mine is identical bud, when its cold it flies but when it gets warmer it feels like an XR3i

gonna check mine over for those parts - let me know how you get on

another thought, have the emmisions checked out, if its running very weak when warm this could be causing your problems, when its cold it will have a richer mixture

rs_turbo_lad

yes no problem, i will do, yeah mine feels like xr3i aswell its annoying me.was gonna try a front mount on mine to see if that would cure it but prob not,let u know

rs_turbo_lad

ok bud, gonna giv the dizzy and plugs etc ,leads rotar arm ,then if not cured i will prob see if emissions will get it sorted cheers

Question -

If it was spark plugs which is a main part for SPARK ignition how would this effect when warm? Unless there not working which means a miss fire and no spark = to not running. how can it change or diffa when warm. So to answer that it wouldnt start or run if there not working correctly.

My first option would be to get it checked out on a comp. This would show the problem for a sake of 50pounds.

So it boost's fine untill warm. I wouldnt say its a boost problem as such. HTleads wont be ur problem nor ur plugs. If it was ur dissy cap then it wouldnt boost whats so ever, boost leaks = no boost and emmisions is ur fueling which is no relevence to your boost but can effect the timming and running of the engine.

Anyone can say, man try thus but i would take it to an expert who knows whats wrong as no offence ment to anyone on here but my advice is to take it to be tested as it could be anything.

alright mate, i think i have solved mine, changed the throttle position sensor and now mine is boostin a lot harder - worth a try
