Mercury Cougar XR7 1996

Mercury Cougar XR7 1996 Have a 4.6 litre V8 with check engine light comeing on. This happened just after the engine was degreased and hi pressure washed. The car runs rough for a while like a car would run when there is water in the gas tank then runs fine after warms up. Still have check engine light on

Thanks in advance,

Put a scanner on it and find out what the codes are. This will narrow your search. You may have knocked a vacuum line or electrical connector off. Worse case, you broke or damaged something. Let us know what your codes are.

Sounds like wires are wet, most likely water in the spark plug holes.

I'd drive it a while, then check codes and reset light, will probably be OK. Pressure washing engines with electronic stuff is bad business.

All are correct.

Tip: No need to steam clean an engine like this. Not a show car and doing so does more harm than good for the everyday car. Leave it be .
