I have a 1994 GMC Sierra 4.3 liter V6 that slowly quit running while driving today.It will fire up if I disconnect the MAP sensor but not smooth enough to move it. Any ideas would be appreciated.

Replace the Ignition Control Module (ICM), BWD CBE28Z, $43.99, Advance Auto Parts, Lifetime Warranty.

Thanks to TxGreaseMonkey for such a prompt answer. I will let you know if it worked
