Low engine idle after fitting extractors ??

[stirringaxe]

I have had a low engine idle since fitting extractors.

The engine idled at about 900rpm before, but now more like 600rpm & car now vibrates at the lights etc.

V6 Ecotec Auto Calais. Someone suggested pulling some ECU fuise for 1/2 an hour but I don't know what to try ?? Suggestions anyone

900rpm is too high. Is it auto or manual? Is this in neutral or drive?
For an auto the correct idle speed is 725 + or - 50 in neutral, 650 + or - 50 in drive, so if your 600 rpm is in drive, it is quite normal.
For a manual it is 775 + or - 50.

No it is too low. Can anyone advise how to lift it please.

No it is too low. Can anyone advise how to lift it please.

First of all, don't mention it. Second, I didn't make up these figures. You say it idles at 600, the manual says that is OK, so your vibration could be due to something else.

Can someone advise on how to lift the idle please

if you change the idol the gear changes are going to be all over the place and use more fuel
gear mounts and iac fixed mine
and maybe some other stuff?sensors,plugs,leads,coils etc it will keep your car running much better and more efficient

THIS IS AN AUTO..... not manual.

I want a lift in idle speed of not much more that 70-100 rpm when in Drive.

I have replaced the engine mounts, cleaned the IAC, tested the coils, replaced the plugs & leads.

BE CLEAR HERE. The car runs fine. Smooth, no misses or heavy fuel consumption, lots of power, good throttle response etc etc.

THE IDLE IS TOO LOW. A slight increase in idle speed will solve my vibration issue.

HOW DO I DO THIS? IS THERE ANYONE WHO HAS THE ANSWER ?

Open your bonnet and read the red sticker above where your radiator sits. This clearly tells you that you CANNOT change your idle RPM and also tells you that 600RPM is perfectly normal.

The only way you might be able to get it changed is to get someone to flash your ECU.

STOP being a dick to everybody in your thread. STOP being a rude ass and listen when people offer you advice. If you don't want help, don't post. If you do want help, read what people have to say because the CORRECT way to fix your issue is probably in one of their answers.

Oh now I'm a dick. I asked a simple question hoping I might get some intelligent responses. Guess not. I haven't bad mouthed anyone. SO HEY DON"T BAD MOUTH ME.

Oh and Mick if you haven't got anything positive to add DON"T POST EITHER. I can read perfectly well, I know exactly what the sticker says. Now can you read my original post ? This issue arose after fitting extractors, the idle speed has dropped significantly immediately afterwards. Was fine before.....now TOO LOW.
