ok i have a 98 ford f150 v6 4.2 and it is still missing after new spark plug wires and spark plugs, air filter, fuel filter, ECT senser, and a idol control valve and i checked for leaks and there was none i had codes ran and its throwing lean codes

 

Coil????

 

well see it has a spark i checkd that to but if it was the coil wouldnt it throw all banks on lean cause i just had banks one and two throwing lean codes

 

or could it be my pcv elbow hose
