My engine seems to miss or cut out when I am driving and accelerate. I put in new plugs and wires and did not help problem. Have also put in a new fuel filter and srtill have a problem.
It will sometimes drop me out of cruise control when It is engaged.

U should check and see if u maybe cracked one of the plugs and gap them all correctly at.040" gap. Also are all the wires routed right?On those cars the coil towers are known for turning white from corrosion causing missing even with new wires if not cleaned properly and sometimes u need to replace the coils if there corroded too badly. Also the coolant temp sensor on those are known to go bad and cause erratic idle surging cutting out. Its screwed into the head bellow where the upper hose hooks on. Its small and has two wires goinng to it when its cold squeze the connector it should release look at the connector if its green inside it is corroding and needs to be clean some how or replaced the sensors crack on the side that screws into head lets coolant into the connector.U can also unscrew it and see if its cracked the sensor that is make sure its cold and u will lose coolant so be ready for that. Let me know what u find.
