Misfire?
« on: 14 July 2013, 11:29:01 »
Hi, When I accelerate at low revs the car seems to misfire, I have changed plugs, air filter and petrol filter, when I was under it I noticed that a couple of wires had been pulled of the exhaust sensor, could this be the problem?
When car starts to misfire if I drop it down a gear and give it some revs, its fine apart from being expensive on juice.
Any ideas?

Coil packs or plug wires?
Very similar situation on my 97 Cat turned out to be a plug wire shorting to valve cover.

If you have wires missing on the sensor you need to sort that before doing anything else in my opinion :y

Do Lambda sensors (non working) cause misfiring then?  :-\
