This will be a long post, but I’m reaching out becuase I have no where else to turn. I’ve read pretty much every thread on the internet pertaining to the problem I’m having and nothing has worked. So here’s the problem... idles slightly rough. When I put it into drive it’ll drop idle to like 300-400 and voltage will drop and then it will catch itself and go to 500. Same story for reverse. In park it idles at probably 650. Also when driving, between rpm range of 2000-3000 it will almost hesitate and then begin to climb rpms again, like it’s fighting itself and it’s very consistent at doing this with or without the AC on. Speed still is climbing when this happens. WOT runs pretty great. I’ve checked every vacuum line at least 10 times. Spray carb cleaner around everything, no change. I have not pulled vacuum yet but plan to do that next week. Here are the parts I’ve replaced trying to figure out this problem... also the main problem is upon a heatsoak of 15-20 mins, when I start it, it’ll idle up down up down then die (approx 400-1500 rpm swing). Some times it won’t even idle up down, it’ll just start then die and then upon starting again, it’ll do the idle up down up down, have to give it throttle to make it stop. These are parts I’ve replaced.

TPS
MAF
PCM
Fuel filter
Fuel pump
Fuel pressure regulator
Battery
Checked/cleaned grounds
Air temp sensor
Coolant temp sensor
Coolant temp sender
All relays
PCV valve
Intake tube
Air filter

Ignition coil
Ignition control module
Harmonic balancer
Crankshaft position sensor
Purge selonoid
I’m sure I’m forgetting something. I’m at a complete loss. I’m about to replace the thermostat because I did come across something while reading that it could possibly be stuck in open loop mode. It does run pretty cool. Which would make sense. But I have big doubts. If that solves my issues though I will praise the lord. But I am posting to see if anyone else has ever had this issue and if they ever found a fix. I’m at my wits end, please help!!
