I am currently working on my little 3.1 v6 and think I mite need a ECM . what other vehicles use the same ecm? I'm thinking any GM vehicle with a 3.1 or 3.4 with MPFI should work ?? I would like to pull one from the U-Pull-it for $10 bucks and see if cures my problem.
thanks in advance

 

The ECM are similiar but you will definetely need the appropriate MEMCAL chip for your particular car.
