Random Multiple cylinder misfire
I have been experiencing an random multiple cylinder misfire code P0300, on cylinders 1 & 4. I just replaced the spark plugs with a proper gap, all the coil packs because they were never replaced before hand and the car has 125k. You could feel it misfire under full boost before I did the ignition coils. Now its only throwing a code when im driving at constant speed, not accelling or decelling. I have no idea what the problem could be, egt's, icm's...... Any suggestions on a course of action would be greatly appreciated

Arrghh - I think its the O2 sensors
The car just threw these two codes,
16518 P0134 O2 Sensor Circ.,Bank1-Sensor1 No Activity Detected
and
16538 P0154 O2 Sensor Circ.,Bank2-Sensor1 No Activity Detected
And now its misfiring like a SOB on most of the cylinders, does anyone know where I can get the front O2 sensors for less than 145 a peice?
