Title: Mark 3 GTI firing problem, help please
Post by: tomellson on 19 July 2011, 16:08
Hi guys,

Ive got an 8v gti which has been playing up a bit.
I broke down on the motorway yesterday with a complete failure of the coils where the engine did not fire at all. the failure occured at 70mph at about 3k rpm and there were a couple of splutters before it failed.
I got the AA out and they diagnosed and changed the coil amplifier.

Initailly this fixed the problem and i made it home but the car still splutters and seems to be firing on 3 cylinders until about 3k rpm where the 4th kicks in... has anyone got any ideas what the problem is and how to fix it...?

Many thanks guys

Tom

MAF I reckon. Take it off, open it up very very carefully and even carefuller  :grin: clean the element with contact cleaner and a cotton bud. Worth a try and cost nothing to do too.  :wink:

How do the HT leads look one could have broken down if you think its firing on 3 cylinders maybe worth a little service like plugs, leads, filter, oil etc also clean the throttle body with carb cleaner always helps  :smiley: Check the wiring to crank position sensor. Sounds like leads possibly though spray a mist of wd40 on them when its dark and se if theres any sparks  :smiley:

thanks for your replies guys. appologies a few extra questions...

Whats the 'MAF'?

I will do all of the above and report back...

Incidently i have been looking at threads on here and some of my symptoms seem to point to the fuse for the relay for the coil going? i take it as my car still runs it wont be this??

I have exactly the same problem on mine, cleaned the maf and throttle body now going to look at the rest of it. Be careful with the maf it's too delicate!
