Thanks for the update-I was just wondering how many miles you were up too a couple of days ago.
As far as the "pinging" problem you're having if your check engine light is not on I would start with a couple healthy doses of (reputable) fuel injector cleaner (such as Chevron Techron). Just be sure to "schedule" both doses for right before an oil change (I would run both doses back to back in your case).

Also if you have access to Shell brand gas I would try to use that exclusively or at least as often as possible. Shell has a well respected additive package.

I think I remember reading that you track your fuel mileage-any drop in fuel economy?

Thanks,

R2

I actually added a Gumout fuel system additive yesterday and filled up with Chevron fuel. So far, no pinging. The pinging was actually intermittent. But, I think the additive took care of it so far.

As far as my gas mileage. Yes, I have seen a decrease in it. I only get 36mpg with my a/c on. I use to get 44mpg when I now got the car, even with intake, exhaust and headers.

thanx!

new sparkplugs, seafoam the bitch and then do an oilchange. Clean that intake manifold right out. Do a can in the intake line... and one in the gas tank.

if there is a problem with carbon/gunk.. that'll fix it up. Seafoam is only like $8 a can.

New plugs, intake cleaner, and mass air sensor cleaner will be done this Saturday. I'm afraid to use any of those gunk cleaners.

thanx!

seafoam i believe is pure petroleum.... not weird stuff like acetone...

But, the tuen-up you have scheduled should help out I'd think... Good luck... looking forward to your next post when you hit 400k.

Here's Seafoam's MSDS: http://www.montanajacks.com/msds/seafoam-msds.pdf

It contains "pale oil," naphtha and isopropyl alcohol.

It's your decision whether isopropyl alcohol is "weird stuff like acetone" or not.
