Got a problem with an 04 plate 1.2 Clio, I took the engine out and replaced the clutch. Seems excessive I know but I didn't want to faff around on the floor with the subframe ect. Anyway, got it all fitted back fine and now when the engine is cold it runs really rough, not misfiring just lumpy, runs perfect when it's warm so replaced the coolant temp sensor and it's still the same. Couldn't find any air leaks and there's no lights on the dash. But, if I disconnect the iat

 

sensor it doesn't change the running? Any thoughts of what it could be?

 

have you got all the earths back on?

Any vac pipes that could have been mixed up?

 

I'm pretty sure all the earths are on, and it has no vac pipes on it. There's a few breather pipes and that's it. I'll double check the earths again.

 

i would think you got something wrong if it was right before? and you do know you can just dop sebframe on one side?

 

I didn't know that no, i hate working on French cars! Could the intake air temp sensor cause crap cold running?

 

you need to plug it in and take some live readings to pinpoint it, guesing will not work matey.

 

I'm awaiting for my mate to give my obd reader back so I can plug it in, just wonderd if anyone had any similar issues.
