Seriously though, you mention noise and a feeling.........which is it. If you mean it's running rough on tick over it could be a multitude of things. My car did the same when it got a build up of carbon in the engine, ran ok - but ticked over like a bag of spanners - made the whole car vibrate, or 'rumble'. May be worth trying some Forte Gas Treatment. A Mazda recommended fuel system treatment. |

cheers rich, i'll give it a try, but it only does it when cold thats why i thought it could be a choke sensor or something, its hard to describe but it kind of chugs on tickover but if you rev it it whines beutifully. after 5 mins it runs perfect. if you look at the exhaust when its just been started its a kind of sequential smoking, not continuous. i dont think its missing because on a run it would be noticable but it isn't hope i haven't confused ya

| Post subject: | dodgy tickover |
my car does what rich described drives fine but is rumble and makes the car shake at tick over and it gets worse as the idle speed drops as the car warms up could a dodgy ignition lead have anything to do with this? |

I had exactly the same thing ... when starting my car from cold it soundes almost like a skooby engine, which was quite nice, but wasnt right. After a few minutes the car would drive fine. After months of mulling it over, I fanaly found the problem. I noticed a spark coming from the Dizzy cap... aha I thought dizzy cap has a crack in it.. nope - One of the leads, which were only 2 months old, has lost its end and the spark was flying across a gap causing the engine to idle strangely. Check your leads, and if its not them, check your dizzy cap for cracks . |

sorry gogobroom . when i had me 'donor' 323f i swapped the dizzy n leads over from that one and it still run like a bag of w**k on tickover. so i may try redex in the fuel but ive heard it makes ur car crap on fuel because it opens the injectors up..... am i right?? jamie |

i had something similar, but a quick mess with the ignition leads sorted it. i thought it may have been damp in the chamber where the spark plugs are, but it hink it was a loose lead. doesnt do it nemore |

My dads got the same car so i nicked one of his ignition leads n swapped it for mine seems to of made a bit of diff n i knw its not the dizzy cap cos its brand new i think wot rich said bout a carbon build might be right. Also wen i had my custom exhaust fitted they guy said cylinder 4 wasnt runnin right so i checked the plug an it was really sooty any other ideas? Cheers Pete |
