first off a little history. the truck (85 toy pickup 22r) was originally from colorado (high altitude version or whatever) came to vermont and my buddy picked it up for free. at 1/3 throttle it would climb to about the right rpm then it would cut out for a second and then it would catch and climb back up then cut out again. from 1/3 to about 2/3 it would run better but it still wasn't quite up to parr. well the engine blew in that so we took the engine and tranny from my truck (85 pickup 22r from around here) cause my frame broke in half :mad3: and put it in. we desmoged it completely (pluged off about 13 vacume lines) and started it up. it idles great but around 1/3 throttle it does the same thing as the old engine and carb with all the smog. anyone have any ideas? could it be something to do with the computer? sorry about the long post.
