Tickover RPM?

Feb 08, 2005 4 Replies

Hello all,



Thanks for all the useful advice today. I can see already that owning/running this Volvo of mine is going to be great fun.



Last question of the day (for real this time), my engine idles at just over 600 rpm. I'm sure I read somewhere that an automatic should idle at around 900 rpm. Is this true and what would be the best way to raise the idle rpm? This is a 1990 740 SE 2.0 Auto Estate btw.



I'm not convinced that the dial is correct but don't have access to the right kit at the moment to double check. I won't, obviously, adjust anything until I can verify exactly what the idle rpm is.



On a lighter note, I had some spare time this afternoon so I decided to 'get-to-know' the Volvo a bit more. I've had the car since Saturday and have 'played' with it everyday since and it still keeps throwing up surprises. Nice ones as well. One thing I did find was that one of the exhaust manifold bolts was loose. When I say loose I mean sticking out of the engine block by about 3/4 of an inch. The gasket wasn't blowing at all but I tightened it back up anyway (don't want it rattling out and going through the windscreen of the car behind me). As I was tightening the bolt felt very 'dry' as it was being tightened. Anyone else come across this before?



Much more fun to drive than my old Peugeot 405 1.9i GTX. I know how captains of ocean liners feel now. The Volvo is massive.

I don't think the idle can be adjusted - it is under computer control. My '85 is definitely from an earlier generation, but the idle is fixed at 750.

900 would be pretty high.

Pretty sure this is a UK spec car. We still had K-Jet fuel injection up till about '89. I suspect a '90 car would have L- or LH-Jet.

Thanks for that. Always worth checking these things. I guess the tickover must be okay as the car can still pull away without me pressing the gas pedel.

As the other ones has said, the idle speed can't be *adjusted*. But a few thing could *affect* the idle speed. I would start to check for vacc. leaks.
