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:

Read them. You will be expected to follow them.

    Loss of power

    Hey again everyone, I have a new problem for you! The car is an automatic '91 ex-r.

    In different gears at different speeds, my engine will missfire. I'm trying to accelerate when the speed plateaus and starts to sputter and struggle. I lift off the throttle then accelerate a bit faster and sometimes this temporarily fixes the issue, or just downshifting as if I'm overtaking will do it. In traffic I'd be forced to push the throttle and come off it when I know it's going to miss and just repeat the pattern until I can either speed up or come to a stop.

    This issue is recurring, but not frequent. I wonder if it's the oxygen sensor, spark plugs or plugged up fuel injectors.

    Any ideas?

    Your description sounds very much like an oxygen sensor problem to me. I would replace that (Denso or NGK/NTK only... no Bosch), and see if it fixes the problem. If it's not the cause, at least you've replaced a wear item that will most likely need to be replaced soon anyway.

    In the meantime, you could pull your spark plugs and inspect the tips. If they are bad, you'll be able to see it.

      Even if it is the oxygen sensor, I ahve a new one I never used that was supposed to go into the last cb7

      Thanks for the advice, now for the time to check it...

        Just make sure the sensor is for the right model. The EX-R will have a different location and plug than the EX and DX. (and if you happen to have a USDM model, it'd be the EX that has the different plug, with LX and DX being the lower models.)

        Also make sure the new sensor isn't a Bosch. If it is, don't waste your time installing it. It won't work properly. They NEVER do.
