the truck is a 1990 2.4l mighty max 1 ton standard transmission. when I bought it the clutch was gone the front passenger side was crushed in but fixed both, now when I TRY to drive it, keeps falling on its face I changed the mass air flow sensor, spark plugs, wires, distributor and distributor cap. it used to surge bad in idle but that stopped when I changed the mass air flow sensor.

the truck is in time, it does have a loose rocker arm somewhere, I haven't pulled the valve cover off.

I have read through the forms and haven't found anyone with my specific problem and advice would be greatly appreciated.
