ok was on track yesterday at combe... had an annoying misfire all day ..
eventually changed plugs and coil ( a group and c57's set at 25 tho) this cleared it ... also rotor arm , cap and a different set of leads..only thing not changed was the ignition amp..

when it does do it the rev counter goes off the scale. someone noted thet the actuator looked like it had been wound out (clean threads showing) so it could of been longer but that should give me less boost

but took martoon out on the last session and it reappeared with me only being able to get a top speed of 100 down the straight(was hittin 125 when it ran right)

it only did it on boost and didnt do it on every session . it was ok on the drive home and was faultless on boost... .


spec is a1 stage 3 chip,greens and 3 bar running 20 psi on standard turbo and possibly standard copmression/engine (103000 miles) but it dont smoke or anything like so i think its had a rebuild at some stage was set up by madevelopments about a year ago and has been fine untill combe

anyone got any ideas ... im getting quite miffed at the thing now
