Hi All,
I'm trying to help troubleshoot a problem with my cousin's car. When cruising at speed (120-140 km/h) it will often start to lose power. The rpm's stay the same, but the car slows down. A downshift and some pumping of the gas pedal eventually clears it up until the next time this happens. He has recently replaced his 02 sensor due to an ecu code. No other codes are stored. I'm ruling out bad gas since he fuels up at different stations. A clogged cat would cause problems all the time. Other than that maybe EGR or timing getting pulled? Anybody experience this type of problem?
Mike
