Maff issues Ok here whats going on. Working on a 98 T/A Now for some reason the maff does not work at all, codes are throwing and on my Tech 2 is doesn't move. I swapped maffs for working one and no difference. It has 5 volts to the plug, signal wire from the plug to the ECU is good, and soo is the ground. I don't know what i am missing here.
Now here is the weird part. If i have the key on engine off, and pull up my tech 2 and look at the TSP %. Ok now as soon as i touch the gas and hit 1% the LTFT bank 1 goes from 0 to +25 with the engine off?? How is the possible? lol
Anyone have a logical explanation for that one.
