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:

                  the fuel filter has been changed already.. the engine just got rebuilt when i first put it in the two ground wires on the thermostat were off and causing t not to run properly. the cel light was on also the d4 was on they got put back on and all lights went away the engine was put in 6weeks go and has 2k miles on it. it has tons of pressure from the fuel pump.. also the light only comes on when the gas light comes on is it possible im just too low on fuel and it runs low pressure momentarily...and could the d4 light be an old stored code??? thanx everyone

                    Code 43 is often caused by a bad oxygen sensor. Weird, I know. Does it come on when you get to about 55mph?

                      Error codes can be read from the ECU while datalogging, or by shorting out the service connector switch and counting the check engine light flashes.

                          Let me guess... it's an aftermarket o2 sensor from an autoparts store, right? Bosch?

                          They don't work properly unless you modify them. If it's not an OEM Honda o2 sensor, it won't work properly.

                            Stop letting yourself go low in fuel!

                            OEM o2 sensor is your best bet.
