Had a chat today with Steve at Gasure as booking vehicle in for LPG

Whilst on the blower I asked for advice as to 'lumpy' running problem and he suggested checking the ECU coolant sensor by undoing it and shorting it out.
I did this and it made no difference at all. Does this suggest the sensor is foobarred

If so where's best to get one

Had a look on Brickwerks, but not listed.
Going to replace fuel filter as well, because I don't know if this has ever been replaced

Had a look on the Wiki and searched for lumpy running and got loads of good advice, but thought I would start with the above.
Would like to find and fix this, but I know the LPG conversion will sort it if all else fails

Sean
