Glad to join.

And could use some expertise in diagnosing an 3vz-e engine problem. I just had a shop rebuild my engine in Jan. 2023, in lieu or replacing the head gaskets for the 4TH time, (496,000 miles), considering a complete head vat, grind, surface & deck was required. Included, all parts OEM from YotaShop.com , : NEW pistons, rings, freeze plugs, multi- gasket, O-ring, seal sets, head gaskets & bolts, valve covers, timing belt, water pump, pulleys, tensioner, oil pump, fuel pump, fuel filter, salvaged fuel tank, fuel damper assembly, muffler, distributor, plugs, plug wires, battery, bearing sets, thrust washers, vacuum hoses, break-in oil/filter change, etc, etc

My 4ruuner starts, idles, and runs fine, BUT after running and warming up - engine starts sputtering and stalls upon braking to a stop, or making a slow 90* turn. I can quickly shift to neutral, & give it excessive throttle, and it starts right up and runs as long as I give it excessive throttle, including when I have to brake to a full stop. Prior to this behavior, for several months, it's 'Check Engine' light came on while driving a few times-But not every time, but after turning engine off and restarting - NO 'Check Engine' light, and didn't start stalling until now.

What could be it's problem? What to consider is the cause? Any input would be appreciated. Bobby

 

When I've had those symptoms in other vehicles, it was usually a bad fuel filter or failing fuel pump.
