Truck Is Bucking

[dalejrfan88]

To start off i have a 97 GMC sierra 1500 2wd with the 305. About 3 months ago i did an s10 torque converter swap and then drove it about 700 miles. On my way home my truck jerked once just going down the road. Then i did it more and more and it got to the point where it would run it would just buck so i pulled over and it stalled out. So i start it back up and it is idleing really rough. So i try to drive it the rest of the way home and its still bucking alot on the way home. So i stop and park it for about an hour and start it back up and it runs alot better than it did before and it only bucked about 3 or 4 times over like a 30 miles. Now it idles rough and it will jerk once in a while when im cruising down the road or when i let off the gas. But every so often it will run perfect...great idle and no bucking the entire time its running. But i can pull off to the side of the road, shut it off and restart it within 5 seconds and it will run like crap again.

 

What i know: I have 3 codes, but for the longest time i only had code PO340. Now i also have code PO102 and PO441.

 

What ive done: Replaced the cam position sensor, throttle position sensor, PCM, plugs, wires, cap, rotor, distributor and the fuel filter.

 

What is causing my problem? I have had numerous people look at it and none of them can tell me what is going on here. I know im not the only person that has this problem but nobody i know that has it has figured it out. Please HELP!

Here's a forum about your P0441 code: http://www.automotiveforums.com/vbulletin/...d.php?p=3969344

 

Looks like you addressed the other issues. This site is good for OBD II codes: http://www.obd-codes.com/trouble_codes/

 

Sorry I can't be of more help.
