ANY BUYING/SELLING IN THIS FORUM WILL RESULT IN AN INSTANT BAN!
Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956
Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)
Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.
These are the rules. Read them. Live by them.
1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.
2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.
3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.
4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.
The rules can and will be added to. Any updates will be marked in the title.
The rules for the overall forum can be found here:

Originally posted by RedMagic187 View PostOkay that's what I figured just wanted to get a second opinion. I'm going. To try and do o2 sensor asap. Is it safe drive around with the car running so rich?? Or shud I park it up until I get the sensor.
When i drove without an 02 sensor on the freeway, at 65mph, my RPM was above 3,000rpm.
It did horrible on gas. After putting in my 02 sensor, at 65, i was doing about 2k-ish
Saved alot more gas that way.
Side note, reset the ECU after you put in your 02 sensor so the ECU can re-adjust to reading the correct emission.
