Title: Don't want to bother Daz on his hols but.......
Post by: Bionic on 01 April 2010, 08:21:01
Anyone tell me what the tickover revs should be on my petrol 2.5 auto Elite at normal temperature? Its running a bit lumpy at 500rpm. :-/
Apart from that small thing it runs as sweet as a nut now after Daz (the MAN :y) had done the heads etc. No more leaks of coolant or oil either, a clean driveway is a bonus.
 :D

500 rpm a/c off, 600-650 rpm a/c on

Cheers for that, I will have to look elsewhere then cos its 500 with the aircon off.

They certainly do,chris.Mine when warm ticks over nice and smooth at 650 with a/c on..if you switch it off revs drop to about 500 and seems to be quite uneven as if too low,so for that very reason I very rarely switch a/c off.

Ok, But my aircon is at the moment waiting for a compressor because the 'omega aircon specialist' pratt that diagnosed the leak as being the condenser, which I then had him change and recharge was useless because within days it had gone off again. This time I took it elsewhere and had it looked at only to be told that he had not fitted new seals which came with the condenser but that it was also the compressor front seal that was leaking. The dye the specialist (haha) had put into the system initially was bright yellow around the compressor but it was not evident anywhere near to the condenser! No, he had not washed it off after finishing the condenser change either! F'in robbin useless 'specialist' B*****D! >:(
So now I ask, as it will not be a job that will be done quickly due to financial constraints to get it fitted for me and being disabled I cannot do it myself (I already have a replacement compressor) would it be ok to raise the tickover temporarily until I get it fitted?
If I carry on running the aircon until then what damage will it do seeing as the compressor is already kaput? Should I just put one of those aerosol thingys from haflords in every once in a while to keep it lubricated until I get it done? Should I change the aux belt for a shorter non-aircon one if that is possible?
One piggin thing after another but at least I now know who I can trust.
Forgot to say... I usually run with the aircon on all of the time, it never gets switched off.

Yo're not running the A/C if there's no gas in the system, the low pressure cut out has triggered. The pulley on the compressor might be turning via the'fan belt' but the compressor itself isn't turning because the clutch iside isn't engaged because there's no gas in there  :y

Thanx andyB but can I temporarily raise the tickover little to stop the lumpiness until I get the compressor changed?

I think Tech II can ..... but not much you can do yourself  ;)

I know the EGR can be adjusted to increase idle, not sure if it can do the idle control valve itself  :-/

Yeah, remember taking it down to point of stalling, then up to about 1.5k rpm

Horlicks, young man, horlicks. ;D


Tech2 can increase desired idle rpm (which it obviously does electronically via ICV).  However, the aircon off desired idle of approx 450rpm should be pretty smooth. If it isn't thats the fault you need to look for.

I remember 'idle' being adjusted on my 2.2 via the EGR  :-/

I didn't think the EGR could alter the tick over.

Nope.

You may have remembered me testing your egr, which would have affected idle, but certainly not an adjustment method...

I would clean the AICV and check the MAF with a known good one if you have someone close by...tickover is not normally lumpy unless you have blockage or maybe a slight airleak etc...mines smooth at 500rpm

Bionic, if you want a really perfect idle (like I did) prepare to drain the budget.. starting with a new maf,
new icv,new valves, new gaskets under the plenum, new dis and cables, sound injector cleaning and so on..believe me not worth..
even a small hole in the exhaust or any leak from anywhere else will mess up everything ;D so dont bother.. :y
 
ps: I also find that NGK 4 electrode sparks are better for my cars idle..

Air con compressor on Estate bearings seized (to be replaced in warmer weather) so running no aircon and 2 lit aux belt (shorter) - tickover 500 rpm and dead smooth.

ticked over nice on Monday. . Wonder if it could be that lead that looked worse for wear?

Any codes stored? I'm not all that far away from you if you're stuck.

Hiya wellung666,
sent you a PM but with failing bionic legs like mine I am seriously stuck to a set of wheels. Possibly another transplant using wheels would be better than the metal bits I currently have stuck in me?
I could then excuse my ass as the exhaust...... Hmm, thats worth a thought or two  ;D ;D ;D
