Conclusion

Seems cheap right? Well, there’s a problem. I started getting a rough idle and a misfire cylinder 2 code on cold start. That prompted the DIY remedy attempts of all new sensors, plugs (which I changed every year anyway), coil packs, fuel pump, injector cleaning, and two trips to the tuner for days at a time. His conclusion after driving around monitoring everything: probable burnt exhaust valve (not much else it could be). Once driving with code cleared, no perceivable issue at all, full boost, no stumbling, no backfires, nothing, it rips. Regardless, I stopped driving it immediately, bought a new car, and it’s been resting in the garage with a tender on it since (the last 4 months).

I speculate 2k for labor and head work more or less depending on how you’d do it. I would have done it too, except I got a new job right when this issue occurred, and I can literally bicycle there. If I were still laying down the highway commute you wouldn’t be reading this. But here we are. My circumstances are someone's good deal. But no regrets, it's been a lot of fun. Now someone else can take it all the way.
