Vs Commodore Cutting out while driving

[brianthedigger]

Hey,Just wondering if anyone can help me out,I've just had my front engine mounts done,ever since then my car has lost power and feels sluggish and once it warms up it is cutting out while i am driving,but it starts up with no problem.I've taken it to a auto electrician and he said everything was good.I had the crank angle sensor replaced about a year and a half ago.Also wondering can incorrect tension on the drive belt cause this to happen because when i got my engine mounts done since then i have a noise coming from my tension idler pulley and i read in a vs manual that this can cause overheating etc(its been running a bit warm but not overheating).was thinking the mechanic might of not have put the belt back on at the right tension.Any help would be great thanks

If the Belt is nice and tight, then there shouldn't be any problems there. When you are turn your car to the on position can you hear the fuel pump prime? There could be a slight blockage somewhere... Might need your injectors cleaning. I would also look at your Ignition coils and DFI module (The plate that the Ignition coils sit on). Have you checked your Spark Plugs? Also your spark plug leads?

First thing you need to do is to check for error codes - I've given the link below and it's very easy to do. Serpentine belts rarely slip as they are toothed - a creak every now and then from the tensioner pulley is OK as it's usually the spring inside the ensioner creaking.

You can't adjust the tension of the belt (it's self-adjusting) and the reason a faulty/slipping belt will cause overheating is because it also drives the water pump pulley and won't be able to drive it properly.

yeah in the end it turned out to be the crank angle sensor,must of got a dud one last time.Thanks for your help
