    ok, i've got trouble. 87 was the first year with tbi right? i've got what could be described as a lope off idle when cold or warm. I guess my question is where should i begin to look for a vaccuum leak? Already did complete tune-up...
    thanks

    Look for a leak at the base of the TBI or maybe between the TBI and the air cleaner housing.
