    Okay been workin on my truck went from 5 different cel codes to two one problem though. the ESC has failed and everyone says its on the black bracket next to the tbi. very funny. its not there. can somebody tell me where shes at. is it next to the computer under the dash, hiding here or there. please help ive got the part already and the low rpm slowdown/stalling is getting old. any info is greatly appreciated. if someone has a picture of the location a schematic or something. all i know is it is saying a code 42 and 43 a timing error and a esc failure. causing a timing.Thanks

    ESC, in laymans is called the Ignition control module. and it is under the distributor cap, with two bolts holding it down.

    See i have heard both, and with your truck (1994) the ESC is in the computer, the older ones did as well from what i understand (ive had 6 1988-1994 Trucks) however im not an expert to be honest, and the ESC really was new to me till recently.
