Ok I have cried on here about needing/wanting a new truck for over a year. No I don't care about riding around in a newer nicer looking ride. I care about a work truck that does what I need and can be depended on every time I get in it. My truck pulls our campers, the vending trailers and enables me to get the lumber and tools to these 2 houses to remodel. For a year it has run rough most of the time and smooth as silk the rest. To hear it some days it sounded like it had a couple of cylinders missing. Gas mileage was 10 to 12 mpg. empty or hauling a trailer. Every thing said it was in the plugs wires or rotor cap all have been replaced over the year no improvement.
A few weeks ago a neighbor stopped by while I was selling BBQ just to B.S. and he asked "what is wrong with your truck it has been sounding rough passing by." So I told him what I had done and it hadn't helped. He told me it was "that little black sensor on the side of the carburetor" ok thanks. Now this is a "good ol' boy" he drinks way to much and has run through more trucks than shirts so I didn't think to much on his advise. Well last week I towed a friends truck to my old mechanic and asked would a bad sensor on the throttle body make it sound like a miss?
Butch said start it up. I did and he listened a second, naturally it sounded perfect. He walked to the back and smelled the exhaust. He said it was real rich smelling mite be the throttle position sensor or the Map sensor not the wires and plugs. Butch said he was full up with work all I had to do was loosen 2 screw and pop on the sensor and start with the "little black one on the carburetor side".
Well I got that 40$ sensor it took 5 minutes to swap them out and my truck started purring like a fat cat in your lap. I have spent 100s in gas because of a nothing part. Live and learn . A simple fix had me ready to spend thousands on a new truck.
