#1: GTi 180, running on 2/3 cylinders Author: sri16v, Location: WalesPosted: Sat Jun 25, 2011 7:57 am ---- After putting the clutch in my 180, connected everything back up as per usual and went to start it. Immedietely it was running very poor,
I have checked the injectors as I suspected it was a bad injector, they are all firing nice with a good spray pattern,.
Ive changed the plugs back to another set, and still no joy. Checked the coil pack and it appears to be working, but you cant really tell a weak spark that easy.
The plugs themselves are black and sooty, not wet, but not the cocoa brown youd expect.
Its not logging any fault codes, and Im scratching my head, hoping its just a coil pack, but would that log a fault code?

crank sensor did have a little bit of damage, a rough edge from what I remember, im guessing it was from when the release bearing exploded, as I dont think we caught it when putting the box back on.
Would the damage not bring up a fault code? or do you think it may only be partially working?

#7: Re: GTi 180, running on 2/3 cylinders Author: sri16v, Location: WalesPosted: Sat Jun 25, 2011 3:32 pm ---- bit of an update, after running a compression test, cylinder 1 nearest the cambelt had a reading of zero, no.2 was 160, no.3 135 and no 4 160.
Stripped off the inlet manifold to investigate and found a piece of plastic melted onto the inlet valve holding it open, have managed to remove what appears to be a cable tie from the valve, found another bit in the inlet manifold itself
Im going to run it tommorow and hope it gets hot enough to burn off the rest of the cable tie, as I dont fancy stripping the head from the block for a piece of plastic.
any tips on bleeding the clutch?, just seems to be constant air coming through the bleed nipple, and still no pedal
#8: Re: GTi 180, running on 2/3 cylinders Author: sri16v, Location: WalesPosted: Mon Jun 27, 2011 11:23 am ---- all sorted, running sweet as a nut, car started on 3 cylinders but quickly settled down and ran on all 4. Had a bit of valve noise for a while but a top up of oil and all is well.
Bleeding the clutch was a nightmare, couldnt get a pedal, so used a bleeder that attaches to a spare wheel @ 20psi, bled it instantly.
Had a few fault codes stored from carrying out the compression test, but soon cleared them. Next job rear discs and pads.
