SOURCE: Oil Pressure Light Comes On after 10 min of Driving

You may not have put the right amount of oil in your car, your oil pressure sensor could be faulty, or you may have a leak.

By revving your engine, you're increasing the pressure and thus turning off the light and making the sensor think that it's at the correct pressure.

Check your tires, and lagers into wheels, that could maybe be problem.

SOURCE: 1991 Chevy Caprice has a mild miss fire and stall

Do you have the idle speed turned up to keep it from dying? Because it is high. Check engine light on? Have you checked for vacuum leaks at the gasket under the throttle body? How does the car run under acceleration? You might have a worn distributor shaft.

Testimonial: "Thank you for your tips and ideas you have gave me, One question, but before read my latest update. my car rpms hover around in between 1100 to 1500rpm at idle, but when I shift into drive it goes to a steady 1000rpm... is that good? if not, what are the correct specs. thanks again"

Rpm drop below idle


What's happening is, the engine is under increase load when the A/C is running. Typically there is a solenoid (near the throttle linkage) that controls idle speed when the A/C compressor (clutch) is engaged. It activates each time the compressor cycles on to regulate the system. If idle returns to normal when A/C clutch is disengaged (or A/C is off), then the solenoid or some signal that controls the solenoid to maintain the idle is the likely to be the problem. e.g. The solenoid fuse maybe blown. This might be a good place to start investigating the problem. Best of luck resolving this problem.

1998 Honda Accord engine rumbles and stops


rumbles?, did the RPM drop below 800 RPM? that is called idle failure
and when it does, idle can go to 400 rpm and will shake hard.
and is normal for illegal idle speeds. so post that first.
post that engine stalls
and that the RPM is 400-500 just before the stall.
then post if the fast right foot can save the stall (a key test !!!!)
if easy the ISC is sticking.
if tad hard the EGR is stuck open'
if impossible to save. then more possible (many)
ever do the 60k mile tune up this decade????,. if not why not./ now.

Where is the slave cylinder on a 2005 suzuki forenza


M/T car with a clutch
the slave is the device that pushes the clutch lever , as it enters the clutch bell housing (the hunk of alum. that is between the engine and trans 'bell shaped..)
400 or 4000? , my guess is you mean, 4000 rpm
3000 on the round is normal./
the engine should idle at 800 rpm.
that is just 1 tick below the 1 (1 = 1000 on the scale see the 1k or
x1000 on the dial, that means all numbers are times 1000.
so point 8 rpm is 0.8 x 1000 or 800.

do not ride the clutch pedal or you will buy many a clutch.
the save bad, never cause, slipping clutch. (near impossible)
the hyd, clutch actuator is self adjusting as clutch wears.
the clutch will grind gears if the slave fails. the slave annoucces its bad in advance buy loss of fluid on ground and level drop on the cutch master cylinder.
post the symptoms, and ask for help based on those facts.
a slipping clutch is a bad clutch. (or soaked in oil, and same )
please repost real RPMs using the x1000 scale factor for best answer
and when they happen.

My 2004 Mazda 3, normally idles around 1,000 rpm, the past few weeks it as been ideling around 500 rpm's, it shakes a little at this rpm. If it drops below that it stalls, only stalls when slowing to a...


Try unhooking one of the battery cables and leave it off for at least 20 minutes. When you hook it back up the computers should re-boot. That has solved problems for me with heater, interior lites, power windows, AC, day time running lites, power mirrors, fast idle, rough or slow shifting, CD player, and wipers on GM autos and S-10 PU and Dodge trucks. None of the switches are connected to the device they control anymore. The switch tells the computer to open the window and the computer send a signal to the window motor. When the computer gets confused strange things will happen or not happen. Of course you may have to re-set your radio stations.

The AC only blows cold only whenthe rpm's are at 900.


you dont,the aircon needs power to run so the computer is telling the engine to tick over at a no vibration speed,if it ticked over at the lower (400)revs,the whole car would shake.....
