P0172 code after aggressive & fast driving

So I got this truck from a Mexican brother who spoke no englas off Slauson Ave in LA with the Check Engine light removed and a replaced odometer that read 172k (carfax said 475k lol). She runs good. Definitely been hit on the drivers door and broken into the back window a couple times.

Now when I checked the codes I only got the one P0172 running too rich code. This code pops up from time to time and goes away after about a week.

I have noticed it tends to pop up when I drive 85-100mph and shift at higher RPM. I’ve also noticed when she’s warm she takes 2-3 key turns to turn over.

My guess is leaky injectors, maybe a sensor on top of that. The airflow is solid, spark is good, so it’s definitely a fuel problem and/or sensor/electrical issue.

I’m waiting to get some money together to buy the million dollar Toyota injectors, but while I get that together I thought I’d hop on here and ask around.

LMK, thanks ‍
