I think I will try the heavier oil since the oil needs to be changed anyway.

Here is another update: I cranked it up this morning and it had a quick puff of smoke then it quit! I drove it two blocks out to the highway feeder road, took off and stomped onthe gas. It quickly took off, but the sputtered and almost died. Then the smoke started back again. I took it back home, let it sit for awhile. Cranked it back up and no smoke! Did almost the same test again, getting on the feeder road.... and it did the same thing as before... started sputtering, almost died and started smoking.

I think I am having an issue reusing the old j-tube. I noticed there are two different tubes listed for a 1999. With the original AOS, the old hose seemed to fit perfect. With the new AOS, I had to pull the hose REALLY hard to get it to 'click' in place.. and i'm not sure if it even clicked correctly (may hav a vacuum leak). How do I know which hose to buy? I think it asked for a chassy number, but not sure where to find that. Should I use the later number hose since the AOS is a newer style?

I'm starting to think I am still buring old oil out of the intake and exhaust. It sure is taking a LONG time though! You guys mentioned cleaning the MAF and throttle body. That looks like a simple task, anything I should watch out for? The MAF is the electronic part on side of the throttle body, correct?

Oh, another update.. the windows started working! I'm not sure why! It still thinks the key is in the ignition even when the key is removed however.

THANKS FOR ALL THE HELP AND ADVICE SO FAR!!!! I promise to help where I can in this forum as well.
