once i turn on the car its runs great, but after it warms up and everything i start to get a low idle and also it starts to bog out once i hit 4k+ rpms, recently changed the spark plugs and wires. Went away for a little bit and then came back. Anyone have any suggestions on what i should check out?

Not sure, but if you cant figure it out take it
to Williams Service Center on Bartlett Rd. They are good mechanics and honest ones. Talk to Ed if you go, he knows his shit.

If its starts to bog down at 4000 rpms I suspect a fuel system problem. At lower rpms its initial torque and a modest amount of fuel but at higher rpms its the engine and fuel doing all the work. I had a similar problem with an 88 5.0
Check your fuel pump its filter check your fuel pressur with a gauge. This is stuff you can do without spending any real money besides the gasket for the pump re install.
