97 corolla almost stalls taking left turns - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 97 toyota corrola with a 1.6 littere engine 206k miles. It almost stalls while im taking left turns intermittantly. It has no codes and Ive watched the data stream on my scanner. All the sensors are good fron the tps, map, IAC, coolant temp, IAT, Even the fuel trim is good(that was my first concern) Im ripping my hair out trying to figure this out....Please help!

I have the same problem, mine only happens above 15mph hard left turn. You can turn it any which way parked or at idle and it wont reoccur.

Fuel pump is on the left side of the tank, and when you make left turns the fuel is running away from the pump/pickup. Does it make a differences with the amount of fuel in the tank? If it gets worse when it's lower, your fuel pump is likely wearing out or the screen around it is clogged up.

I'm pretty sure its some kind of fuel pickup problem. Mine has always done it, even when I replaced the original pump (it did fail), the 1st one was loud as hell and died on left turns like it used to do. Got a different pump, was quieter and left turn problem still. I tried different fuel strainers and installed the pump a few times, I could watch it go dead lean on the wideband and checked that it had constant voltage. I think somehow the well that the pump sits in sloshes its fuel out on left turns and then runs dry. It can happen even on a wide left turn at higher speeds, its related to lateral G's not the sharpness of the turn.
