hi my 2003 clio dci 80 when cold searches at idle and has stalled when initially started in the morning but fired up straight away second time and does not stall again.

once warmed threw and run for a few minutes it is ok any ideas?

ive serviced the vehicle to see if this helped but no joy all filters oil/air/fuel and engine oil was changed

also i own a clio dci 60 and would like to up rate the engine to 80 can any body tell me the differances between the engines ive read that the only differences is a intercooler and ecu map?

thank you jamie
