ok cheers lads, had the inejctors out, again thats not my problem

Ive adjusted the base idle as per my chat with stu

also I checked the rear earth on the block, not 100% sure but I think it may have been a dodgy wire on there, its to tricky to get at but I fiddled about with them a bit and the miss fire seems to be gone, to check I took the car out and just leathered it in first and second and no miss

ive still got idle issues but again as per stu's advice, I think its my throttle cable OR the throttle butterfly is a bit sticky, il strip that out tmrw and clean out the inlet and make sure its moving ok, and il try and adjust the cable

I checked the TPS and its the correct part number so must be the right one

will update tmrw thank you stu, TOP bloke
and cheers rock top dude
