jabba sport strikes again .. :rolleye:

jamiep91:
It was a revo on there before done by amd Essex , I don't have a printout for anyone to look at as they still haven't supplied one , I'm really p****d off .

I changed the plugs and it was still there and while jabbasport had it they swapped the coils round and it was in cylinder 2 all the time apparently so not the coils. I needed the car at the time and they had it 2 days so I couldn't leave it there again. I think I will be taking a trip there Saturday.
Yes it has a uprated hpfp but I have tested the DV yet as I'm not sure how .

Is there something in the inlet manifold that can stick from carbon build up or is that somewhere ?
Thanks

Hedge:
So they took Revo off and put one of their own efforts on.  :stupid:

At least go back and get them to flash it back to stock so as you can get your Revo reapplied.

Get somewhere that knows what they are doing to look at it.

Andy:
ask for a refund as it didn't cure your problem like they advised it would

Hurdy:

^^^^^This^^^^^

If you have checked out the coilpacks and spark plugs then the next port of call are the injectors. Are you sure they are S3 injectors? I've seen a car with a K04 upgrade and when the injectors were taken out they were stock K03 ones. If they are S3 injectors then swap the one out of number two for a new one. If it cures it I'd suggest taking the head out and inspecting the piston. I've also seen the damage a faulty injector can do to a piston. Before this you could have a leak down test to see if you are losing compression too. This would show if the valves aren't seating correctly through carbon build up and it isn't a hard test to do.

It is all a bit of a bind, but will pay off in the end.
