Just fitted a new exhaust to my wagon to do so I had to take the intercooler off so I did so put it all back now the car is really lumpy on start up and idle and cuts out after about 5 seconds

 

Full exhaust? What did you do about O2 and lambda sensors?

 

Yeah full turbo back, and I made sure the sensors were back in, when I touched the sensor on the induction pipe the car idled normal for a second or two then went back to lumpy.... thanks for the help

 

Duff connection, or damaged sensor.

 

Sorted!!! After seeing your message I went out to the car MAF sensor wasn't all the way home looked it though, I'm an electrician aswell

 

Easy done.

My eldest had a new manifold fitted to a Clio 197 by a self styled Renault Sport specialist in Doncaster.

They knackered the Lambda connection and glued it back together. When it ran like a bag of nails they couldn't find the fault. It had to go to RS Tuning in Leeds for that...and a further £250.

Yet my local garage man, on being told the symptoms, said, "Lambda duff or disconnected|".
