Antifreeze level looks fine. Color looks OK too.
Nope, no rotor and cap, it has coils as you said.

I took it to the shop and they replaced the MAP sensor. It ran fine for a day or so, then acted even weirder than before. Very high idle while at speed, when i came to a stop sign, i put it in neutral and it revved to over 3000 rpm, eventually calming down to the teens.

I replaced the plugs, wires, and air filter. The fuel filter was rusted on and I could not (safely) get it off.

Now the check engine light went off, and it seems to run great!!
Also, a friend read the code and it was P0102, which could have implied the MAP sensor. But apparently the plugs and wires, and maybe air filter fixed it.

Also, the air filter cover was not secured, so air could leak around the filter.

NEXT QUESTION: How can I SAFELY remove the rusted bolt holding the fuel filter? (it is under the rear passenger door.)

thanks
