Engine Performance problem
2002 Mazda b3000 6 cyl Two Wheel Drive Automatic 74,900 miles
i have a 2002 mazda b3000. After about 45 minutes of highway travel at 60-70 mph, when I stop, the oil guage bounces until I press the gas pedal again. Its only after kind of long trips. Short stop and go trips the guage is fine. What is wrong with this?
