Does it backfire all the time, or just occasionally ? Mine often gives a very satisfying "POP" when I'm thrashing her and I drop the clutch and change into the next gear ...

For a while now my car has been backfiring. I do have a Ø50mm (2" est.) exhaust system with the standard maifold. Is my 180se Astina's Fuel mixture too rich? My timing is set on 11deg advanced? Is this serious?HELP! |

Mine is currently broke - hole in the middle box - that pops every now and again - it's little amounts of un-burnt fuel igniting from the heat i think... |

Only occasionally, but if I rev her while in neutral the exhaust gives of small little backfires. |

Could be down fuel mixture. Do you have an FSE PBV? I know when I fitted mine, I had the mixture a little high on the fuel side - that made the exhaust pop quite alot! L8rs....... #;o) |

[quote]Do you have an FSE PBV? [/quote] Mind me for asking, but what does the above stand for? |

Apols! I almost knew that was coming! Anyways, stands for Power Boost Valve. The FSE is an adjustable fuel pressure regulator that replacees the standard un-adjustable unit! http://www.club323f.com/ba/tuning/fse/fse_fitting.php ttfn Phil

Nope! Have none of them fitted. Maybe I should take my car to get the CO mixture checked? |

Rather get a Unichip fitted, and get the mixture dead right across the rev range ... |
