P0236 and P0237 with very sluggish throttle
Truck threw a P0237 and P0236 and started having very sluggish throttle with no fuel available. Figured it was the Map since that was how it reacted the last time the map failed but even with a new map and iat and cleaning all connections from the TST and EZ and trying the truck without both and with each separately it just won't straighten out. Starting to think it's maybe the APPS or VP44 but it's odd that I have the 2 MAP trouble codes.

After some more experiementing the truck runs fine with no codes if I hook up the truck directly to the map sensor. The problem is only apparent if I hook either box up. Guess it's time to pull both wiring harnesses and see where the problem is. Might just order a new harness for the TST.
