for some reason ive got nothing on 2nd pot ive checked it's got spark at the plug and ive tryed changing the injector but it's still the same. ive took the head off thinking it's a bent exhaslt valve but pot 2 is alot cleaner than the other 3 like it's been flooding has anyone esle had this problem could it be an ecu fault sending to much petrol into the pot

 

check the wiring to the injector mate, could be broken inside the insulation so check for continuity between the pug end and the ecu plug end with a voltmeter
