At the weekend I had the Intercooler pipe blow off at the top end. There was also a fair amount of smoke from the exhaust.

I replaced the pipe today with a new GM part and the car seemed to be fine again.

travelled 10mls down the road and the car went back into limp mode. Checked the hose again, OK.

reset the codes but engine won’t rev over 3000 revs.

any ideas folks

 

 

 

A friend has just told me that he had exactly the same problem and found that all the exhaust sensors etc. would be contaminated with oil and diesel. He said to run the car and try and burn off the rubbish that was in the sensors.

I did this and as I thought, the Engine light came on again. Plugged in my reader and it didn’t bring up any fault codes.

thought I would erase codes anyway. Engine light went off and car driving as normal now.

everything good, so far.

just done a 12ml trip down the motorway and car never missed a beat.

I hope that’s a good sign.
