I have a 1987 Cherokee Pioneer with a 4.0L MPI and am having injector problems. We recently had a rebuilt engine installed and they messed up the injector order. I have a Chilton and the wire colors do not match. It dose run but rough and black smoke from the exhaust :banghead: I have new injectors to install but I am uncertain of the injector wire order.
