Fitted the williams engine to my 19 16v and started up yesterday .
without the throttle cable even fitted she starts up and reaches 2000rpm straight away then starts creeping up to 3-3.5k rpm gradually ,the engine will thankfuly die if i block the icv which means there is not a leak on the inlet manifold etc .
it feels almost like the ICV is being opened further more as the engine keeps sucking .
I have tried 3 different icvs and the result is the same . i checked the icv wiring which seems to be fine but having no idea what the measurements have to be i could not check all 3 connectors with a multimeter .
However the icv is being primed when the ignition is turned on .
Also suspect the ecu , which is fitted with a chip carrier and is currently holding a summeh 180 chip in there .
I have changed 2 throttle bodies again there is no difference .
anyone experienced similar before ??
I know it will turn out to be something really simple and stupid
Next on cards is to swap the ecu with the one from my R9
on monday but till then please fire away da ideas :P
