Hi everyone.

After replacing a broken rocker and refitting the head (mechanic did all this), my car is shaking at idle. As soon as the accelerator pedal is depressed - ever so slightly, just past the 'click' of the TPS - she runs fine. What the hell is wrong?!

I've checked the ICV. Tested connections and terminals according to Bentley. Volts on connector are a bit off, but not by much.

The blue temperature sensor's resistance seems fine.

Can't find any air leaks at the usual places (cracked boot etc.).

HELP! At last I have my baby back and she's all jittery!

spray some WD40 or carb cleaner around the inlet manifold where it bolts to the head whilst the car is running, if a steady idle is temporarily restored then there is a problem with either the inlet not being fully tightened up or the gasket is duff.
