What did you do to your Ranger today? (Part Deux!)

I haven't heard of too many warped intake manifolds so I'm pretty sure your luck should be ok there.

I forgot to note in my last post that there is now 3 Rangers in the parking lot at work, out of ~20 employees there's my '97, a '99 2.5 manual regular cab and the one I mentioned above.

I changed the thermostat in the Road Ranger after it wouldn’t warm up when it was cold up north.

When I opened it up, something on that truck I haven’t touched before, the thermostat was in backwards! I put in a 199° thermostat, facing the correct direction. 192 was spec.

Riddle me this: from the day I got that truck it has run extremely well, but it always had a little gurgle from the left bank of the 4.0. I won’t call it a miss, because even though that gurgle got soft and some times got loud and sloppy, and there’s always been soot in my left stack, it always has had steady power, and plenty of torque. I’ve changed virtually everything that controls the engine, except the injectors, and I’ve been assuming an injector was just letting too much fuel go in, which somebody explained would give it the gurgle and soot, but if the valves were opening and closing properly, you wouldn’t lose any torque, just a little bit of gas mileage.

Does that make sense? I guess I’ll see you after I drive it a while.
