I have a 1995 monte carlo with 70,000 miles on it. It smokes out the back near fire wall,also the service engine light is on
The 1995 monte carlo LS smokes out the back near the firewall,when i drove up to 50 mph
it would hesitate. We replaced the spark plugs, the wires,coil packs,TPS sensor,EGR
valve,oil change,camshaft sensor and camcrank crankshaft seal and it still smokes out
back,cant seem to locate where.
