Well, I got my Libby back.
I took a road trip for a 100 mile round trip. Used 5.335 gal for an average MPG of 18.74. 10% was city. The check engine light never came on, but Ed the mechanic let me take his OBDII code scanner home with me, and he told me to drive it with it linked. At the half way mark there were no codes. I stopped and went into a store and bought some snow chains for the Reno trip, and when I came out, I synced the reader, and then started it up. It threw a code. P0303 again. I cleared the code and drove it home without idling it. Luckily I hit all green lights. Then I stopped and got gas. I had no codes, and then turned off the engine. I synced the reader again and started it back up. It threw the same code again. The check engine light never came on. With the code coming up, why wouldn't the check engine light come on?
Also, it is idling rougher than any vehicle I have ever owned. It is idling at 600RPM again. If I give it just the tiniest bit of gas, it smooths right out. I think for now I am going to have to call it good. The engine now has 232 miles on it. What would you do? I think I'll run a full tank of gas through it, aprox 300 miles, and change the oil and I'll be ready for the trip.
Besides the rough idle, it runs great! LOTS of power and near 20 MPG on the 101 Pacific coast Hwy, with all of the hills and curves, that is way better than I expected to see. I would be willing to bet I get closer to 21 MPG when I get to the interstate.
Oh, I almost forgot to tell you... I found the whine problem. I changed the alternator, started the engine for 5 seconds, and it was still there. I went back and returned the alternator, and bought the two pulleys on the tensioner. $40 bucks, and three minutes later, I had her licked. It was the smooth pulley's bearing. The grooved one was still good, but figured I may as well replace them as a pair. Now it runs as quiet as a lamb. :Hump::Hump::Hump:
