Ok I see why people start getting gray hair.
I have a 2000 Expy EB, 5.4 auto with 113000. I picked it up in August for a song. Now I wonder why. Dealer changed the oil in August. In early November the oil light came on and then it stalled. I got it back to the house , it was 4 quarts low. There is no smoke or visiable leaks. I topped it off and tried to restarted it. It stumbled like a Pats fan on Sunday. It gave PO codes 305, 306, 307 and 357. I replaced the coil on plug and spark plugs, ran a little better. it gives a bank 1 lean on the scanner. I pulled the injectors to clean them. All injectors checked at 15ohm, fuel pressure holds at 28psi on, and 40 psi running.As I cleaned the injectors, 5 of them when cycled with a 9v battery, the cleaning fluid pour out with no resitance. The other 3 dripped when tapped on the inlet orifce. I reinstalled the injector on the same banks but different cyl. It still stumbles/misfires, runs a little better than the last time. I pretty much feel its the injector(s), but do not want to fix it by replacing all the injectors. I cleaned the MAF and ACS, tested the EGR with vaccum guage, DMPS and voltmetered the TPS. I couldnt get the gauge in to do a compression test. I hate in complete testing but, I would like some input on if I should stop and replace the injectors.
