I have a 17 with unknown mileage due to odometer fraud but over 200k new plugs new coils new egr stuff cooler pipe etc misfires at idle rpm or 1300 not burning any coolant in the last few months

Is there any other things to check or should I use this as a excuse to do a gen 4 engine swap?

Would fuel Injectors misfire randomly at idle and run fine when moving? Or do headgaskets fail other than burning coolant?

The pipe is sweating and dripping slowly as well but slower than the hose in the back of engine. What is it ? And is this normal?

*recently got a engine swap.

Anybody have experience with this issue? No check engine light, just the abs light and traction light turned on.

The sensor itself is working via a scan tool. Want to see if anyone has experience before throwing money at parts. Thanks!
