and to finish it all off (face it, ME clean the car???), I tackled the ICV and TPS after work this evening. See, if I do work like that then I've earned my kebab meat & chips (with chilli and mint sauces. mmmmm)...
Bit of a pain in the arse I must say - MUCH easier to do on the tubby. To get the ICV off I had to take the airbox top and rubber hose off, because the pipe was too inflexible. Then to increase the fun, to get to the bottom torx screw on the TPS you need to separate the throttle body from the inlet manifold! Didn't realise there's a gasket there, so I'm going to have to redo it soon I think.
Then (of course) I put it all back together only to find the car idling at 2000rpm and taking about 10 seconds to return there from 4000rpm

Took a while (and an ECU reset) before I actually thought about it and realised I must have buggered the TPS. Thankfully I'd just not clipped the connector back on properly
Got it on the road for a spin, worked up through to 5th without touching the accelerator - NICE, rock solid idle - NICE, held it on a hill just using the clutch with rock solid revs - NICE and of course that 0 to lots acceleration you only seem to get with an ECU reset - NIIIIICE
Yeah, the pipes were a lot bigger than I thought too, so I need to get some jubilee clips on there when I get the gasket. Also the TPS may need replacing soon. It's sealed with some sort of epoxy so I just sprayed contact cleaner at a few tiny holes and turned it for a few mins until it smelt dryish. Probably asking for corrosion doing that
Interestingly, there's a small pipe going into the underside of the rubber air hose between the air box and throttle body. It just went towards the engine block somewhere and when I dismantled it, it wasn't connected. It was a push fit with a plastic clip holding it on. Anyhow, I've reconnected it but does anyone know what is it supposed to be?
<steve_earwig> I think this forum is more about keeping our cars going with minimal outlay than giving our cars more reason to go bang
