Default Major stumble...can't figure it out.

When i am de-accelerating in gear and then i put the throttle more than 25% down it will blip the throttle and then pretty much shut the motor down for about 1-1.5 seconds, when this happens my a/f ratio pegs the FJO at 20.0, after about 1-1.5 seconds it will "turn back on" and drive normal. This is extremely irritating every time i shift, does anyone have any ideas or had this problem and solved it.

Only things i can think of that could cause the problem are...fmu, fields fuel controller, rc 310's, resistor box. I have a brand new fuel filter, fuel pump and i am on my 2nd tps sensor. I have not pulled the iac and tried to clean it yet. I am thinking something in the computer maybe or the distributor. This problem came out of nowhere, didn't notice it after any changes to my setup, haven't really done anything to my car except put new ground wires on it, 4 gauge off the head and tranny. I can't remember if it happened after or before, i think it was before. Anyhow...you help is appreciated, thanks.

is there a way to remove the fields vafc to see if that is the problem, if you turn it off would that solve it or when they go bad do they still mess things up when they are off, i dont know how it could shut off completely if the is wired into the computer harness.
