Help - Misfire tonight

[simon67]

Just finished the chassis grinding, painting and waxoiling so I thought that I would treat her to a good run. I started to notice a misfire at about 80 & then it went away. Returning home it came bach and got progresively worse - major kangaroo type motion & very embarasing. If I knocked her out of gear it reved beautifuly. Back in gear and she was poping and banging. Anyone got any ideas? My hunch is fuel pump / filter but I guess that this is going to be one of those problems that takes ages to find & will result in everything being replaced before I fing the real fault

Cheers

Could be the throttle pot?

Get the car warmed up take it for a spin, if it still does it, unplug the throttle pot conector and give it a run again. If the faults gone its the pot. remember the car won't run quite as well with it unplugged as it will remain on a basic setting, but it will give you a good idea.

Cheers folks, will try throttle pot tomorow. As I've just sold my van it's S2 everyday now so do need to get it fixed quickly. My other line of attack is coil as the problem seems worse under load

I think that I have solved the misfire. Disconnected the throttle pot & it ran exactly the same (big misfire when giving it a good boot). reconnected throttle pot & everything seems great. i can only assume that the connection to the pot was a bit dodgy.

Fingers crossed for a big run tomorrow!

Well done mate. obviously give all the connector blocks a good clean all round on all the sensor plugs and it should keep it all ok.
good luck.
