My 2017 Limited for some time had been randomly dropping RPMs at idle. It'd be like when sitting at a light or coasting to a stop. The motor would drop to around 400rpm, then catch itself back up. This went on for some time till finally it didn't catch itself and the motor cut off mid-driving. Fun times.
Took to my local shop, scanned errors indicated bad fuel pump. They dropped the tank and replaced and put back together and the issue happened when they test drove. New error indicated throttle body bad. That was replaced as well and truck was picked up. I've been driving for a week now and it's not shutting down but I still get the rpm drop to 400 at stop. So far it's recovered, but I'm worried that something still not right.
Any thoughts or similar experiences? AI dive says Vacuum lines test or idle control valve. I guess I'll be taking it back, but it doesn't happen on command.
