Stalling issue - FIXED, YEAY!!!!

(1/11) > >>

Boothy:
Came home from work last night and towards the end of the drive the car jerked badly whilst turning into a junction, almost like a stall. Presumed I must have caught the brake or something and thought no more of it.
 Today however its done it twice again in 4 mile? Once when I dipped the clutch it did stall and had to turn the key again and the second time it just began to stall mid reba then died. I dipped the clutch a bumped it off whilst still moving and it was fine again. No warning lights other than the battery but presumably that's due to the stall?

Going away camping today for the weekend and I don't wanna get stranded. Any ideas? Could it be the battery on its way out? All coil packs were recently replaced too.

Nasir:
The battery lights come on when the car stalls, best to get it scanned for fault codes.

Richn83:
Once the engines running the battery shouldn't be doing anything but charging all electrical requirements should be coming from the alternator so not a battery issue unless you cant start it from cold.

You really could do with a scan to see whats going on.  Also how is your idle is it rough wondering if it could be engine vacuum or something similar.

Boothy:
Scanned the car and its showing no faults whatsoever? Seems to be running ok again now so maybe just some cap in the fuel maybe? Idle is solid.

Boothy:
Done 300 mile this weekend and its still has the same problem? Its always at about 2500rpm and usually under very light loads but other than that it seems totally random. I would guess its done it about 10-15 times over the whole journey.

Its like a misfire but it seems to stall if I'm dipping the clutch to say, change gear or pull up at a junction. Apart from the stalling its very similar to when the coil pack started to go but all four were recently replaced under the recall, along with new plugs at the same time so I just can't see them going in a few months and as I said, no faults have been logged. Other times when I was just coasting at a steady speed with very light throttle I could almost feel the car slowing down, as if I had let of the gas a bit. It very strange.  :sad1:

Not quite sure what to do really as with no faults logged its gonna cost a bomb to diagnose the issue.
