Rev Problem

28th April 2005, 23:27

My mate has just given my car back but when the car is not moving the car revs go up and down instead of just staying in one place, I have piper cams 285 and a dastek chip installed, it was working before it went in so what could this be

heard of saxo doing that alot but no1 seems to no why.now and then if i slow down like at a junction the revs will go high then back down.try avin a word where you had ure dastek chip fitted

you got a stainless exhaust? straight through? had the same problem on mine, its was caused by the exhaust not producing the right back pressure for the engine!

mine does it occasionally, i think it maybe the cams mate as they do affect the idle. maybe that it needs a re-map or has it jus been done?

might sound strange but when i had that problem it was because i didnt upraight my standard battery. If you have a sound system i.e subs amps ect.. they put a strain on the battery which when you are out and about with stereo on the battery isnt recharging well. so when you go to start it in the morning you may have problems with idling.. i upraighted my battery and problems haev dissapered

saxo's hay lol..

mine did that. Replaced my coolant temp sensor and that sorted it.
Also what Dico_VTS and Starkie have said may be pretty feasible (sp) options.

mine does it all the time, cuts out a lot too at the moment. think its coz my car is shit!

I do have a straight through stainless exhaust but if was working before it went into hospital

It has also had a new battery fitted about 2 months ago

So im not sure how this has come about but she is not well at the moment

I think ill go and get a computer read out and se what it comes up with

yeah mine is really bad at the mo, also jolts when u are driving at a constant speed when your foot is on the accelerator pedal, sometimes so bad the car is bunny hopping down the road! ive spent hundreds and its the same if not worse!

Ive sorted my problem all I did was disconnect my battery over night

When you start the car you will need to rev the car a bit more then normal for the first few miles but then it should sort its self out

hmm. Sounds like you may have had slightly blocked injectors. And with the ECU resetting itself, its set itself up to work in accordance.
