rpm not stable
Posted: Tue Mar 29, 2016 5:41 pm
i recently bought a used honda airwave 2007. it has a problem with the rpm. sometimes when accelerating rpm holds on 2000 for few seconds and suddenly release and rpm reach to 3000 car jerks and comes back to normal and again. sometimes gears will not shift till rpm reaches to 3000-3500 and even worse sometimes 'D' start blinking and losses power. and at the speed approximately 50-70 rpm is not stable. it goes up and down continuously. but at the highway all seems ok.
to resolve this i have done following things,
replaced gearbox
cleaned fuel pump
replaced spark plugs
cleaned EGR valve and throttle body including TPS
checked cam and crank sensors
checked oxygen sensor
unfortunately none of above helped.
