Engine/Transmission (1998.5 - 2002) TST PM3 problems

[CDeklotz]

Guys, i restalled my TST pm3 back in my old truck i sold. The guy who bought my truck wanted it back in there. After i put it back in and drove it, the truck bucks real hard and idles funny after getting out of the throttle while the rpms are dropping. The green fuel light gets darker when adding boost, but i did notice it will sometime blink green when at really low rpms and not even on the throttle. What do you guys think could be the problem. ? Thanks Cole

TST has a test / verification of installation procedure. I would follow it before I drove the truck another millimeter.

Mine did this a few times, sent it back after doing all the test they had on the website, turns out it was a loose connection inside the unit, you might want to also re-check your ground, and check the fuse, even if it looks good replace it, depending on the year truck you can either ground it to the battery for 98. 5-2000, or go to the ground in the VP harness, I think its black with a brown stripe, again check the TST website, also TST has great customer service, goodluck.
