Question about 1992 Ford Explorer

2 Answers

Transmission problem transmission leaks but not from transmission.. its leaking at the vaccum hose on top of the engine (i believe).. there is significant "fluid" around the hoses but i'm unable to distingush the fluid. my transmission fluid is gone in a month. HOWEVER i changed my oil and put the exact amout of quarts in as perscribed by ford and a month later my oil level is WAY above where it was. Is it possible that is where my transmission fluid is going due to a vaccum hose? another thing to consider is that not very often, but my truck has a tendency to crank but not start, then after about 3 sec of cranking i let off and it blows anywhere from 2 to 4 of the vaccum hoses off. I put them back on but (questioning myself) did i not put them back right? it runs great so i thought nothing of it but now wondering if these vaccum hoses could be my problem. i am not familiar with what these hoses go to so in very simpleton terms, any advice would be GREATLY appriciated. oh i'm also loosing ( but not leaking from anywhere on the brake sytem) brake fluid, another possible symptom? i dont know.. please help

The vacuum modulator that the vacuum hose connectes to at the transmission has a ruptured rubber diaphram, replace the vacuum modulator and the vacuum hose.

    the brake fluid loss is not related, I strongly suggest you have the brake system inspected ASAP for the source of the leak before you have a complete loss of brake pressure.

Check brake fluid leak on each wheel, external portion of the brake master. if no leak is visible, brake fluid is probably sucked in to your brake booster and to the vaccum hose towards the intake manifold and burned by your engine.

I get a whistling noise i think is coming from throttle body

Your whistling is quite possibly a vacuumn hose leak on the passenger's side, top of the engine. Look closely at the hose connections coming from the PCV. Small holes can develop in these vacuum line connections, and you will experience a rough idle, as well as the "whistling" noises.

Car dies when either put into gear or pressure is applied to gas pedal, what's wrong

i would 1st check all of the vaccum hoses to see if 1 or more is leaking, or has holes in them, you can do this by running your hand along the hoses, but don't get into the fan. "while the engine is running , if you find a hose that is leaking and you hold the hole closed , the engine will run normal. then replace what defective hose, or hoses you fine, i had a friend that had the same problem, and his was a vaccum leak, hope this solves your problem.

Need to know the Locatons for Vaccum hoses I have

Easiest way to find a vacume leak is to get some soapy water in a spray bottle and when engine is running look for any appearing bubbles that would signal a leak. All vacume hoses are simular in looks black rubber ranging in size from pencil to thunb in diameter. Vacume leaks are time consuming to repair and occasionally frustrating just be patient and listen with your ears.

1997 Chevy Cavalier is backfiring and sputtering sometimes on take off or acceleration. Any ideas what the problem is? New fuel regulator, all new injectors, done alot to this car.

Here is a list of some things that can cause it,
Emmissions system not functioning properly,
Faulty secondary ignition system
Fuel injection system in need of adjustment
Vaccum leak at fuel injectors, around intake manifold, or vaccum hoses
Clogged fuel filter
Weak fuel pump
To test for a vaccum leak, get a can of starting fluid, with the engine running, spray around the intake manifold, the vaccum hoses, connections and fittings, where ever you spray and the engine rev's up a little, you found a leak.

You can generally find a vaccum leak by pressure testing the system. Most auto parts stores sell a vaccum tester relatively cheap. Or you can take it to a shop and they will pump your sytem full of a uv sensitive die and then use a black light to find the leak. If it says vaccum leak at engine on the vent solenoid then all you need is the schematic of your vaccum system to find the solenoid and you should find your leak theoretically.

You have a vaccum leak on the mustang. Unsure of the Contour.. I believe it is the middle hose where the three fittings are (right in front of the driver seat in the engine compartment) Mustangs are notorious for vaccum leaks there
