Engine Performance problem
2002 Volvo Wagon 6 cyl Two Wheel Drive Automatic 66493 miles
Every cold start engine hesitates/surges, backfires if accelerated. After warming up the engine, temperature at half on gauge, no more problem. I have cleaned the electronic throttle body, the CVVT solenoid. Checked the ECT all normal. What can be the problem?
