linky for code p0154

linky for code p1153

i did a seach and it basically sounds like it could be:

MAF, 02 sensor, 02 sensor plug, spark plugs, spark plug wires, or option D: all of the above!

it all happened after getting on it (to 3k) after clutch install. idle is fine, but drops to 6-700rpm occasionally. 1200-2500rpms sounds/feels like its dumping as much fuel as possible and no power at all (feels like not all cylinders firing)

ive seen abunch of people with these codes but never these two together... anyone have any ideas/suggestions?!

ty all many,
cory

btw - WHODAT!

 

Looks like that o2 sensor could be shot. Check the wiring, connection, and sensor.
