Intermitent engine cut out

Recommended Posts

Hi I have a intermittent problem with my1987 mk4 xr3i randomly cutting out at junctions or when slowing down. Its the 1.6 MFI engine. Starts fine from cold and when hot. Drives fine on motorway and smaller roads. when its about to cut out the rev counter starts dancing about, you can sometimes keep it running by pumping the throttle but get a couple of backfires, then its fine until next junction. if it does cut out leave it a minute then starts up fine. any ideas?

Cheers Stuart

Hi stu, check the small hoses around the throttle body area for leaks on the joints and splits in the hoses themselves.

Is it just when its really hot?

Could be heat from the distributor effecting the ignition amplifier. Try taking it of and putting heat proof grease on the mating surface.

Cheers

Hi it seemed to be when the weather has been its hottest. The engine temp stays within normal range. Ive got a spare distributor with a new ignition module on, so will give that a go.

Cheers
