Hi
We have a low mileage 207 year 2007 1.4 vti ,car came in non start but it was just upset car started and ran with new plugs in it, test drove 20 miles all ok. Next day customer came back saying he had a misfire read code p1390 cylinder 4 combustion misfire. Wwe replaced coil pack and swapped injector over, road tested same fault came back. Bought timing chain locking kit and checked timing all ok. Removed and sent ecu for testing came back inconclusive,could only test 99% of it.
Checked wiring loom all seems fine, starting to think its ecu but at £600+vat and we don't have auto logic french as yet a big step to take,wonder if anybody as any ideas. when it misfires ecu does stop firing injector.

Sounds like you really need to do some tests and not guess. Have you confirmed ignition using scope? Have you done a vacuum and compression test?

Hi
Car fixed after more testing found misfire jumped to cylinder 3, decided to do a fuel injection inlet manifold clean using our Tunap cleaner, add premium unleaded and car as driven without any issues for 300 miles now, on checking this car was low mileage but driven by older person and had already had a new catalyst and only traveled 40,000 miles.
