Flat spot

[eco16v]

My c20xe has developed quite a flat spot when accelerating in 2nd and 3rd gear, is there anything that is likely to be causing this to happen?

Coolant temp sensors are knock weak points id replace that first - this doesnt show an error.

check the oxygen sensor is working properly if you have a voltmeter as well as they can play up and upset fuelling before ecu light comes on.
