Stock Throttle Body Issues
I've been having issues where my SRT8's idle falls off in gear. When approaching a stop sign/light, idle settles into 700 rpm for a few seconds, and then drops off to about 575. I can bump the shifter in Neutral or barely touch the accelerator, and it'll jump back to 700, and idle steadily until the next full stop.
I took it to the dealership today for unrelated service work, and they called to say that there were stored DTCs in the computer and that they were related to the ETC. I hadn't seen any MILs, and didn't find any when I last checked with my Dashhawk. Regardless, the stored codes were P2111, P0222, P0123. The tech also performed an "ETC follower test while observing TPS numbers" and found "ETC Assembly is sticking."
The Service Writer said they need to replace the ETC (throttle body), but it is on backorder and he hopes to have it in a couple of weeks. I have my SRT8 back for the time being, and I'm hoping that a new throttle body will correct the idle issue, but I have no idea if it's related.
Can anyone describe the "ETC follower test." And how likely is it that the "sticking ETC assembly" is affecting idle speed?
