Alight. voltage tested 12.4 off and 14 even running, changed out injector #4, fuel pressure is good (at idle anyway), maf and air filter have been cleaned and she's still reading lean. the Wideband is only a week old and I tested the sensor already. I'm at a complete loss now. about to go grab another set of TR55s and throw one of my other wallies in the tank and see if maybe that's the issue. Is there any way this could be an ECU issue caused by the power loss?
