So my car generally speaking seems to fun fine besides some stutter at idle, and we've had it once or twice die when decelerating quickly off of the highway. I recently replaced the coolant reservoir because it had a big crack in the bottom but it is still slowly leaking coolant from somewhere. I bought some Stop Leak coolant sealant that I just put in yesterday.... I ordered a new Vapor Canister Purge Valve Solenoid for one of the codes that likely will fix that issue, and is cheap and easy. The underboost I'm going to have a friend do a boost leak test to see if there's a leak somewhere otherwise I may have to look at replacing turbo, but what about the other codes I hardly found any info on the P0650 for some reason it seems like no one seems to get that code, haha? Car has around 180k miles.
Potential causes for
P0650 may include:
Burned out MIL bulb/LED
MIL wiring problem (short or open electrical condition)
Poor electrical connection at the bulb/cluster/PCM
Failed/faulty PCM

P0650 Malfunction Indicator Lamp (MIL) Control Circuit
Check the connection at the water outlet. It has a tendency to disintegrate and crack.
Potential causes of a
P0299 turbo underboost code include:
Intake (induction) air restriction or leak
Failed or damaged turbocharger (sticking, binding, etc.)
Faulty boost/charge pressure sensor

Potential causes for this code,
P0299, to set are:
Defective O2 sensor(s)
Burnt, broken, or disconnected wiring and/or connectors
Defective catalytic converter
Engine exhaust leaks
