Asked by Mar 25, 2015 at 06:01 PM about the 1994 Jeep Grand Cherokee Laredo

Question type: Maintenance & Repair

1 Answer

735

Could be a few problems from bad plug wires to a mass air flow sensor to just a broken vacuum line. I would start with checking all the wires on the sensors under the hood, then looking for broken vacuum lines before you spend any money on parts. Just a loose or broken vacuum line can cause all kinds of run problems
