After having the head gasket changed about 1500miles ago, the car struggles to pull away, and it seems that the more you press the accelerator the less it wants to go.
Also, during acceleration between 3.5k and 4k rpm the car seems to lose power slightly and doesn't pull as much, then the ECU light illuminates, but can be made to go off by taking your foot off of the accelerator.
Anyone have any ideas what is causing the problem??
Haven't checked for the fault code from the ECu yet.
