WTF is wrong: P0106 and P0505 codes and rough idle

jicl55 · 06-12-2009, 10:16 PM

P0106: P0106 - MAP/Barometric Pressure Circuit Range/Performance Problem
P0505: P0505-Idle control system malfunction

Car stumbles at stop lights usually after driving about 15 minutes or so, but sometimes immediately, seems to get worse as I drive tho.... there is wondering rpm at idle (hesitation, usually goes up in rpm from 550 to about 700 and then back down, but not all of the time.... again, seems to show it's ugly head after driving 4 about 15 minutes or so) and slightly rough shifts.... Vacuum leak or bad throttle body or something else to check? Had throttle body knife edged, could that be the problem that is throwing codes?.... whatever it is, I don't like it. Do have auto enginuity scan tool but am not extremely mechanical, so if there is something else I could check to determine WTF is up, please let me know.... thnx in advance.

with the P0507 code i have my idle doesnt bounce. but the car bucks and when i pull over it stops responding to the pedal. my pedal was replaced with a new one about a month ago so that's out. car has been at the dealer and they could not get it to do it, but i got a call this morning saying the tech that took it home saw it happening (finally). service manager(who is also working on the car himself) called me this morning asking if I had a larger TB on them car. I said yes and he asked me for the part number of the one I used because they are going to replace it.

I was a bit suprised that they are going to continue working on it. I will let you know when I hear something.

Try to take care of your 106 code as it may be causing the other one. If your MAP is acting up that will def cause driveability issues.

For me the P0106 was caused by the Y-Pipe that attaches to the TB was not on properly due to the flimsy plastic tabs that broke off that secure it to the TB. I made a custom bracket and now it's on TIGHT. Cleared the code and hasn't came back on since (been 300 miles)

As for the P0507 code, for me it was the TB wiring. The TB extension harness that connects from the TB to the harness (about 2ft long) was defective some how and the pin connectors were bad. That was dealt with and after the TB needed re-adaptation. Cleared the code and didn't come back. Hope it doesn't.

All is good now. Hope this helps.

P0106 came back with the same rough idle

Replaced MAP, problems still persists.

Good news everyone! I've figured out a way to use two different watch / unwatched overlays so now I can add them to the text-based lists. Update soon!
