I just replaced the upper and lower intake manifold gaskets on my mazda, in addition to the pcv valve, spark plugs and the corroded vacuum lines. I used fuel injector spray cleaner to clean the throttle body also.

I started it up and it ran a little rough at first, but then cleared up was running great.

I put in a small bottle of fuel injector cleaner, and filled the tank everything ran fine.

Once I got back home, I sprayed degreaser on the motor and rinsed everything off.

I started it up again and, drove out of my neighborhood it was running rough and then died, NO POWER the engine was still running but the car will barely move when I put my foot on the gas.

Could I have shorted out the coils when I washed the engine, I have pressure washed this motor many times before and had no problems.

Help...

Yes, possibly. Washing engines, these days, is fraught with risks. Try spraying coil and spark plug wires with WD-40, in order to displace any moisture.

If you have the V-6 engine, with coil-on-plugs:
