So I bought a used TST. It's an older one that did not have a controller. It was off of a 99 so I bought an 02 map plug for my truck. I wired it in using posi-taps(pump tap, 12v power supply). I start the truck it has a miss. I whack the pedal to bring the rpms up to 1200. The truck goes back to an idle but it's idling 100 rpms higher and missing. I play with the throttle and is misses and different rpms also. Fuel light is blinking on the box. I've checked connections 3 times. All looks good. Fuel pressure is good. What could be the issue ? I also have a smarty on it at level 5. It's a 6 speed so it has the HO pump. Any ideas. Looked at some threads from a google search. Nothing concrete. I turn the TST off no miss.
