Kangarooing at low throttle

[kevin31157]

Hi everybody. JUst had the coil pack, plugs, fuel filter and injectors replaced which has finally stopped the car running like it was running on 3 plugs. Turned out to be one of the injectors gone down. NOw the car is back on the road and straight out of the garage i notice on a run that at idle and sometimes approaching traffic lights when the revs drop down at almost coming to a stop the revs drop to around 500rpm instead of the normal 800 and then comes up to 800 whilst stationary. Also at low throttle say in a traffic jam the car kangaroos until i get up to a decent speed and then it runs ok again. I have it in the garage to get them to have a look at it and they are at a loss and cant figure out what the problem could be. Any ideas please. FEd up with being off the road for so long.
regards
Kevin

Hi, maybe the idle air control (IAC) valve could be faulty?
Have you reset your ECU since you have made all the maintenance?

HI Giniw, no i haven`t and not sure if the garage did, I`m guessing probably not. I `ll have to ask them.

Just disconnect the battery and then reconnect it that will reset the ECU.

Maybe it could be a faulty mass air flow sensor (MAF) too if it's not just at low throttle? (if it's just at low throttle, I would say it's probably not that)

Check the timing its worth doing anyway 9 times out of 10 its out.
