Right, so! I have finally had time to carry on with the beast
After trying in vain to get the car to idle, I thought I would check all the wiring in the engine bay! Thanks to Mike_25th on SWdubs.co.uk, he sent me a copy of the Autodata info for my car so I had values to check against! after checking everything else, I checked the loom section going round the back on the block to the Throttle Potentiometer Switch, Throttle Closed Switch and the unused heater plug. To put it simply, the three wires on the TPS plug are literally falling apart lol! How I missed that the first time I checked the loom I have NO idea!
Now if that doesn't sort the idle problem then I don't know what will!
I have been recommended an auto electrician called John Harrop, based in Exeter, so he is booked in to come and sort the wiring out 9:00am on Thursday morning!
I'm off to go and wash the car in the rain!
