3vze power loss after warming up
I have a 91 runner with the 3vze. It starts up fine and runs ok for about 10 miles and then it losses power and has intermittent misfire/stumbling. I changed the TPS thinking that might be it. didn't change. Today I disconnected the O2 sensor and it ran fine, other then throwing a CEL. Any ideas as to why it runs better disconnected? There were no previous error codes.

That's what i was going to do next, but thought it might be running lean with the O2 sensor. Causing the power loss and surging. Just looking for thoughts before throwing money at it.

nope, jumped it anyway to be sure, but nothing before. Was driving down the road a couple months back and lost power. Could stay in 5th on flat ground. It was mostly in the midrange and the tps didn't read in spec so i swapped it, but no change.

Keep in mind I'm no expert on the 3VZE, but I'm working on it.
