Sounds like a dirty mass air flow sensor but the hill thing is strange...Is the tank full when this happens? Could be a filter and would not hurt to change it (often neglected).

I have a 1.6 auto petrol renault modus reg55.After I turn on the engine if I push a hard break the rev falling down and the engine stop.But only at the first few miles. Any idea for this problem? Thanks


reg codes only work in UK, use real years..... so ROTW can tell.
please, tell what it does good and bad driving, idling , parked, moviing
hot and cold engine, full power from engine on hills.
stalling (it stalls) but when does it stall, under what conditions. hot or cold engine. only at stop lights hot. or>????
when an engine is cold the RPM is very high (iAC device) and it will not stall cold , if it does that is key.
if it never stalls hot. and runs perfect hot say so.
all these, clues build evidence. to what is wrong.
then we do tests.
PS: ever think to get that 60,000 mile (100km) tuneup>> now be it.

check crankshaft and camshaft sensors. If faulty they may cause misfires, poor fuel mileage, stalls, hard starts. Make sure the ignition coil is ok, including its powers circuit. hopefully this helps!!

Have you replaced the timing belt? if not i would highly recommend doing so. these cars need to have the timing belt replaced before it breaks otherwise it can and will cause major engine damage.
