Hi guys need some help on Ford F150 2007 flex fuel 5.4lts. Bank 1 is dead missed. Can any body help with crank and cams waveform. So far i did test for bank 1 cylinders missed by doing cylinder drop test and confirm that bank 1 is dead. I checked the VCT solenoid on bank 1 and confirm functional as i ground the control wire and there was a tone change the way the engine runs so that tells me that solenoid isn’t stuck. I also took the O2 sensor bank 1/1 and and still dead on bank 1. I was thinking to check for crank and cam sensors signal waveform is my next move. Anybody has a good known wave (cam/crank sensors) form for this particular truck or anybody has idea what to look for. By the way the crank sound test does not sound uniform or good at all. Please i need some input guys. And also i can smell fuel badly and my bank 1 O2 sensor 1 is stuck rich so that tells me that injectors are not intentionally shutting down due to missfires and constantly flooding that CAT. Also I created a vacuum leak and found that all O2’s went very lean so that tells me that O2 sensors are not lying. That is all i got on this truck for now. I’m still thinking that VCT solenoid as i have fault codes PO022 and P0011 and no code for miss fire. I appreciate your help guys. Thank U
