Diag help needed
Need some diagnostic help from the Chrysler guys. 2016 Ram 1500 3.6 Pentastar. Customer came in with a broken intake resonator / intake tube that was taped together. Truck had a high idle and was throwing codes. Current codes: - P2173 – High Airflow / Vacuum Leak Detected (slow accumulation) - P0507 – Idle Speed Higher Than Expected Truck is idling around 1100–1200 RPM while the target idle is ~680 RPM. Here’s everything we’ve tested so far and why: • Replaced intake tube / resonator because the original one was cracked and taped up (possible unmetered air source).• Smoke tested intake system to check for vacuum leaks – none found.• Cleaned throttle body – minimal carbon but cleaned anyway.• Replaced throttle body with new unit after noticing throttle position PID acting strange (showing 0). No change.• Checked wiring and pins at throttle body – all good.• Checked MAP data – showing about 67 kPa at idle.• Fuel trims basically 0 (not indicating a typical vacuum leak).• Clamped brake booster line to eliminate booster leak – no change.• Checked PCV behavior via oil cap test – no major idle change.• Pulled EVAP purge hose and blocked intake port – strong vacuum but idle did not drop.• MAF sensor and intake tube are new. Scan data shows PCM trying to close the throttle (negative ETC duty) but RPM stays high. At this point it seems like the engine is getting extra air after the throttle body, but we haven’t found an external vacuum leak. Has anyone run into this exact issue on a Pentastar with these two codes and high idle around 1100 RPM? Wondering if this could be an internal intake manifold / PCV issue or runner control problem that won’t show up on a smoke test.
Processes
Quick question for the mobile guys who’ve been doing this longer than me. My process is basically: phone rings → I answer → I book it → I head out. It works, but it’s chaos. Everything feels fast as hell and I’m always reacting instead of actually running a system. I get about 5–7 calls a day and probably 30% turn into real jobs. My wife handles scheduling on the backend right now. Eventually I want her doing parts + estimates too, but for now it’s mostly me winging it. I’ve never worked in a shop or wrenched professionally. I came from dealing cars. I’m good at the work and customers are happy, but I feel too busy to even see where I should slow things down. For those of you who’ve built this right: - Where did you stop rushing? - What steps did you add that actually made life easier? - When did you separate diag, estimates, scheduling, and repairs? Not trying to overcomplicate it — just want to stop living in firefighting mode without killing momentum. Appreciate any insight 🤝

So I’m the mechanic, the sales guy, all of it lol when you spend 10k on a car to make 500 bucks the math doesn’t add up.
Ai
Is anyone using Ai for their company and in what ways?

I use it for diag. Pretty helpful tool.
Tekmetric??
Can i see a show of hands. How many of you have gone with Timetric based on my recommendations?

@Ben Dellaria damn really? We’ve been using them for a little bit and I don’t have really have a complaint. It ain’t perfect but I haven’t ran into anything of what you’re describing. the customer retention stuff is what really sold it for me. The two looked incredibly similar on paper when I demoed. I haven’t used tekmetrik, so I can’t compare both.
Thanks for accepting!
Hey all, I’m a car dealer located in Daytona beach. Little trick I’ve learned is that most the money in the car business comes from service, so I’m pointing my finger in that direction. Really cool community here.
