[Mk2] [Turbo] Spluttering in the morning then clears up? Any ideas?

[djpkins]

See what you mean...rev 2 are very intollerant of any kind of air leaks...

I think its damp inside the ignitor (or was it coil )that causes this.

It's had lambda sensor, plugs, leads, coil, igniter, dis cap, rotor arm, coolant temp sensor, main earth under inlet removed and cleaned, map sensor pipe put back to original and I sourced a new feed from end of the inlet manifold for my boost sensor and gauge.

Might be worth disconnecting the battery for a while to totally reset the ECU if you haven't tried this already. Could also be worth trying another ECU as well and seeing if that helps.

[Bone]

I bled the coolant system and still no change. Its missing on idle when cold now. Fine once warm.

[djpkins]

Man....I'm feeling your pain on this one mate...it's has to be electrical, I doubt very much if it's ECU related...would the DP possibly be snagging the wastegate and not shutting it propperly untill it's warmed up, expanded a bit and allowed it to close...
You've replaced everything electrical from dizzy to plugs...did you test the coil against the specs in the bgb...
You replaced the water temp sensor...What about the AIT sensor.

[Bone]

It's definitely not the downpipe or wastegate as I know that's all fine cold or hot. I didn't test the coil because it was brand new. I haven't replaced the air temp sensor as of what Paul said in an earlier post. Going to do a compression test friday and check my timing.

Running out of things to check now

[Chr15py]

How long ago did you replace the coil etc?

[Bone]

3 weeks ago.

if your timing was out...your timing would be out all the time...i was advised about this when i had similar woes.
you haven't tried to mess with the tickover rate by adjusting that small screw on the the TB have you or replaced the throttle position switch and not re calibrated....TBH a compression test sounds like a good idea, and I really hope that its not that and you get good readings across the pots.
A spraying of fairy liquid/water would show up any air leaks in the pipework and cost nothing/ easy to do.
Another thing that I checked when having probs was all the splice connectors that I used to chop into the loom for avcr etc...just making sure that they wern't touching the body work or getting damp, cos the boot is a very leaky area.

I'll check it anyway. No I haven't messed with anything. The throttle position sensor is untouched. Pipes seam OK but will give them a squirt and all of my wiring is fine. I'll do the compression test on friday and see how that goes.

[mrdb]

ignitor could be the cause also...

Been changed

I'm gonna keep an eye on this as i've got a similar (ish) problem. Not meaning to hijack, but mine (now rev3) has a slight misfire when cold and chucks out loads of grey smoke that stinks of fuel, but the misfire doesn't clear when warm - although the smoke does.

It got so bad the other day that it sounded like it'd dropped a cylinder, like a scooby ! I had to pull over as it was undriveable but seemed to clear a bit after a couple of mins idling.

Mine is definately not right so i'll be intrigued to find out what your issue is. I've fitted new plugs, leads, dizzy cap and rotor arm.

I hope you get it sorted bud, if I figure mine out - i'll let you know

So do I mate. Hope you sort yours too. Cheers man

[djpkins]

another thought here guys...have you checked your dizzy oil seal for leakage into the unit?

[Bone]

It's clean and bone dry inside the distributor cap.

[djpkins]

Mine was leaking cos you could see it dripping a bit underneath...Skywalker advised me to renew the seal, which i have but I couldn't see any sign of oil in the cap itself...not sure if affected running though.

o-ring 90099-14090 is the part number but it's only an o-ring thats 3mm thick and 27mm across.

Have you removed the charcoal cannister?

[djpkins]

lololol....going by the amount of people who've read this thread, it's a common prob.
