Could just be fuel trims drive around for a while and see if it maps up and resolves

If not may need to look at fuel/air filter and any pending codes (run and look at codes before turning off as pending ones reset)

Thanks. Problem is car is on a SORN note, no MOT, not insured or taxed. Car was running normally when I drove it back from Chippenham 2 months ago. If you are right it can wait until I need it. I could drive it to MOT station as it is, and I think it should pass.

Car does not start well cold. On third or fourth attempt it starts and runs. It starts hot first time. I wondered if it might be ECU temperature sensor, which I know is fitted in the EGR manifold. I remember refitting it, seemed OK. I have groped around down below the rear of the head, think I felt it, and it was secure. I think there should be an EML on for missing sensor. I thought there should have been an EML on when MAF sensor was unplugged, but there was not. Bulbs are OK.

Sure there are no air leaks?

No, an air leak is my most likely solution. Is there anything I can spray around the inlet system while engine is at idle which will assist me locating a leak? I eliminated the big one, vacuum pipe not fitted. I assume any leak has to be between the MAF sensor and the engine.

With engine running spray carb cleaner around all joints ,,,,air pipes...vacum pipes...manifold..engine...anywhere there is a joint...at which point if the engine runs ok then where ever you are on the engine then thats where your problem air leak would be

Thanks, will do.

Idling hot, I sprayed carb cleaner over the inlet tract, inlet manifold, breather pipes, everywhere i could think of, but the engine note never changed. I have swopped the MAF sensor for a known good one, no change. Might it be the coil stick? Only other thing I can think of is the ECU temperature sensor. I have not changed it but I did unplug it when I removed the head and EGR manifold. I am confident I have replugged it correctly, it is still attached, but with the cam cover on it is difficult to unplug and replug it. Apart from that I have no more ideas.
Of course it might be OK and just in need of a good thrashing. While on a SORN I cannot give it one.Any thoughts?

Book it in for MOT nearby. Then take it out, so if you get stopped can say you are on route

It's not insured either. I could insure it, but as some expense. My plan was to bide my time until another car breaks down.

I wonder at what cost. Thanks Rob, will investigate.

[tunnie]

Been a few years, but day insurance could be had for a tenner 

[05omegav6]

Nearer £25-30 nowadays
