right then,
when my cars running and the engine is cold it runs perfectly and ticks over at 1000rpm..
when it gets hot (after about 15mins) the revs drop to about 500 and then generally runs very lumpy and stalls all the time!!
has any one got any ideas to what the problem could be???
any info/help is appreciated..

Maybe the Idle Speed Control Valve needs cleaning?

i will have to have a look at the idle speed contol valve,
i dont think it has an air leak as it has all new pipe work.. it was doing it before i changed the head yesterday, and still doing it now!!??

hi m8, if the cars chipped make sure its in the ECU properly, if its not you will get a problem like this, i put a chip in mine, and in the instructions it said put gaffer tape over the chip to hold it in, i didn't cos i thought it would be okay, of course im washing the car with it running and noticed it started to run lumpy, then 5 mins later it cut out, looked under the dash and the chip had fell out. Of course this only applies if its chipped.

nah its not chipped yet??

defo check idle valve then, do you know if you have the maintence free idle valve found on later 2i's and RST, normally H Reg onwards.

Have a compression test done - you may find ure hg is gone (note you don't always get mayo).

After that, check your leads for breakdown under heat.

Defo check how clean ure iscv is inside.

Sounds more like a sensor failure to me though - maybe one of the ECU's temp sensors?

i changed the head and fitted a competition head gasket on saturday, so cant be that..
and i have brand new plugs and leads fitted..
are the ecu temp sensors in the ecu or not??
