91 Toyota 4runner stalling
\015 My 91 toyota 4runner keeps stalling out and shutting off. Can be idling or driving. Fuel pump is fine. Relays have been replaced. I'm thinking possible fuel filter but it doesn't happen all the time. It takes spells doing this.\015
Try to clean the Throttle body of your engine I believe you never did, Also check whether you have also Air Flow Meter which is situated on the Flex Intake Hose of the engine.If so remove it by disconnecting the connector and remove the 2 little screws. Take it in your hands and check the inside where on the one side you will see a small wire surely would be covered on dust. By means of carburettor Cleaner give it a blast after you remove the "O" ring first.Give it a try.
