30-40 yr old plastic! You can test the sensor itself with a blow dryer kind of like a coolant temp sensor. Also if your pcv is ran to the back of the intake, move it to the tree and put your booster on the back. I would wait until you add the catch can to do that.

Welp some good news, drove it this morning without letting it warm up and it ran great, didn’t hesitate or try to stall once and it slowed down good. Hopefully that was the problem lol, Thank you for pointing the intake temp sensor, all the other forums I read that had similar or slightly different symptoms was leading me elsewhere.

Glad you got it fixed, hopefully it stays that way! Report back after a few days to day either way! The air temp is less common, but one of the factors for warm up, which I initially missed also.
get that intake cleaned when you can. You can try seafoam through the intake for starters. You’ll be surprised on how much the catch can will get.
@rwfid for the catch!

It feels like it is random, even when it’s warm outside it will stutter sometimes but rarely when that is the case

PIP maybe? Did you ever get your reader and check for codes? Are all of your sensors and ignition components looking good now? Have you checked for vacuum leaks?

Got my reader, no codes, most of my sensors are new from the last owner. Ignition components are good, and no vacuum leaks

Sometimes it dies, sometimes it just stumbles and recovers

I forgot to mention that earlier, the computer even looks new. I looked at it when I was cleaning the interior last Friday
