My engine started running extreemly rough and finally died on the I-15 & Field Rd. I had to call CHP for a tow and 59 miles and $594.00 later I made it home.
Here's the story on my Jeep.
Two friends sugested I check the TPS - a sensor on the fuel injector
So I called the mechanic that Mitch always used on this Jeep. He said that with this version of GMC Throttle body fuel injection, it's almost never a probelm.
This morning I finally was able to work on it. I knew the rotor & cap didn't look good, but before I went to the Autoparts store, I pulled a sparkplug. It was aweful! So I bought plugs, a cap & rotor.
I replaced the cap & rotor, started the engine, it did start but ran really crappy.
Next I replaced the spark plugs, started right up, ran way better than before but was idling very rough. While changing the plugs, I finally saw the elusive vacuum leak I thought I must have.
Kinda hard to describe, but on the rear of the valve cover is a ell fitting. It has what looks like a plug wire cover on a distributer. It was almost in two pieces where it reduces from a 1/2" ID to a 1/4" od tubing. The autoparts store didn't have anything like it. while at the store I figured out how to fab one using a 2" piece of 1/2" ID rubber hose and slip a 1" piece of 1/2" x 1/4" hose in it with a little rubber cement to help seal it. Put it on, works like a champ!
Jeep is now running better than it has in a long time. I'm hoping the plugs fouled because there was a vacuum leak and maybe allowing the enging to suck a little oil in.
In my morning prayers, I told the LORD that I don't ask for stuff like this, but If He would give me wisdom in how to solve this problem. He listened and gave me a helping hand!
I've been worried sick about the engine since Saturday thinking the worst like I need a new engine. I'm so thankful that it turned out to be realitively minor problem.
