At a guess, I'd say that the pressure wash has allowed some water to get into connectors. Get can of WD40 and pull the spark wires from the coils and squirt in the coil holes. Clean the spark wires with WD40. Any other connectors you can get at, pull and squirt. If the spark wires are old (5 years+), you may need a new set.

SOURCE: rough start and misfire

first of all you say you took out the plug you may have to replace the boot on the #2 spark plug and where you said it is fill with gas look at all of you injectors on that side and the fuel rail to make sure nothing is leaking at all use a flashlight when trying to find the leak cause its safer that way.

The boot/pancake seal that covers the spark plug cavity gets old and lifts off of the surface of the head. This allows dust and water to invade the cavity that the spark plug is recessed into. Moisture in the engine compartment will often find its way into the spark plug cavity and short the spark to ground (misfire). Sometimes moisture will cause the COP (coil on plug) to also malfunction. If you have even one plug misfiring, it is wise to clean all the cavities and replace the spark plug boots. You will need an assortment of 1/4" wobble extensions, universal, and 7mm socket to remover the COPs. It can be done without removing the FI rails. #7 spark plug will prove to be the most difficult. You will also need to disconnect adjacent injector and COP electrical connectors (easily done). Do not despair. Visually inspect each cavity using mirrors and contortionist moves. If you see moisture and/or dirt in the cavity, you should clean it out. Get a spray bottle with rubbing alcohol and fill the cavity about half way. Let it soak a few minutes and blow it out with compressed air. Always use eye protection when using compressed air. Inspect for cleanliness and repeat as necessary. A word of advice, do not hesitate to use the aftermarket COPs. They work well and are cost far less than the Motorcraft brand.

94 tbi starts but dies unless u pump the gas it runs rough


This could be a whole range of problems from lack of fire to engine to a bad fuel pump or pressure regulator in the TBI but if all of that is good then check the Cat. converter to make sure it is not plugged or the muffler. As I have 1994 Chev Silverado myself I know you can pull the 02 sensor out ahead of the cat. and it should run better not well but better. It will relieve the back pressure to the engine.

Could be gas related, Pump, Filter, MAF, Injectors. Could be Cat decided to clog, maybe a chunk busted loose and clogged the exhaust. Any number of things. I would suggest going to autozone or Advanced Auto parts and having them plug their code reader into the ECU and see if any codes are popping up. If the car is dying, you should have a check engine lite that has come on, especially since the car would have been running sluggish and probably rough or misfiring at some point. If not then you may be looking at ECU problems.

Check the idle air control valve. This sounds like it is not working right. it controls how much air the engine gets when it is idling. the pcm tells it to open more or close. they get old and dont respond fast enuf.

Good luck
