Hi All

I've just picked up a cheap 1.8L Cordoba for my brother but it has a small issue in that it starts and runs fine but if you give it a boot load of throttle (as in full throttle) it bogs down and back fires through the throttle body.

I've only just picked it up and swapped the fuel pump and installed a new battery and a part from getting it running I've not yet had time to fully diagnose the problem.
I'm thinking it could be a lean fuelling issue (vacuum leak?) or bad ignition timing.

As I don't (yet) have an OBD error code scanner I can't check for error codes - any suggestions would be greatly appreciated.

Chris
