engine swap - runs, but not good-HELP!

[blk88lx]

just did an engine swap on my buddy's 88 LX. It was my old car and someone had put in a crappy speed density non-HO Tbird motor in it. We swapped in the motor out of my 93 into the 88. Its a stock HO, 70K, ran great. Did not change anything else except the computer.

Problem - car wont start unless I give it gas, like a carbed car.
Problem - runs rough, motor shakes, won't idle unless gas pedal is pressed.
Problem - gey smoke out the pipes, lots of it.

b4 the bird motor, it had an 88 speed density HO in it so I used that computer

The MAP sensor had a vac tub going to an outlet in the upper intake on the T-bird motor. My 93 never had a vac tube coming off the MAP. The outlet on the upper is blocked off and that's how I left it. I plugged the 88's MAP tube w/a screw.

Car will run at higher idle but smokes.
HELP!
