MK 4 Golf Engine revving
« on: September 13, 2012, 01:56:37 pm »
Hi,

My golf is revving to 1500rpm itself when i take the foot off the accelerator, every so often. Any ideas what is wrong? Its a 1999 mark 4 GTI.

Mark

Not the throttle cable. MAF?

Hi Mark, forgive me, but a Mk V Golf GTi from 1999, are you sure?? If the rev's are going up by themselves, i'd suggest a PCV valve problem... :confused:

to be honest mate, not even sure what it's actually for, but if you do a search on here, you'll find a whole host of information about it. As yours is a Mk IV, it might be another problem, somebody here might be able to give you more help on this than me though...!!??  :confused:

Mk 4s dont have the pcv same as the mk5, as said could be throttle body sticking, maf, diverter valve,  you could do with scanning for fault codes.

i had this on my old mk4 1999 1.6.. i changed the MAF and cleaned the throttle body out and it was fine.

go over to uk-mkivs forum this problem pops up a lot and theres a lot of great writes ups  about it if you search.
