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 ch...

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

I think its damp inside the ignitor (or was it coil :lol: )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 ...

Yeah I've got a berk downpipe. I have got a very slight blow at the moment. I've just changed the turbo to downpipe gasket and there's still a leak. I'll have to investigate further. I can't see it effecting it much because my old downpipe cracked 3/4 of the way round and it still ran ok.

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. Tomorrow I'm going to bleed the coolan...

Did yours pop and bang, misfire or did it just run lumpy?

It's had a new coolant temp sensor and a new coil. It's doing my nut in

Right Paul, I've sorted the map sensor connection, removed and cleaned the earth on the inlet manifold and there are no error codes. Still got the problem when cold and its fine once warm. Any other ideas? Cheers.

Cool cheers mate.

What does the filter look like? Not sure if ive got one. I've got a boost gauge and a boost sensor tee'd off the map sensor pipe! I will get the feed from else where now. I think I've fixed my problem but I need to use the car for a few more days to be sure. It was the plug that goes on the coolant ...

Got some bad news, the problems back. I'll explain what's happened... Original problem was only when cold then ran fine once warmed up. Then it started doing it really bad all the time regarding the temperature. It showed error code 21 (lambda sensor). Right some progress, I checked out the lambda s...

Cars sorted! It was the lambda sensor lead shorting out! Who ever connected it in the past only used tape to cover the elecrical connections, the tape melted which caused it to short out. She's running perfect now.

Thank you and merry Christmas! I'll have a look at those things over the next few days

As subject

Any help will be great. It's a rev 3 turbo. Thank you.

I've replaced plugs, leads, cap and arm, igniter, coil, coolant temp sensor.

The thermostats not very old and it does it even with the heaters off.

Well I changed the sensor and it did sort it or so I thought. Its loads better but just recently its started to do it again but not as bad and not all the time. Air temp sensor next?
