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:

      Whats actually wrong with your car?
      You havn't described any problems that seem to relate to your current issue.
      Does it start?
      Does it start then stop?
      Or is it just not running right?

      If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.

            -Car won't start anymore, when it use to start, the car will bog at low rpm and it'll go away, or when i slam the gas, it'll bog all the way thru.

            You havn't described any problems that seem to relate to your current issue.
            car doesn't start, got sparks from the ignition system, and new fuel pump.

            Does it start?
            -it use to, but now it doesn't
            Does it start then stop?
            -it only did it once, right after that, the car never started.
            Or is it just not running right?
            no, it never ran right, like what i said, bogs on low rpm then it'll stop, half throttle - full throttle, it'll bog thru the whole rpm.
            all i know is that my ignition system works fine, and i have a new fuel pump

              How is the catalytic converter ? My 88 Prelude recently had a clogged cat and it acted like that.

                  Fix the errors shown by your CEL, and see if that fixes anything. Tackle the identified problems first.

                        Is it firing in the right order? I.e have you accidently switched the dizzy leads around?
                        Have you done a compression test?

                        Spark + fuel + compression + correct timing = A running engine
