Okay this happens intermittently so sometimes its fine.. sometimes its buggered.
Sometimes when coming up to a stop when i put the clutch down my revs jst die and the car stalls.
Sometimes when i start the car it revs a wee bit then stalls.
Then again sometimes its fine..
Sometimes whilst driving and once pressing the clutch the revs stick.. so say im doin like 2.5/3k revs and i either take my foot of the accelerator or put the clutch down, sometimes the revs will stick there and itll rev on its own.
One thing i noticed the other night when i started it and it was trying to stall, my headlights and dash light were dimming as it was going to stall.
Thought this was a tad strange.
Anyway any input is welcome as i have no idea whats up.
Cheers guys

most vacuum pipes pull off easy enough. With the engine running stick your head in the engine bay and listen out for any hissing type noises. Get someone to rev the engine a few times aswell.

idle control valve will probably need cleaning

Cheers guys.

imo vac pipe is unlikley because i cant see it bein off sometimes and back on others! sometimes the t.p.s (throttle position sensor) causes those symtoms needs a new 1 tho to fix it so would get some diagnostic work done on it
