How big a deal is it to pull the distributor and check out or change that gear?
it sucks, the cam sensor (i think) is und the cap and the crank sensor is on the front of the motor.
Have you noticed a loss of power from this? My guess would be one of the converters.

I don't think so...
the weird thing is that it's only when I let off the gas or am using like 1/4 throttle. It actually feels like too little backpressure...or like when I'm engine braking down a steep incline (in the yota)...like the computer's not sure how much fuel to put and when to fire
see what happens if you're coming upto a stop light and down shift to second then to first while braking (ie manually downshift) if it does it real bad then and sounds like a Porterite with glasspacks, then i'd say cat or maybe even muffler though I think yours is pretty new. If you're not really losing power then I'd doubt its one of those sensors.
I'll try that, but I suspect what you described will happen. I guess I need to crawl under it and look for leaks as well...I'll feel pretty stupid if there's a gaping hole in one of my cats.
and yeah the muffler's only about a year old Flowmaster. I wish it would blow out, it's too loud and I don't think it provides enough backpressure
It wouldnt' be a hole in the cat. The insides are ceramic. They can break and rattle around and clog flow.
