A9L reading constant 150 coolant temp with good sensor
just like the title says.. I have a 90 foxbody with h/c/i and I cant tune the damn thing because the computer is constantly seeing 150 degree engine temp. I know this is the default setting for a faulty coolant temp switch, but I have verified that the switch is not faulty with an ohm meter.
its a 306 with 11r 190s, tf stage 2 cam, street heat intake, 30lb injectors, long tubes, egr delete.. tuning with a quarter horse. Had it running good when hooked to the quarter horse, burnt a chip and it runs rich and wont idle for crap.
