Question about 2005 Ford Mustang

1 Answer

At idle 2005 4 litre mustang shows 50 psi at 75 degrees, when at normal temp pressure drops to 15,20 at idle. At 2,000 rpm shows 40 psi. This sounds low to me, is this normal?

That sounds normal. There would be specifications for it that you should check, but that sounds pretty normal. The specs probably show a pressure for idle at normal operating temperature, and another figure at a specified engine rpm. Or it may just have one spec at a certain rpm.

Does anybody know what the oil pressure specs for the 2006 crown victoria lx 4.6L at idle and at normal operating temp? Mine is reading between 15 and 25 psi. Has 149,0000 on it.


15 seems low. Ford gives a spec of 40-70 psi with the engine speed @ 2500 rpm engine hot. Most cars I see are around the 25 psi @ idle. If your idle is lower than it should be it will make your pressure lower. This should be a direct reading on a good mechnical engine oil pressure gauge.

I own a 1993 chev siverado.Im kinda confused as to why my truck will stall and loose all power to my ignition.


One guy I know traced it to his in-tank fuel pump. The computer reads that all of the electronic components of the pump are running at optimal, but a pressure gauge connected to the fuel rail on the intake showed the pressure was 58 psi at an idle and it dropped to 45@ 2000 rpm's. 58 psi is minimal for a big block, 60 is optimal. The book shows the small block should be around 50 to 55 psi for optimal pressure. The drop in fuel pressure causes the engine to lean out under a load such as accelerating and pulling and could cause the engine to burn a piston from the increased cylinder temp. I am not certain how this would cause ignition power loss though, unless that fuel pump has a safety cut out for electrical shorts, real or perceived by the computer.... Have to talk to some friends about that.

Check wiring harness around and including plug to the coil pack. Also check fuel pressure with vehicle running. I'm not sure of the specs but, Iit should be around 35 to 40 psi. at idle, and 50 to 75 at higher RPM's. I've seen Fords run with a bad fuel pump and demonstrate these exact symptoms

I just purchased a 2000 GMC Savana 3500 with the 5.7 litter engine with 92000 miles on it. The temp gauge shows that the engine is running between 100 - 160 degrees, seems too cold. The oil pressure gauge...


you probably have your finger on the problem. have oil pressure test .when engine hot minimum 12psi.and change the thermostat.Don't cost much

On my 1996 ss impala what low side pressure should I see on the a/c with the system running


It all depends on the outside (ambient) air temperature. Your A/C low pressure switch is designed to turn the compressor off at 24 Psi. and turn it back on at 45 Psi. Most systems will normally run at between 25 and 40 Psi when the system is running on HIGH blower and "MAX" or "RECIRCULATE". A system that is fully charged may run at 25 Psi when the ambient temperature is 75 Deg. (F) and may run at 40 Psi when the ambient temperature is at 90 Deg. (F). (it can be even higher if ambient temperatures are higher than 90 Degrees.)

To properly diagnose a malfunctioning A/C system, the HIGH side pressure must also be checked. Restrictions in the system can make the low side pressure look normal while the high side pressure is high enough to blow hoses apart. (400+ Psi.)

Oil pressure is normal until it reaches200 degrees then oil presure drops to 10 pounds at an idle but give it gas and it goes up when its first started oil pressure is at 40 pounds until it reaches 200...


Oil pressure drop after reaching operating temp is normally caused by worn main bearings (depending on mileage).Worn bearings will allow pressure drop at idle and increase when accelerated above idle.

What should a 2002 Pontiac Bonneville oil pressure gage read at


at what? depending on engine temp and rpm, normal oil psi should read 30-40 psi at idle and at cruising speed of 1500 to 2000 rpm should read 60-70 psi. most bonnevilles from 1992 to the last year run of 2005 have the 3.8 liter V6 which was updated over the years.

Air conditioner in 1999 mercury tracer won't work. It's not the compressor nor does it have a leak. what could be the problem?


the tracer is the same as the ESCORT, right?? TRY THIS--I WORK ON PLENTY OF ESCORTS--LOOK UNDER THE AIR CLEANER/CONE ASSEMBLY--THERE WILL BE A BLACK METAL BOX(FULL OF RELAYS) ONE OF WHICH IS THE A/C RELAY--TRY TAPPING ON IT WITH A LONG SCREWDRIVER OR SOMETHING SIMILAR WHILE U HAVE THE A/C ON. IF THE A/C SUDDENLY STARTS WORKING U NEED TO GET A NEW RELAY BOX(I THINK ITS CALLED A GEM MODULE) i do have a question- does the blower motor work?? how do u know the compressor is good??do you have 12 volts going to it??? this relay box is pretty common to go bad--u have to remove the air cleaner in order to get to it.get back to me.

OIL PRESSURE GUAGE, IT SHOULD BE STABLE?


bout the oil pressure gauge its normal to go up but not to high coz u might overheat, try checking the cylinderhead gasket if there is pressure coming out, replace the gasket if needed

Oil pressure


30 PSI hot idle is ok, 40-50 PSI at freeway speeds hot is good. this is based on using the correct weight of oil which is 10W-30W
