So I cleaned my engine (5.4 1999) and now it's not running right it's rumbling and exaust is not a constant flow...whatcha thinkin?

 

Clean it again. You didn't get it clean!
You got water in the plug wells and on the coils if you pressure cleaned the motor.
They don't seal very well.
Good luck.

 

Pull all the COPS and blow the wells out with compressed air. Reassemble with generous helpings of dielectric grease in the COP boot. Cross your fingers that no COPS were damaged.

In the future, *NEVER* wash your engine with a spray *unless you are prepared to deal with the consequences*.

 

never clean engine I did that once major mistake...

 

I would say never clean/wash an engine, but caviat that with "if you don't know what you're doing". I've been cleaning/detailing my engine for uncountable years and uncountable miles on every vehicle ever owned with never a problem related to washing an engine. This one has 120,000+ and 9 years on it and it's always been kept this way, with never a failure...contributed to washing anyways.





I have two rules with washing an engine; no pressure washer and must have leaf blower. Use the blower to dry everything down good, especially along the top around the COP's/injectors.

COP's can get wet and short to ground without any damage. Just need to get them dried out good. Blow compressed air in & around them to see if you can get it dried out. That's the most likely culprit.

 

What's a cop? Part of the spark plug?
Sorry I went from a pos car that I didn't car about to a nice truck and I'm learning everything along the way ha.

 

Coil On Plug they took over plug wires....

I did the same on my truck and fried two cops. Never tried to clean the engine again. I would suggest getting on ebay and ordering all 8 for probaly less than 100 dollars.

 

These are several years old.. This was after a week of eating Idaho dust while camping



No way I was going to leave it like that!

Ended up like this... No problems either. I used a pressure washer, but the trick for me was to keep the tip at least 18" away from anything. At that distance, it's just mist. Enough to rinse it off, but not enough to drown anything.

I kept away from the top all together and did that by hand. I didn't spray directly on any wire harness connection either. There was some hand washing involved, but not that bad. The degreaser and the spray took care of most of the mess.
