Transmision/torque converter issue?
I know on my daily driver 1.8L I had to unplug the electronic torque lock up or something along those line.
Unplugged it ~10 years ago..

x3 I had a 93 z24 that did that same thing and it was the lock up solenoid

x4 My dad had the same problem about ten years ago himself. unplug that bad boy first thing that will probably fix it.

I'm sure you did this, but how about the fuel filter? Changed and put in correct...not backward? Just throwing it out there< caused a similar problem for me once 😳

Well what the shop did was unplug the large vaccum line from the charcoal canister to the carb he just left it unplugged and said it was fine.
on the first test drive It ran perfect but after a little while I went out and drove it around and it was like it got worse.
Could it have been the charcoal canister being plugged? Because I left it unplugged till the next day it was still surging like hell then I pulled over and plugged it back on to see if that would do anything. But it didn't change at all. I see alot of you are pointing towards the torque converter. What about the torque converter could make it surge like that on acceleration.

Im going off memory here, but theres a lock up safety doo-hickey on those cars, and its pretty common for them to start malfunctioning and cause you fits. I was like 13 when this happened to my old mans cutlass, but i remember the guy that finally had the answer to what was going on looked like a genius when he just unplugged it and everything was fine. Lol wish i had more of the technical vocab but i wasnt paying attention to these things yet at that age. 😳

I don't think that was the problem....I'd go with the suggestion about the lock up may be causing it..

Ok I'm going to try it out but first can anyone tell me where this plug is? Lol the trans is a TH-350

its on the driver side of the case, it's easy to find unless you're like me and put a non lock up th-350 in your car. then you'll never find it.

Should be the only wiring going to the tranmission :idea:
