Problems after installing extractors

Mazda Mantis · 30-04-2009, 02:40 PM

Hi All, I'm a newbie here so please bear with me

3 days ago I got "Wildcat" extractors and a 2" system put on my ba astina 1.8 hatchback and today the car started running like ****. Whenever starting to accelerate from idle (i.e. at traffic lights, turning corners) the whole car goes into a shudder and then conks out. After restarting the engine, I have to keep the revs up around 3500 rpm to keep the car from stalling again until I can get up and running. Spark plugs and leads look ok. Can anyone offer some suggestions? Do you think I need a Tune-up after changing the exhaust?

Sounds like it.
Do you know if your ECU was reset after installing the exhaust system? As it should have been to give the ECU a chance to relearn the new flow properties.

it could be as simple as they didnt plug the O2 sensor back in?

check the wire to it as well, if they cut/snapped it would have the same effect

and check the air pipes if you disconnected any for whatever reason

Or even if you didnt.
