My 87 4.0 idles right around there. it is an 87 and has a good deal of differences but its still a straight 6.

idle should be 700-750. Check the idle speed with a deferent tach. not sure it would run at 350 RPM.

Then the next guess would be check the Throttle position sensor djustment and see that the idle air control is connected.

If it doesnt idle rough, and it doesnt stall when you step on the gas(or come close to stalling) then i personally would just forget about it.
