thanks,
yes it has a S4 engine with a S5 intake.
the car starts and runs fine but shuts down after a few minuets, with no spark to the leading coils. there is a signal coming to the coil from the computer but the coil wont fire, i assume the leading coil has bad igniters.

i have a new leading coil on the way, until it gets here i'm willing to negotiate the price.
