What would make a 3fe run very well and after maybe 30min start to act like it’s running out of gas, stalling, unresponsive throttle but if you take your foot off the gas will idle perfectly fine, and after a minute or two go back to normal and after 20-30min start acting up again?
Hey, Have you hooked up a vacuum guage to the vehicle? I would and look to see if you have a vacuum leak when you get that stumble. If that theory tests out look at all your rubber hoses to see if you have any cracks. If not related to vacuum it could be that the wire loom near the exhaust manifold is getting warm and causing resistance which is throwing sensor signals off and causing the stumble. Check the vacuum first before jumping into wiring.
Thanks for the vid very informative
