Hey guys a little over a week ago I had my sc rebuilt & a Glowshift boost/vacuum gauge installed at the same time. My car ran perfect prior to this rebuild & gauge install. After the rebuild & gauge install were complete we fired it up & I had a breif high idle. My tech took it for a test drive & the sec he got out on the rd & shifted to 2nd gear it went into reduced engine power the CEL came on & it had a total of 4 codes thrown. My tech cleared the codes & CEL & sent me on my way. A couple of days later the CEL came back on I started to get the high idle issue where I would take my foot off the gas & it wouldn't idle down & then it went back into limp home mode. I took it back to my tech & had him clean my throttle body out thinking something might have gotten in there during the rebuild. After he cleaned my TB he cleared the codes & we took it for a spin. The car ran great, we pulled over to the side of the rd & let it idle for a few min. After about 5min of idling it started to idle up high around 2k rpm for no reason & then the CEL came back on. It was the same 4 codes from b 4. He wants again cleared them & sent me on my way. My car has been running fine for the past couple of days & then my CEL even went off however shortly after going off I started getting the high idle issue after letting it idle for a few minutes & now the CEL is back on. I still have my original OEM throttle body & my car is a 2005 with 177k miles on it. Could it be that I'm do for a new TB ? We of course checked all of the lines & to be safe we are going to replace all of my vacuum lines next week. The error codes that I have are listed below any help you guys could give would be great I just purchased my ZZP 3" shorty header & down pipe & the 3" cat was next but if I can't get this fixed I'm dead in the water thanks guys.

The codes that I'm getting are


P0069-SC inlet pressure
P0121-Throttle positions sensor malfunction
P1101-intake airflow system performance
P0068-TB airflow performance

TB has to relearn idle and other stuff. He flapped the throttle body.

So your saying once the TB relearns then the cel codes & idling issues should go away ? How long does this process generally take ? I've been driving for about a week now since he cleaned my TB & the issue still exist
