Title: 1.8 se spluttering running rough once warm
Post by: Gal on 24 February 2011, 21:26

Hi

I thought I had fixed this once I had put on a new coil plus cleaned out the throttle housing with carb cleaner. I have changed the plugs, dizzy and rotor arm. Awaiting relay 167 in the post. Also changed temp sender

Now I know the car gets up to temp, but blows out mildly warm air out the heaters. I'm guessing thermostat not working, but would this make it run/sound like on 3 cylinders once driven for a couple of miles?
It may be me but I'm sure its worse when damp and raining

I checked coil again for sparks by spraying it but seems ok

Why oh why did I get another mk3 when I prefer mk2's?

Well the plugs were shagged. Replaced them. This morning was damp and it juddered a little driving while cold. More so once warm and accelerating. Still waiting on fuel relay. Anything else I should check?

Thanks

yeah - change the thermostat.  Engine coolant temp is a key input to the ECU (coolant temp sensor) for fuel management.

just unbolt it - you don't need to disconnect it.

Thanks that helped a bit. Managed to get under there but wind and darkness got in the way. I still cant suss out which are which bolts are to undo it though.

Car beginning to pee me off. Once this done I am selling it!

I do mean that too. Going back to retro VW so if anyone wants a 1.8SE then buzz me
