Anyone have this problem before.......
My 95 Baja w/350 mag mpi's ran very rich after driving it for about an hour barely idles and black smoke out exhaust, but clears up after 2500-3000 rpms someone told me dirt in injectors.

"barely idles but clears up after 2500-3000," is a classic water in motor symptom. You should also check for signs of water on your spark plugs. Possibly leaky riser or gasket.

Check plugs all carboned up and somewhat wet (gas) Marina says he hooked it up to the scan tool no codes and all sensors working normal hopefully he's not lying, but I trust him.
I also heard might be VST getting clogged.... dont really know

Not a clogged VST. Clogged VST will idle but fall on its face when throttle is applied. My expierence anyway.

When they had the scan tool on it, what was the injector pulse width at idle? Thats the first thing you need to look at to see if the engine is being "driven" rich by a bad sensor or if it's a mechanical problem such as high fuel pressure, leaking injector, failed mech fuel pump, or overflowing VST.
