Hi guys, the last few weeks when stoped at a corner and going slow out of a corner my engine cuts out and the steering and brakes go hard. The battery light comes on and the car wont start straight away. The cd player, air con and power windows still work. Its only since i had a Mafless tune. It only happens once a week. It pretty dangerous when cars are right up your arse and going across a intersection. The cars a VY SS.

Went back to the tuner today and he connected the laptop up and he couldnt find anything wrong. He said everything seems to be running fine. No errors came up, but he said it sounds like it is electrical.
On the way home from work it done it twice and i almost had a very bad accident with a truck.
Anyone else know what it could be.

Just because the tuner says it isnt related to something he did, if your car was fine before that Id still be on his case.

It could be anything causing it. There is more than likely some error codes. If the engine just stalls and wont restart straight away you can bet it has generated a log.

It could be a little glitch in his idling maps or anything.

I recon go to your local GM dealer and ask them to Tech II the codes for you then go to the tuner armed with this information.

The guy who tuned it wouldn't be lying about no codes.
I had the same problem and no codes showing up, crank angle sensor was changed and hasnt happened in probley 9 months.
Sensor would overheat and cause the car to stall.

probably is something to do with the tune, but first thing first man take the car off the road before you get injured.
