fuel tank filter?

[brittanytvr]

Hello,
I have some misfire when turning to the right or left, also at around 1800-2000tr when the car run straight, perhaps electrical or fuel filter?? sparks, leads, extensions, distributor cap+rotor( lucas), amplifier, coil,relays.. are new and I have this problem since I have bought the Chim ( very low mileage, perhaps some corrosion in the tank and the filter could be blocked partially??)
I have changed the filter near the pump but have found that another exist in the tank, could I remove it without getting out the tank?
Thanks
Chris

I had something very similer when I had a failing coil on an old dolomite, if you know of anyone with a spare might be useful to swap.

You need to get the tank out to remove the filter, but I think it is quite an unsophisticated device and will not be the source of your problem. Additionally you will need a 52mm socket to get it out.

Another possibility (happens more than you might think) is that the loom between the ecu and the cylinder heads is chafing against the engine block as it runs up past the bell housing. This can cause a mystery misfire that is impossible to fix until the problem is isolated and the wires re-insulated.

I have changed the coil, same result

Thanks for the info, perhaps not a fuel problem!!

I would go with a wireing fault somewhere then, have you moved the battery or fuse box much recently?

[brittanytvr]

no, the battery and fuse box are in the original position!

Mine developed an occassional misfire - it turned out to be a loose connection on the ECU connector plug.

With the car running - pull out the ECU still plugged in and see what happens.
