Recently my van will misfire under load (while accelerating quickly). My check engine light has been on for q couple of months and I think my O2 sensor is needing replaced. What will cause the misfire?

Scan for codes and check fuelpressure first. You have to know the code before attempting to replace parts.

I had the codes scanned and found out that one of the coil packs was going out. Will get that replaced ($80) and get an air and fuel filter while I'm at it along with a complete tune up. : -)
