E30 Zone

Right, I've cleaned the ICV, removed, cleaned, and reset the (filthy) TPV (which passes the multimeter test), changed the plugs, and run a bottle of injector cleaner through.

Basic cold starting is still a lot better, but I'm still getting the following symptoms:

• Poor cold starting if it's been raining
• Really rough idle once started while cold (much smoother once warm)
• Exhaust often smells of petrol during cold idle
• Exhaust sometimes smells of petrol even during warm idle, after a drive
• Very unhappy to cruise along in gear at lowish revs without throttle - when most cars would just gently engine brake, it starts to kangaroo
• When I press the thottle from idle, it struggles momentarily, before picking up the revs
• Generally quite poor low-down torque, and unhappy low down - needs a lot more revs than I'd expect to move off
• Poorer MPG than I'd like - ~24mpg mixed, ~27-8 on longer steady journeys

I know that the ECU is designed to richen the mix when cold, but I wonder if it's doing it too much? Might an over-rich mix low down all the time might explain a lot of this? (BTW, the mix higher up is OK, as I've tested it on a motorway run with a wide-band lambda kit.)

I'll try and take it for a slower drive with the wide-band attached this weekend, and see what this shows lower down. In the meantime... any ideas?

Thanks

hmmmz

blue temp sensor??

check the rotor and cap, possible worn / bad contacts. (at least remove and take some emerypaper over the contacts.)

Air Leak??

Check the injector wiring under the inlet manifold, this could be so many things. Good luck!

how are the plugs...

I've been having a few of the same problems with mine.

missfires when first started but fine when warm.
exhuast smells very strongly of petrol at all times.
and i get the kangaroo problem aswell.

my mpg is about 15 round town but will do about 35-40 on a motorway run.

I was told it could be a maf problem.

Thanks for the suggestions guys

• Blue temp sensor: I've not checked it. Can it be checked, or is it just something to replace? Will search...
• Rotor and cap: on the to-do (and to-search!) list.
• Air leak: I've not seen an obvious air leak, and have had the MAF-TB trunk off a couple of times. I'll have a closer look everywhere else. Gaskets are on the to-do list...
• Injector wiring: what am I looking for? Just obvious damage, or do I need to get busy with a multimeter?
• Plugs: I've not checked the new set yet, as I wanted to give them a couple of tanks before looking. Will do, and report back.
• MAF: not cleaned yet. Will do.

Looks like a busy Sunday...
