sorry to hear of your misfortune :(
sounds like either a plugged fuel filter or plugged catalytic converter.
does running it with the air cleaner removed help at all?
I changed the fuel filter and I cut off the cat in order to get the right pipe size to reinstall it. I basically have no exhaust at the moment.
well its official you've stumped the auto psychic lol
relistling your question now so one our smarter experts can help.
good luck, gary
I've had a cat go out before on a bonneville with similar symptoms. But when the cat went out on the Bonneville I couldn't get over 15 mph. I can get the Isuzu occasionally up to 60 but only by barely holding down the accelerator and lightly tapping it. If I push down on it and give it the gas it will only bog down.

I'm trying to get it road worthy and put a new exhaust system on it. I should also mention that on Monday it completely died. Couldn't start it Monday or Tuesday which is the day I took out the computer. I put the computer back in tonight when I got home from work and I had nothing. No lights (computer lights check engine, seat belt, door chime no gauges, nothing. I gave up and threw in the towel since I put the computer back in EXACTLY the way I took it out. Was extremely gentle with it. But then a friend called tonight and asked how the truck was going. and I told him it was dead. But I went back out and tried one more time to turn it over and the computer fired up and the truck started. Came back to life like the terminator, although the no air problem hasn't changed. And code 61 still comes up when I run the codes. I
