I posted this topic in another section but I think it belongs here. I 4runner seems to hesitate when accelerating from stop when the engine is hot (i.e. stop and go traffic). It even died on me once but I was ableto restart it. The problem doesnt happen when cold or warming up from cold. Please help with any suggestions. Thanks.
I would bet you have a problem w/ your Mass Air Flow sensor. You might be able to clean it otherwise it would need to be replaced. Simple job--Just 2 screws holding it in to the air filter housing..Good Luck
