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.
