The ISC may be buggered, Try tightening up the 2 bolts.....Or the ISC gasket may be buggered.

will have a look tomorrow, i'll let you know how it goes.
also the car has stalled on me before at lights. and sometimes when i brake it feels like the ISC is fighting against the brakes. i guess its preventing stalling?

the isc appears to be fine... gave it a clean. the gasket is intact and the bolts were tight as sh*t.
still doin the same crap, and sometimes it's hard to start when it's warm.

give the throttle body a clean out. it fills up with crap from the positive crank vent sys

my car has got the exact opposite problem.
it misfires bad and runs like a pig for the first few minutes of a stone cold start, then will run fine for the rest of the day |

grab a can of crc / carby cleaner etc and spray along the gasket where the intake manifold joins to the head, while its running, if it smooths out, you have a leak on that gasket.
You could also have an ignition issue, dribbling injector, or sensor problem. you just need to isolate one at a time |

whats the best way to check for an ignition issue or dribbling injectors??

I have the exact same problem and all of the above suggestions dont work. Im putting it down to a sticky fuel reg as it appears to be fuel related and its about the only thing that hasnt been changed!
Ive changed fuel filter, injectors, plugs, leads, dizzy cap, rotor button, iat and oxy sensor, fuel pump (old one failed) Tried different isc, map sensor, tps and have put in a better ecu. Its not a vacuum leak on the intake nor is the cat blocked. |

Its on the rear of the injector rail. As far as i know it controls the amount of fuel pumped through the injector depending on the pressure in the fuel rail. I guess if the reg is stuck shut it could actually pump in too much fuel or if its open too much not allow enough for when you put the foot down. Either of these IMo could cause poor idle and performance. I have noticed mine idles rough in cycles when hot. Like the fuel pressure is up and down.
