Well, I tried to revive the thread below and nobody bit, so maybe a new one will grab a few bites ha. After searching and reading a bunch of threads I found this thread that describes my issue to a T.
Weird intermittent power loss
...but nobody ever posted a fix. I'm including the video from the above thread that captured it happening on film and is pretty much exactly what mine is doing.
230k '91 3FE
About three days ago I was driving down the highway on the way to work at about 70mph (~45*F outside) and it's like I sucked up a bird (airplane joke). Stumbling, losing power, returned to idle (where it idled fine) regardless of throttle position. Pulled over- thankfully there was a parking lot, left it running- idled fine, popped the hood, moved the throttle by hand and it would sort of get a rise in RPM, but not steady- kind of stumbling, hopped back in started driving after letting it idle for a few minutes, started driving fine the first 300 feet then started chugging and kind of surging regardless of throttle position...then VOILA! Came back to life normally, revving and all, and I drove the next 10-15 minutes at 60-70mph with no hiccups, surges, or issues whatsoever.
My initial thought was fuel, as I had filled up the night prior. I also checked oil the day before and added a quart (which is normal in the old girls life right now, sadly...I know the 3FE days are numbered).
Tonight, driving home from work, and it started doing the "bog/surging" deal again, CEL illuminated, but I popped it in neutral and revved it a few times and the issue went away immediately Then about 10 minutes later, I'm doing about 70 and it started again got a check engine light and the engine died. Like straight up died while doing 70mph in traffic, put on the hazards and pulled off to the side with it in neutral, as I'm coasting to a stop I try to start the engine again and it fires right up. Idled fine, revved fine, then put it in drive and drove the rest of the way home (10-15mins) without incident.
I'm about to make a 400mile drive to Atlanta and would really like to make it back home for the holiday (currently working in NC) without incident.
Anyone got any thoughts? I know TPS, fuel pump and filter, fuel sock etc were all mentioned in the above thread, but didn't seem to solve his issue...before I start shotgunning parts, figured I'd ask the collective mind. I'm sure none of those would hurt to be changed... but if someone chased a similar issue and fixed it I'd love to hear it.
