Technical poor running when engine is warm.

[jacko-27]

hi, i've not long had a bravo 1.6 16v 100, and i've just replaced an injector for it, but now when the engine gets upto temperature and the auto-choke changes the fuel/air mixture, the engine starts running poorly, but runs perfect up until this point. Any help would be much appreciated - thanks.

definately sounds like the lambda sensor. they often fail when you have a faulty injector, and your symptoms are typical of lambda failure. you should change the plug and lead on the cylinder that had the injector failure because the plug and lead will almost certianly be 'cooked' from running dry (change all plugs and leads).

Thanks jug, i'll try replacing the lambda sensor, plugs and leads. The only other thing i was wondering was if it could have anything to do with the knock sensor, as this was a fault that also came up when using a diagnostic machine when i replaced the injector.

yes it definately could. thats always my next suggestion in this situation
