Cam bearing caps clean and in the correct order?

So I resolved the issue... Popped the original chip back in and she roared into life

Not quite sure how the chip became damaged but you can see a burn mark on the centre if it

Looks like you've popped it in the wrong way round, usually damages part of the memory which is why it won't be running properly. I can do you a cheap replacement, but am away at the moment - drop us an email.

Thanks to Andy I now have a fresh PPP chip in. Before i swapped cams and chips over car idle was a tad high 1200rpm but nothing ridiculous.

Since swapping everything over the idle has become rough/high when the car gets warm. When i turn it on, its at about 1100 rpm but once the car gets warm it rises to 1800rpm once i apply the clutch. The idle will sometimes drop if i apply the clutch and 1st gear a touch. but mostly it rises back to 1800.

i spent the day going over the diagnostic guide on here, only thing that confuses me is the co pot reading, when i put the multimeter to points 1 and 3 the cars rev drop right down (like its about to stall) and reads a really small resistance. 

when i remove the blue temp sensor at running temp the revs rise, however i realise i didnt set the ignition timing when it was in service mode, will this make much of a difference?

and my cam timing is still half a tooth out.

Thanks

It's essential to set ignition timing in service mode. Do that, and set the CO pot resistance to circa 550ohms as a starting point.

How do i adjust the CO pot resistance?

Measure across pins 1 and 3 after you take the loom clip off, I set mine to 550ohms before it went on a mates exhaust gas analyser. Think he riched it up after changing the blue temp, melted fuel pump relay and lambda

Cheers for that lad, I will set up the timing and resistance and holla back

So I timed it up in service mode. Sounds much better.

When I checked the resistance in the CO pot it was 850, dropped that to 550, although doesn't feel like it's idling quite as smoothly. Should I try increasing to 600/650?

What's your idle speed? Idle switch engaged?

Before I adjusted the CO pot it was 1000rpm. Now it's up to about 1100rpm.

Too high - adjust it down, is the idle switch engaging too?
