Idling Sucks W/surging&stumbling

[randbstar]

Hey everyone!
I need some assistance on this issue i keep encountering.

PROBLEM: Idle problems, such as surging or stumbling.

Basically in morning i start my car and it runs fine. If i turn it off for a while, like go into a store or something, more than 5 minutes it starts tripping HARD. I turn the car on, idling is not steady as though it wants to cut off. I rev engine and it is hesitating or bogging. I turn car off AGAIN and restart, let it run for a minute or so and the problem clears up and drives fine.

SECOND ISSUE: when it is driving "normal" after about 5 minutes or so i suddenly loose COMPLETE power. My RPM are dropping drastically. I press on gas pedal for more gas but nothing. When my foot is on the accelerator nothing happens but when i am releasing my foot off it, that's when the power is trying to kick in and starts surging. At this time i am just cruising down the street with no power. I pull off the road and come to a stop BUT before i can stop the car cuts off.

What the heck is up with this 50?????

I cant pass smog because no good reading. It kept aborting the test. So i couldn't even get a list of reasons why it wouldn't pass. I was told, "oh its your tranny, no its your rear end, oh no its definitely your cat converters that are bad."

SOOOOOO
i rebuilt the tranny, put an H-pipe with cats, upgraded rear end to 4:10 w/posi, replaced the throttle air valve, replaced the TPS, replaced the o2 sensors, replaced ignition wires to ford racing 9mm, replaced distributor cap and rotor, use fully synthetic oil, K&N air filter and K&N oil filter.

All these things i have done has helped improved my speed and sound BUT none of them resolved this jerking/bogging/stumbling/surging problem that i have been facing for the last year!!!!!!


SO i am willing to take any suggestions and try something else.

Do anybody know if adjusting the idling setting on he throttel body will help?

Any assistance is greatly appreicated!!!!
