vacuum

So I've gone quite a few places and can't seem to fix my explorer. Not looking for a miracle, but though I'd share it's history with you guys and see what happens! One day out of nowhere, my '93 XLT started revving from about 500-1500 over and over again on its own. Only time it would stop is...

I have a 1998 Explorer with a recently rebuilt motor 4.0 SOHC V6 (intake manifold was not replaced) 2 wheel drive that about 75% of the time sucks air so hard from the line (small 3/8" or 1/2" id hose) that goes from the air filter housing hose (large 3" id duct style hose that's preformed) to...

Hey guys I just joined the forum and wanted to ask about a few things: 1) While driving i can hear a squeaking noise coming from the underside of my car, sometimes i don't hear it at all but typically as i accelerate the noise's frequency goes up. I was wondering if maybe i just need to lube my...

Hello, so first off i have a 92 explorer xlt, when i bought the car the only thing that would worked was the main vents (for heat). To pass inspection here i need the defroster to work also, of which it wont switch to. Ive checked the vacuum lines that i know about and they all seem fine...

LAst week, exp was running rough,on the way home from work, I found that the plug on vacuum port at rear of plenum had fallen off, I re covered it, and it runs OK. NO Check Engine Light. But, when it starts, the idle runs high for about 20 seconds, then kicks down low and goes lower till...

The diagram was in Ford's software.

my 1991 explorer has been backfiring, so on the advice and the good people on here i did a compession test, the results are as follows c1=130 c2=130 c3=145 c4=150 c5=140 c6=140 20psi difference between high and low and i didnt see the needle lose pressure so i dont think i have a leak, is...

Hi guys, Im a newbie here, but so far seems great. I have a question I dont see an answer to. Maybe I'm just having trouble finding my way around here efficiently. Anyways here goes: I have a 96 Explorer 4x4 with really high mileage. Just bought it cheeep. It has the 4.0L v6. It...

My 1996 Ford Explorer engine decided to act like a prom queen asked to undress on a float -- it just stopped running well about 1500 miles when pulling a trailer slowed to about 20 mph, and without trailer about 35 mph on straightaway -- neither engine nor motor race, smell a lot of gas It is...

I have two broken lines and only one line that is hanging freely. there are six rubber elbow fittings sticking out of the part that sticks out of the intake manifold. I know the one that goes to the transmission and the one that goes to the brake booster. But I don't know what the other lines...

So I've searched the threads on here for days and decided to break down and start a new one to answer my problems. First I will list my symptoms with my '99 Ex Sport, OHV. ~150k miles 1. Terrible mileage, about 13 mpg 2. Starting takes a hair longer after she sits for a couple days than when I...

My timing chain broke and in an effort to see which or if my cam shafts are spinning I cranked the engine without valve covers. I had the fuel pump disabled as well as the spark plug lines, but something sparked and set that insulating foam b/w the upper intake and the motor on fire. Some things...

I'm hoping to get some input regarding the function of the vacuum line on the back of the FPR. I am having a problem with performance in that my truck will intermitantly bog down (happens more often when it is hot) and it will also backfire "cough" when I mash the accelerator at a stop...

I have a '94 explorer 4wd auto trans. It will shift into reverse or park with only a slight 4sec delay but OD, D, 2, and 1 give it a 90sec to never delay on the shift. Once in gear It shifts just smooth between 1, 2, 3, etc.... It has ATF and I changed the trans vacuum modulator. I think it...

I'm posting this as I believe that it might be helpful to others. :D I still haven't found my vacuum leak

have the v6 4.0L SOHC engine-new crate engine in fact-but am missing a vacuum hook-up-the diagram on the hood doesn't show all the lines-have four lines from cental pcv valve, two go to EGR module, one set back to the fule pump/canister but one just hanging currently-anyone know where I can find...

I've had my 96XLT since 02 and it is my daily drive. Last week the air stopped blowing inside and I looked under the hood and there were 3 vacuum control lines that were not connected. I assume something fell off but I can't find any pictures or diagrams to tell me how to connect the lines. One...

95, 4-cyl, 2.3L engine with factory air. Had this truck for about 8 years.The AC used to get so cold you could hang meat in the cab. This year the AC has lost a lot of it's cooling power. Freon has been checked and added a bit to place it just on the higher half of the normal zone. The big...

I had a replacement motor put in by a local mechanic but after picking it up I noticed that my wiper fluid warning was appearing. I checked and noticed that one of the lines was hooked up to the wiper fluid hose! I disconnected it and hooked up the wiper fluid hose where it was supposed to...

ok here's my issue, in the course of tuneing up and working on the engine, i've broken many vaccume lines, so many that i dont know where everything is anymore, i do know that they would go to the vacuum tree, anyways the only thing's i have hooked up to the tree are the break and cruise, and...

I have a 98 ranger 4x4 that would'nt go into 4wd, the light on the dash would come on and the motor on the transfer case was working properly but the hubs wont engage. Iknow that they are operated using a vacuum so i checked for leaks in hoses and checked to see if i was getting vacuum from the...
