98 1.6 erratic tickover and poor fuel consumption - alanw47
Just had the cylinder head replaced on R-reg 306. Now it won?t tick-over properly and it?s drinking petrol. The tickover is very uneven and probably varies by 2-300 revs, running alright for a few seconds before rising and dropping. throttle setting is OK when driving.
The garage who did the head say they can?t see why it?s doing it. Any thoughts please ?

It needs plugging-in to see what the sensors are reading; but checking for air leaks into the manifolds and left-off/mis-plugged sensors [particularly the MAP and TPS sensors] would be a start.

Was it a new head or a second-hand assembly? Anyone checked the tappets?

Check the throttle position sensor. Mine used to do the same. I just unplugged it cleaned the pins and put it back together and it's been fine ever since. What do you call bad fuel consumption? the 1.6 should do between 35 - 40mpg.
