Need help! Bought a 55plate 1.4 sport a couple of weeks ago. Idle was very wavy and revs dropped off on acceleration almost stalling. Kept running it daily. Up to date, took air filter off to have a look at it as supposed to be K&n filter. Had a clean arounnd throttle.Put filter back on start up. Warning stop and fault of engine coolant temperature to high, temp guage shot up to maximum. Had a search around forums and couldn't find anything other than re-boot bci. Did this and second attempt it cleared (assumed it was due to messing with 'things'. started up today all warnings back including pollution warning. cleared again with re-boot. Started up again and could smell fuel faintly. All ok for about 2 miles then alll warnings bck on with what we believe to be engine light on . Idle really erratic idle and light steam coming from exhaust. Have no idea what to do next so any help would be wonderful.

Still not sure what pp2000 means but an update now. Few days later started it up and very brief pollution warning which went off. Engine light still on. Drove for a while and engine light went off. Idle andpull-away seem to have improved a little. Now a week or so on the idle is ok but pulling away in 1st , revs drop then shoot high so it sound like he's got a heavy foot. Sometimes the drop is so bad it almost stops, no fun at the traffic lights! Not sure what throttle we've got either as some googling produced a few types, some electronic and some with a cable so it 's hard to find out how to treat it . How can I find out what sort it is without taking it off completely and prob causing more damage!

Post the last eight digits of the VIN, and we can look up what accelerator system you have.

PP2000 is very well documented on this site - numerous posts and plenty in stickies, and any number of demo's on YouTube, so you can't expect a dissertation in response to your request. There is a short intro here, and a "map" of willing users here.

Hi again. Last digits are 44874590. Got in touch with previous owner who was totally oblivious to any issues, said it just needs a blip before pulling away as all small cars do... Not wanting to disbelieve as we havent had a small car for 10 years but prior to that we never had to blip anything but then we never had cars with computers in them either ?

The Service Box states your car has a motorised throttle, but it is not sure which type of accelerator pedal. The cabled type has a sort of thick bent-wire arm to the pedal, whereas the non-cable type has a straight arm casting.

You shouldn't need to "blip" the car. In an ideal world, you'd start the engine and it would idle smoothly. If it is rough and wavy, then there's a bit of a problem. "Blipping" shouldn't be needed.

Cars idle at about 800rpm, and most maintenance data says this has a +/- deviation, so some slight "roughness" can be expected.

A BSI reset is unlikely to cure mechanical problems like rough idle.

Have you managed to sort out PP2000 diagnostics yet?
