cas which is the crank angle sensor mate...before you change that check that the 2 leds are on in the computer when ignition is turned on if they are on it will be your cas

as well as when a backfire happends it can blow out the wire in your Air Flow Meter(AFM) very small in gauge this wire is..
just run a diagnostic on your system from the ecu to get code numbers..

[GunnyVL]

Also do a check on the power transister the computer doesent list a fault code for it.

[Nackerz]

afm wont cause it to have no spark detox as it would still fire if it didnt have an afm

[detox_nath83]

i know knackers.:P
but as he said backfire its another thing to check now as this can damage the afm

[Nackerz]

Yeah well thats true mate

[detox_nath83]

what they charge for a rebuild kit these days so you can do it yourself?

[Nackerz]

[detox_nath83]
