Some running issues....Lumpy.....It had been fine....
I fitted an in line fuel filter and a new Temp Head Sensor.
I test drove the car and it was as sweet as a nut.....
The next day I tried and is still running a little lumpy....
After fitting the Temp Head Sensor I noticed the tickover was high...just under 2k revs.
I haven't changed anything else. Is this a duff sensor or the effects of fitting a fuel filter on the1.7 fuel injection?
I am pretty certain the filter is fitted in the correct place and the right way round!

Any suggestions....?
