Pcm p0121 irc b0429 ipm b2463 irc u1016 help
Hi everyone, my name is nwodeville76, I own a 2004 deville dts w/nav, raven black, with neutral shale interior, I love my batmobile, it also has flashers on the front and back, my problem is a rough idle, and stalls, plus lack of going power. Usual codes are pcm p0121, I replaced the tps, but its an after market one, still same code, I tested the plenum, its good, battery is good,12.8 v after 45 minutes of non use, the iac was filthy so was the throttle body, I cleaned both, but the rpms are still a bit erratic, other codes are for no map disk, and a code for baffle door in rear hvac circuit #3 not in correct spot,and I get an occasional irc u1016 loss of comm with pcm, Sometimes get random codes in history,any input would be appreciated: )
