1999 Galant idles ok, jerks and bucks while driving under power


Asked by Jul 22, 2013 at 01:24 AM about the 1999 Mitsubishi Galant

Question type: Maintenance & Repair

When the car is idling stopped, it idles fairly decent.  When the car is out on the road, it jerks and bucks and threatens to die out.  Driving slow, the problem is still present, but to a lesser degree.

sounds like an O2 sensor but could be something else ,,, you get any CELs ? (check engine lights)

Check your fuel filter then pump;)

Could be the crank sensor/ cam sensor may try those.

It could be EGR valve or map sensor or MAF sensor
