Ok, I get ready to take an hour and a half drive to my father's farm so I can work in the steel shop, I stop by my friend's house to pick something up and hang out for a while. Car was driving COMPLETELY fine. No noises, vibrations, nothing except the oil service lights. (I change my oil+filter every 3,000 regardless what instruments or dealers tell me) So I naturally ignore them since they are idiot lights and procrastinate resetting them myself. When I get back in my car and turn it on, the check engine light comes on and my acceleration is like my car was reduced from 6 cylinders to a 4 cylinder. It has about 3/5 the power it use to have. Naturally understanding how serious this could be, I only tested that once and took it REAL easy coming back home.
No new vibrations, No new odd sounds, (except MABY a moderate clicking noise at idle that seems to be at engine speed) No smoke or any other visible problems.
The only thing different is it does not have as much acceleration as before and the engine light is on.
I checked fuses, none were blown and I wiggled them all a bit to make sure the contacts were solid. Water temperature seems fine. There's enough oil in it and it's relatively clean. Radiator could use about an ounce or two of fluid, but water temp is normal. Brake fluid seems to be ok.
Normally I would simply go to a garage and have it checked out after I fiddle with it for a while. Problem is, it's the weekend and all of the shops JUST closed.
I'm going to take the little plastic cover off the engine that covers the spark plugs and double check those after I post this. I'd appreciate it if anyone could offer suggestions as I need to drive around a lot.
