Re: Need Bosch MAF for 86 TA TPI 5 liter

Too much. Delete that junk and go to speed density. Either with a 7730 or a stand-alone engine management. No reason ON EARTH to keep the MAF.

Actually they are quite common. You haven't heard of the Toyota recalls related to the air injection valves obviously. All the modern air injection systems use electric pumps.

Do you have 5v at the MAP sensor? Should be on the same 5v supply from the ECM. There are no fuses - circuit protection is provided by the ECM itself.
