The codes are in the area of the heated oxygen sensor ( exhaust manifold before the cat converter--codes p 0131 ,p1131,p1132)
code p 3033 is random misfires, code p0340 is cam shaft position sensor fault
the engine will run with heated oxygen sensor problems (HO2S) but will not run with a cam shaft position sensor problem
check for wiring problems then replace that sensor , ensuring that you have the correct air gap to the rotor clearance I suspect it is a wiring problem as I am guessing in that finding the sensor you were moving the harness around to see where it was and to get to it
in that case you probably made a good connection for a period of time and then it failed again

look for vacuum leaks the last 4 codes are lean codes
primarily lookm at the pcv hose noturious for collapsing

The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms

just tune up ur car periodicly, clean filter. clean ur sparkplug.
SOURCE: obd code p0133 and p01131
P1131 bank 1 indicates the fuel/air ratio is correcting rich for an overly lean condition.
Diagnostic Trouble Codes (DTCs) P0133 and P0153 indicates the response rate of the upstream HO2S(s) is below some calibrated window. The test measures the HO2S amplitude and output frequency. This is accomplished by superimposing a 1.5 to 2.5 Hz square wave over Lambse. The HO2S switching is monitored during this time to see if the calibration limit is met. P0133 is also bank 1.
Although these codes could be caused by several things such as vacuum leaks,fuel contamination,exhaust leaks,miss-fires,etc. Since it is localized on only bank one I would replace that front(upper in the exhaust to back cylinder head) 02 sensor and see if that did not correct my concern.

When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.
