hi everyone
i have a 172 on 42K which has just developed starting problems, the engine feels very lumpy when idling. it is idling at around 650rpm and is misfiring a bit, also there is a flat spot until the engine in warm. i have changed the usual suspects air filter element, spark plugs, new stainless steel exhausts system (cat back) as the baffles had gone. i have had 2 dianostic tests from renault specialists but no faults were found!
the funny thing is it runs and performs well the only time it doesnt start is if its left over night however if you turn the ignition on so that the dash lights come on, then turn it off then on again it starts instantly!!
can anyone help me please!!
the only suggestion one garage gave me was it could be a problem with the vvt campulley
timing out ? what do you think?
