2000 Tacoma v6 has has always ran good, but has check engine light code P300 & P306. cly 3 & cly 6 missfire, lean bank 1. Vacuum test showed no problems.
I've changed plugs & wires, switched coils around cleaned mass air flow sensor, checked timing. Ran Seafoam through intake, and gas tank. Check engine light went out for about three miles, then came back on. What else can I do to keep that blinking check engine light off?

Check and clean your injectors. One or more may be partially or completely plugged with deposits.
