Relly tired off this problem now.When easing off accelerator the car is kangarooing******** and there is a bit of engine lag when i put foot down.Got code reader and cleared codes but it keeps bringing up different codes at different times or at the same time cant really tell as the codes are not present but the codes are usually 0300 random/multiple missfire 0300 (b)missfire detected at low fuel level (tank was full before you ask,always plenty of fuel.lol) and 0301 missfire detected in cylinder 1,please,please help.So far iv put on brand new coil pack and plugs,new fuel filter,air filter took out injectors and cleaned with carb cleaner all to no avail.The Engine Managment Light never actually comes on and car always starts and runs fine apart from the kangarooing********** when easing off accelerator or driving slowly like over speed ramps.
im thinking now maybe faulty ECU or fuel system problem (low fuel pressure or something)
thanks
