I have a Renault Clio 1.2 16v extreme car that is having this problem with loss of power and warning light and when I turn off the car and on again the warning light disappears but my engine management light remains on. I took the car to the garage and they replaced the
and cleaned out the
and checked the wiring loom and did not find any fault on the wiring loom. After doing this the warning light still comes on and I loose acceleration and this is really dangerous when I am on the motorway. Is there anything else I could get the garage to do to try and solve this annoying problem.
