Vectra running lumpy/possible misfire

Asked by Marty1977 Nov 19, 2013 at 11:46 PM about the 2003 Vauxhall Vectra

Question type: Maintenance & repair

I have just bough a 2003 Vectra 1.8 Club, it runs a bit lumpy (idles up and down) it has a blown exhaust and the engine management light is on. I was thinking it might be a sensor but not sure, any help or advice would be appreciated. Cheers.

...might this be a hole in the manifold where the 02 sensor used to reside? That would make a spanky-mean bellow...can you look to see if the hole is the same size as an O2 sensor....these things gradually get eaten away as they take the careful measurements of the gasses present in the exhaust...they are important for determining the richness of the air/fuel mix~ this would bring on the CEL (check engine light) because the poor computer would not be able to compute the mix carefully...check for the presence or absence of the 02 sensor...and we will take it from there...thank your for the opportunity to serve you~~judge~

It's not an overly loud exhaust, but i do fear there is a blow at rear/middle and also near the manifold, I've not had a proper look as of yet as it's pitch black at the moment, but I will check in the morning. Thanks Roy.

Well I went out to the car this morning and it won't start, there's a picture coming up on the dashboard of what i can only describe as a steering wheel with an exclamation mark. Been told this may be because it's in "limp" mode. I'm nowhere near a hill and I've got nobody close by with a set of jump leads.


disconnect battery from both terminals after following manual instructions on how to disconect battery, then wait ten minutes then some how join them terminals together with tie wraps ect leave for 24hrs then after re connecting both terminals start engine and leave to run for ten minutes do not rev engine till ten min up this allows your car to reset every thing and calibrate its self this way clears all codes stored in the ecu and pcm ect


try checking the ECT engine coolant tempreture connector as sometimes vibrate loose cause problems like your on auto data says
