Overfuelling Hot CAT Warning
Hi
Been ongoing for a while this, seems to have changed slightly but this is the latest
On putting the clutch in on driving, my Subaru Impreza (95 WRX import) lets off a decent bang from fuel in the exhaust.
In the wet and when the car is stone cold, it can splutter like its running out of fuel, and the hot CAT warning flashes on the dash.
Drove abit lumpy this morning aswell, seems to be an ignite/fuelling issue.
I have cleaned out the ICV, replaced the crank shaft sensor, re-set the ECU, no fault codes, cleaned sensors, had new plugs on last year.
Fuel pump seems to prime ok, all these issues seem fuel related, could it be the coil packs, how are they tested, or any other suggestions?
Thanks
