I don't know how many it "should" be turning, but my 2001 Turbo Beetle turns about 3,100-3,200 rpm at 70 mph, assuming of course that it is in fifth gear. I have a 2.0 liter, 2001 VW Beetle and I thought I saw yesterday mine ran at about 3500-4000 rpm
No, that is not normal. Should be around 2500 rpms.
You should be around 2200 - 2500 rpms.
Out 2000 Dodge Neon does 2500 rpms at 60 mph. Grace
Oil pressure ( minimum amount ) is 6 LBS. at 1000 RPMs. 18 LBS. at 2000 RPMs. 24 LBS. at 4000 RPMs. more pressure is fine too.
i have audi tt and low rpms the air gets cold but at 2000 rpms it get warm
Oil pressure ( Minimum ) 1000 RPMs 6 LBS 2000 RPMs 18 LBS 4000 RPMs 24 LBS It must have at least that much oil pressure at these different RPMs to LUBE the engine. If it has 80 LBS are more then the oil pump check valve is not working correctly
mass air flow sensor
depends on RPMs
Check for a vacuum leak or a problem with the EGR valve.
The engine coolant level is low. Add more and the pump will be able to move coolant at the lower rpms.
45 LBS. at 2000 RPMs. At an idle it should have at least 15 LBS. or more.
No less then 6 PSI. At 1000 RPMs. 18 PSI. are more at 2000 RPMs. 24 PSI. are more at 4000 RPMs. And that is factory specs.
