Hola,
Having a bit of a mare here...
Bought this back in Sept, had a rough idle, hesitation and a drink problem.
I've put the following on:
After all that, it was still drinking and the idle, while better, was still hunting a bit. I figured the ICV was causing the hunting - it wasn't too bad so I left it. The hesitation was gone and it was accelerating a lot harder.
It's been leaking oil since I got it and I'd been topping it up every so often until I got time to track it down properly. The other week I over filled it - I didn't realise what I had done until I was in a bit of a hurry, the power dropped off and a puff of smoke came out the back. Instantly backed off and all was fine.
...until about a week later when it started to miss. Did a compression test today and I'm getting around 180psi (+/-5psi) on each cylinder - although they took a couple of cranks to get up to 180psi. I forgot to run the fuel out before doing the test so that might be why it didn't go to 180 instantly?
The miss is getting quite bad now but only seems to start when its up to temp and it only happens under load at low revs and the longer it runs, the worse it gets - it'll happily pull from 3500 revs under load tho.
The last time I had this happen (on another car), it was the crank sensor but it made it miss at high revs when hot.
So, given that I've changed everything that matters - bar the fuel pump, filter and injectors - and the head gasket seems fine, anyone got any ideas? I just find it odd that it's only at low revs, under load when hot...

Bought this back in Sept, had a rough idle, hesitation and a drink problem.
I've put the following on:
- New crank sensor
- New MAP / air temp sensor (it's combined on this engine)
- New water temp sensor
- New NGK lambda sensor
- NGK iridium plugs
- Magnecor KV85 leads
- New coil packs
