1200 rpm

[ikp_77]

checked over all the work that i have done on changin the pcv system found nothing but still got high tick over wot should be done to drop the rpm down chears out there

[AlanG]

Definitely no vac leaks mate? Mine was the same,and guess what? Yep......vacuum leak!!

[ikp_77]

yep no leaks should i check every thing again tho chears

[ikp_77]

were was your vac leak mate if ya do,nt mind me asking

[AlanG]

Can't go wrong with that mate. Is your car pre-ME7?

[ikp_77]

yes its a 98 mate think it is any way lol

Should be same as mine then buddy. They're famous for the vac elbow to the timing side of the inlet manifold perforating. If you do a search on here,you'll find a "how to" on replacing the little bugger for no cost. I posted this some weeks ago under "The usual suspect" First place I'd look. HTH.

[ikp_77]

i stripeed it all back down again there is no vac pipes loose as replaced them all a week ago put it back together and still high reves when i was messin round with the car i hit a large connecter block next to passenger front lite and it caused the engine to cut out could that havesumit to do with high reves and wot the hell is that block

[AlanG]

Not sure mate but my honest opinion is no. Sure someone will be along to identify the part in question. Have you cleaned the throttle tube? They are prone to sticking in old age and can prevent the engine from returning to the correct idle speed. Have you tried blipping the throttle to see if it drops lower afterwards?

[MARKY70RRR]

mine did this for ages and now and again it would thro a light up on dash found it to be idle control valve,cleaned it and even soaked it in cleaner for a day,but after a run it went back to idling high,in the end bought a second hand one off flee bay and it worked,hth

[ikp_77]

cheers i try that how much was the idle control valve mate

[AlanG]

Forgot about the ICV........1/2 hour job to give a thorough clean. I used WD40 as it was all I had but brake cleaner is better. Worth a try.

[ikp_77]

Do you think if i replace the icv it should cailm the revs down cheers

[AlanG]

If you are certain there are no vac leaks then that is what I'd be looking at mate. Have you cleaned it out yet?

[MARKY70RRR]

mine cost me a tenner there woz dearer ones but im a tight arse and wasnt sure if it woz that but it woz,best ten pounds i spent for a while anyway,good luck mate,

[ikp_77]

have not had time yet to clean it yet mate its parked up at my mams house as do,nt want to drive her incase i do any damage to it

[Diesel64]

If you've done the PCV, it could possibly be the inlet manifold hasn't seated itself properly when you've put it back. Did you use a new gasket?

If my knowledge is correct, it might also manifest itself as a slight misfire at idle if it is.

hope this helps...

Wouldn't worry about that buddy.........highly unlikely. I ran mine for a year,still learning about them and not driving like a lesbian,old age spinster either. Only put it right a few months ago.

[ikp_77]

yes mate new gasket fitted cleaned idle control today no change just orderd a idle control valve of e bay today hope this would the trick ,£200 from volvo for a idle control valve

[AlanG]

Very wise matey,would never pay the stealer that amount of money either. Hopefully that'll cure it then.......Forgot to say,does your car have the ECC? And does it work correctly as this can influence the idle speed too.
