So I've been having this issue lately on and off where the engine looses power. The best way to describe it would be it's like turning off the car except all the electrics, dash, lights and everything else works perfectly it's just the engine cutting out.
I've had it into the mechanics and like usual they couldn't get it to do it. So they have given me the usual check list. Wriggle the loom with the car running and try to cause the problem, change AFM and back the BOV off a bit but I'm still having this issue. The problem is it might not do it for a day or two then just when I begin to think the problem has gone, BAM cuts out again then it will play up every 100m. Sometimes it will only loose power for a split second other time it will do it for a 30 or 40 seconds. It happens any time from being stopped at lights to cruising at 100km/h. Normally it will stall then I will turn it on and it fires fine for maybe .5 of a second then it stalls do that 3 or 4 times till it finally stays running. I have noticed when it has stalled while the revs are still dropping if I hold the accelerator in the boost gauge moves from vacuum to 0 and I can hear a slight sucking noise. I'm not sure if that has any bearing on anything or not but it's about the most I can come with.
The fuel gauge is also playing up which has me thinking maybe there could be an electrical fault in the pump craddle somewhere and the fuel pump is loosing power.
Anyone had this problem before or does anybody have any idea's of what else I could try? It's really doing my head in.
Also the car is relatively stock just has a front facing plenum, front mount, exhaust and boost-T.
Thanks
