1998 4Runner sputtering
I have 1998 4runner, 4cyl with 123K miles that has started to stall at low speeds and when idling. I am able to shift into neutral and restart it each time with no problems. It runs fine at normal and high speeds. I have changed the alternator, spark plugs, and had the fuel injectors cleaned. What else could be the problem? Is the fuel pump going bad?

Do check your fuel pressure. 38-44 psi
There are sticky posts at the top of this forum with links to the 93 FSMs. Fuel pressure regulator? Check these in particular: Just some ideas.
