Tom,

Have you pulled the plenum yet?

Can you verify all injectors have been changed?

Don't worry about the DIS yet. When I posted that last-night I was thinking about another thread, and posted on yours. My apologies!

Did you check for spark tracking on the plugs?

The kicker is the fact this started all of a sudden.......
Did anyone mention the MAP connection yet?

Manifold Absolute Pressure Sensor (MAP)

MAP Sensor Hose Fix TIPS
MAP sensor hose disconnected

x2 on the DIS for later.

No haven't pulled plenum,no tracking on plugs,injectors have been changed. I'm leaning towards coil,will do test with timming light test on wires & pull plug and check spark color. But before that will check fuel pressure,will keep you posted

Ok did a fuel pressure test full throttle 49-50,I assume that's good. Next I'm going to remove plenum and test coil pck

Loosened this bolts on the Plenum and radiator fluid is starting to come out is there a hose to remove the radiator fluid before I take the Bolts out?
