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.

        well of course your car is going to die after you go under zero rpms. lol but I dont see how a new header would do that.. have you tried installing the stock header on and see if it still does it?

          diagnose your CEL , but like said above it could be your o2 sensor

                Just dont let it go under ZERO rpms.

                And check your O2 sensor... its the one thing you took off from the stock header that had a wire on it. Unless you knocked something loose when taking off the stock header NOTHING but the o2 sensor could be the cause.

                But seriously its gotta be the O2 sensor or you knocked something loose when installing it.

                Then there is always the chance you didnt put the O2 sensor on the new header that little plug needed to be removed and replaced with the sensor from the original.

                Do you see the ENGINE light come on when your driving?
                We need alittle more information to help you.

                    Make sure everything is bolted up properly, gaskets are in, o2 sensor is in correctly and the other hole is plugged if that applies to your header. I dont see why your car would stall out because of a header install.

                      true...i don't get it too...
                      my other 91 accord didn't do that...
                      i'll just have to triple check...

                        The after market header likely has 2 O2 sensor holes. Which did you use



                        The top one or the bottom one? In other words, did you use the one on the header pipe or the one on the down pipe. You should use one that samples every cylinder, i.e. where all the gases converge, or simply, the bottom one

                        on the stairs, she grabs my arm, says whats up,
                        where you been, is something wrong?
                        i try to just smile, and say everything’s fine.

                          make sure the o2 sensor plug is snapped all the way i had that problem, but you might have blockage in the new header causing excessive back pressure. just an idea.
