2.2liter car starts but pulsates when it runs after it warms up it quits running and won,t start until it cools off.
Check all of your connections at the coil pack. Ensure that the coil packs do not have any corrosion under them were they connect into the base module or any of the connections, even plug wires. I had this same problem with my 2.2 in a 99' s-10. Pulled the coil apart, cleaned it up and and put di-electric grease on it, all better.
