Hi

I have a 1.2 T reg Bravo. It is quite high mileage, and seems to run nicely at high speeds.

However it has started having problems when idling, the revs drop and the engine labors. And also when driving, when slowing for traffic lights or something it keeps stalling. I took it to a garage with this problem a while ago and they reset the ECU. This solved the problem for a while, then it re-occured and the garage reset the ECU again, which solved the problem for a shorter time.

I have heard about stepper motor problems, could this be the answer. I'm a bit relunctant to spend £200 on getting a new one fitted if the problem is just going to re-occur.

Does anyone know what else it could be, and also if there is somewhere I could find detailed instructions on changing the stepper motor if I wanted to do it myself. ???

Also does disconnecting the battery for a couple of hours reset the ECU ??

Thanks

Matt

sounds like it could be the stepper motor,incidently you can reset the ECU yourself by disconneting the battery for 20+ minites and reconnecting.

haynes manual would cover fitting the stepper motor though there never usually a hard fit/

I have a T reg 1.2 Bravo on 100k and it's had these symptoms in the past. If your air filter's clean, your plugs and plug leads are ok then it will probably be your idle valve or "stepper motor" or idle pot or idle actuator which are all the same thing.

£200 seems a bit steep. Mine was under £100 in 2003.

I would change air filter, plugs and change plug leads if they are 50K or more then reset ECU. Disconnect battery for at least 6 hours if you can. Symptoms might be occasional stalling when coming to a stop or manoeuvring. Your oxygen sensor can do the same thing but you would notice high fuel consumption maybe only 270 miles to tank and possible hiccups on acceleration

If the idle plummets, engine chugs then blips up to 1000rpm, plummets again, hanging on for grim death, possible smoke, smell of fuel, difficult to restart perhaps then thats more like idle valve

Having said that, mine just stalled away for no reason whatever in the middle of gearchange yesterday. First time in months. Restarted and it's fine. Cars have to put up with a lot of changing conditions and sometimes the ECU gets it wrong

Hi check rubber pipes for air leaks.

On the coops, this can be removed and cleaned with WD40. Something to try before thinking of replacing the part.

a steppermotor is not the same as a idle control valve! the brava/bravo has an idle control valve on 1.6/1.8 engines.it can gunge up with oil etc and will need a good clean.steppermotors are usually fitted to single point injection.

now we are cooking.
