HELP!!!!!!!!

Whenever you spray an engine down like that, you always risk getting water into a connector which can really mess things up. What I would probably try first is get a can of air or electrical cleaner and clean all the connectors to be sure there is no water inside. If your computer threw a code this would make it easier as you would be able to figure out which sensor to try cleaning out first. Worst case I can think of is you permantly damaged a sensor and will need to replace it. I had something similar happen with my dad's 91 Ranger. I took it to the car wash to clean the engine bay out, got some water into the coolant temp sensor and it made the readings go haywire. I dried the connector out and the guage stopped reading like the engine was overheating.

This is why I now just use either a wet towl or a spray bottle of simple green. I'll clean off hoses, plastics and such and avoid electrical connectors.

This first: Anytime you spray your engine, cover your air filter, alternator, coil packs, basically all electronic stuff so that it does not get wet with trash bags. There's no telling what all you sprayed but it's probably water in your spark plug wells or the coil packs. One thing you can do that may fix your problem (assuming nothing is ruined) is to take a leaf blower and dry the engine very well then see if it runs better. Disconnect the battery too and re-connect it (i've done that before and it worked) ...

FWIW, every time I wash my engine, which isn't often, I have problems afterwards. That is with covering the electrical stuff I mentioned earlier. If you don't cover that stuff then I can almost guarantee you will have problems.

most times I have had problems was water got down into a plug and hopefully it didnt ruin the coil. After it dries out it should be cool. If not, check the coils and plugs

I've never sprayed any of my car's under the hood, always in fear of running into a problem. The most I do is maybe gunk a little, when first getting a vehicle, but, for the most part I clean it all little by little and by hand. Little more work, but, it'll be cleaner, and wont run the risk of damaging anything. Another plus, is when I clean my engine and compartment(3-4 times/year) I take my time and get it real nice, and in the process I spot any problems that may arise, ahead of time. Like vacum lines or hoses being bad, belt...wiring protection etc etc.
