ok 12 & 55 are nothing
12 = battery was disconnected
55 = end of codes
now the real problem codes
13* MAP sensor or vacuum line may not be working
24* Throttle position sensor over 4.96V
(SEE NOTE #3)
NOTE #3.
Matt Rowe: “The throttle postion circuit tells the computer how far the accelerator is depressed. The Throttle Position Sensor (TPS) is on the throttle body on the opposite side of the throttle cable. The connector should have a round rubber cover over the connections. Clear the fault codes, start the car and try jiggling the wires/connectors to try to trip a fault code. Loss of this signal could cause other problems.”
Tom Wand: “Throttle Position Sensors (TPS) will on some early 1990s trucks start to drift high in voltage, there was a problem with these and the idle will not set low enough. Need to replace if it does this. As I recall, the output voltage at idle is 2.4 volts, much above is no good.”

TPS MOD-
Make a slight mark on your TPS and TB to line them up before
removal
Remove your TPS from TB and drill out the 2 brass sleeves where
the screws go through the TPS....you will need 2 small washers
to to place on your screws to reinstall the TPS.
Install your TPS with the screws and washers, line up your marks
you made earlier....but dont tighten them all the way!!
With IGN on, check the voltage at TPS (i think orange and black
wire center wire) The voltage should be .68 - .75 volts, if its not,
you can move the TPS carefully and you will notice that the
voltage will rise or decrease....set it to .7volts and carefully
tighten the screws making sure the voltage doesnt rise or
decrease. That should eliminate your TPS probs....
