Can anyone direct me to where to find the Ported Vacuum Switch on my 1996 Ford Ranger 4.0L, 6 Cyl. 4WD. A picture would be GREAT. Still have a vacuum leak and still throwing parts at it. Thanks in advance.

Ok, Ok, thanks for that info. What's your recommendation where I should look?

So are you saying the crank position sensor maybe be bad? I guess I'm confused since I'm not any kind of mechanic. Thanks again for all your help.

Replaced IAC Valve, Throttle Body Sensor, Spark Plug Wires and Air Filter. All new parts. Sprayed MAF Sensor with MAF Cleaner. Still idles rough. RPM's goes down to abt 500. I think the MAF Sensor is next.

D I did it a couple of times, the spring never moved, the IAC just made a little "pop-type noise" like it was trying to do something. It appeared to be stuck trying to move.

Thanks for the reply. All the AC Tech used was a green pen light and looked all under the hood. I see those sniffers online at Amazon starting at 20.00 and up. Maybe worth the investment.

I went out and started the Ranger, when I unplugged the IAC Valve, the engine died. When I took off the IAC valve and just turned the key to 'ON', the IAC valve did not move and just made a puff noise. I guess the IAC is bad. Your advice and recommendation please.

So are ya saying, it maybe the PCM/ECM which is located on the passenger side, back firewall? I will try the IAC tomorrow morning. Thanks for the information.

1996 Ford Ranger 4WD, 6CYL, 4.0. I had the AC serviced last year (added freon) and all worked well for abt 2 weeks (COLD AIR). Over time, it depleted. I ran a dye and light all over the engine compartment but could not find a leak. Any suggestions on where to look before I invest again. Thanks.

Thanks for the tip, I will check with them. I just test drove the Ranger. The RPM's still drop but not like before. I think when I came to full stop, the RPM's went down to 4 or 500. I think tomorrow I'll get the new wires, ECT Sensor, IAC Valve and MAF Sensor. Will follow-up. Thanks again.

I cleaned the IAC Valve and the Mass Air Flow Sensor, that seems to help the idle issue. It idles at about 900 RPM's now. Thank you. I will replace the ECT Sensor tomorrow and the spark plug wires, since #6 gives a shock when touched (the others do not). Thank you again for your help.

Thank you for your assistance. Looks like a trip to the partshouse tomorrow with a wad of cash and get these parts. Will follow-up tomorrow with my progress.

P0117, P1443, & P0174 Here's some screen shots of my RPM's. That's as many as I can upload at this time I hope this helps.

Engine idles very rough and have to keep foot on accelerator to keep running. I know I have 1 bad spark plug wire and have replace the plugs. I do have 2 OBDII error codes, one has to do with the engine temp gauge (I put in a analog one) and an emission error (purge valve solenoid). Any...
