Weird Issues...

Also posted this at TF..

Having a head scratcher here....
This morning went out and fired up the tbird and it almost didn't want to idle at first,(kinda like a cold carbed car) but I blipped the throttle and that cleared it up. Then upon leaving it has developed a weird issue. At about 20% throttle it bucks, hesitates, and starts pinging. At 50-60% throttle it goes away. It actually seems better if I am hard on it instead of just rolling gradually on the gas. It also is not consistent, sometimes it happens every throttle sweep, sometimes not.

A little back ground -
Day before yesterday I changed out plugs, wires, cap, and rotor. Wires - Magnecore, Plugs - Denso Iridiums, Premium brass cap & rotor. I then drove 400+ miles yesterday from western NC to VA with no issues!? I did blow the ic hose off a coupla times but popped it back on and back on the road, no problems.

The car is always well maintained, has had NO driveability issues, and been in excellent tune as of late....hell it even got 29mpg on the trip down. Only mods done so far are cone filter on VAM, KS & BCS dissconnected (14psi boost).

I did run codes and got KOEO 22 42 65 & 81
KOER 25 & 76.

Help

Since you have a 42 and a 65 together as CN, look at these posts.

Code 81 is the disconnected BCS
22 is the BP out of signal range. Make sure there is NO vacuum hose connected to it and plug and unplug the connector. Erase the CM codes and see if it comes back.

Thanks Pete.
