Okay so here it is I wash my engine with the hose and I didn't cover anything because I didn't know I was supposed to I probably should have asked and looked it up before I did this was already raining I have a 2001 Ford F-150 4 ×4 . So I rinsed off a couple of things underneath the hood because it's always really dirty underneath there and I washed underneath the truck as well because ive had this bad oil leak, at least I think it's oil. It's not transmission fluid I know that and it doesn't look like brake fluid. Anyways it looks like oil. I just don't know if it's coming from the oil pan or from the four-wheel drive or the front or rear differential I just know it looks like oil and it's coming from the front of my truck. Anyways that's not my problem per say my problem is I washed the damn engine I let it dry for two days. I also took out the air filter and had it cleaned.< my husband did that> but I had to put it back in so I thought maybe I put it in wrong. So I pulled over and I checked it. it seems fine but the truck just runs horrible like it shakes now it makes this sound like I don't know a machine gun underneath the front like if you flick your tongue like that kind of sound. It's also running really low RPMs, I'm sure many of you guys are shaking your head but I need the truck for work and I've been letting it dry out with the hood open for quite some time. Also turning on the heater makes it shake 3 times worse. The way the engine is there's no way I can take all that stuff off to get to the spark plugs. I'm wondering if there's anything that I can do? I do notice that the oil leak that was just a few drops ever so often has turned into a much bigger puddles ever since I cleaned underneath it. Any help would be much appreciated my husband finds out that I took a hose to the engine and didn't cover all the stuff I was supposed to cover he's going to kill me he's also a mechanic and he's deaf and thinks that it's not so bad , but I can hear all the new sounds it's making and I can feel it . Please help me what can I do?
