So as the title says it's a 1994 4.0L and it stumbles when I accelerate and runs a little weird in idle, I already replaced the mass air flow sensor and not sure what to do next.
Got to do the basic... Any "CHECK ENGINE "? Clean air filter, Clean IAC (idle air control) at the top of the intake, Replace fuel filter (pretty cheap part), Checking for any vacuum leaks, and spark plugs and wires in good condition.
