yes another rogue petrol thread kinda.

i need lots of help tho.

car: felicia 1.3 spi n reg

last sat ngiht i filled my tank up with

must be far too complex for all you clever clogs out there then!

the o2 sencer should just skrew in/out. i would get a new one, then disconnect the battery for a bit (re-set ecu) and take it for a spin on the motoway.

thats what i would do but it is, in on way informed advice.

good luck

regards edd

i dont even know where the sensor is tho!

Had a car in last week showing misfires on all 4 cylinders, the plugs were white and smelt odd - replaced them and all was OK.

The sensor is screwed into the exhaust just after the manifold.

yer, between the manifold and the cat.

right. investigations later on today if the weather holds out methinks.

certainly badly misfiring, is fine about 2000 rpm if i dont accelerate, but any acceleration until 3000rpm gets very juddery and makes the car a pig to actually handle, but then between 3200, and 5000 rpm its pretty smooth, i dunno if this is because its spinning with so much more momentum, any misfires dont affect it so much?!

mine you, my old 1.3 spi did all of the above without the help of dodgy fuel.

Check out the ignition system first, the coil is prone to failure on these, as is the carbon brush in the centre of the distributor cap. Either of those things, or indeed faulty plugs and leads will give your car the symptoms you're getting.
