old engine will throw if the tiniest pipe isn't connected!

 

Also worth checking your blue temp switch if you have one?

 

Also, has it been running recently? If i left my Jetwagon for a while it would also throw a hissy fit and do what yours does and need a good drive.

 

try some aerosol carb cleaner through it too.

fyi according to haynes mk3 manual relay pos15 == engine control unit relay

excellent will try relay today.

its had a new BTS although if you unplug it the problem isnt as bad?
