I bought a 97 geo tracker 4 cly it has a rough idle but runs good the guy said it just happened while driving, he replacedplugs,wires and cap but not rotor button still no change. Anyone have any ide
Wouldn't hurt to change the distributor rotor for a complete tune up. Is the check engine light on? -Jim
also run a bottle of ZMAX fuel treatment in 5 gallons of gas thur it..and see if it gets any better !!
