Just put the calibra through an MOT, which it failed!

But when I picked it up the Engine light was on and it was really struggling to start and it is in limp mode.

I had replaced the Lambda sensor and the cam sensor and cleared the faults before the mot it all was well, I did notice when I pulled up at the mot station that it was smoking again at the rear which had stopped after I fitted the Lambda sensor.

Please help as I wanted to go away in it tomorrow if I can get it through the MOT

Have you checked for any fault codes stored on the ECU?

Here's the fault code listings. http://www.topbuzz.co.uk/info/fault_codes/fault_codes.htm#simtec56

 

If you're unsure how to read fault codes on Vauxhall engines, have a look here...

the only 1 got was a crank sensor, which I've been told comes up anyway when the engine aint running, dont get anything will the car is running:(

I've also posted on the calibra and vauxhall forums, but they aint much help

Just make sure you check all the connections. Check the MAF.

all checked, should there be a noticeable change when the maf sensor is disconnected?

Yeah, it'll chug and pop. Disconnect and reconnect. See what happens. Ecotecs were notorious for sensor failures.

I didnt notice any difference when I disconnected it earlier

all vauxhalls suffer from maf probs, even the astra diesel that im using is doing it lol

i was told to pour boiling water over the wire in the maf to clean it, but im dubious to try that lol
