Hi, I am looking to get some advice on some CEL's I cannot seem to resolve. Ive got a quick breakdown of what I've done and whats happening now.

I am pulling out the following CELS

P0300
P0037
P0302
P2004

I put four new coils in and the cat was removed and test pipe installed. I dont figure the rear o2 should cause any starting or running problems

The car will not start, I have pushed started the car by pushing it down my drive way, it fires up and runs, however it pours out smoke and gas fumes, will not rev very high and dies when I let off the gas. I have had the de flood treatment done aswell.

Any ideas on a solution here?

Also I have reset the ecu/ecm KAM and the NVAM or whatever didnt seem to help with codes and running conditions

Year of car? Miles on engine? Last service? Do you have upgraded starter? What methods did you use to reset KAM/NVRAM?

Check list:
Spark plugs/wires
Air filter/MAF/eccentric shaft position sensor cleaning (followed by NVRAM reset)
Battery connections/test

/\ What Soldier said.......

You definitely have fouled plugs, and probably a bad intake air leak - the O2 sensor sees lots of oxygen in the exhaust and dumps loads more fuel in.

thanks for reply okay,

Ive got new plugs installed, new air filter, cleaned maf, changed oil and filter.

reset by depressing brake, and then i did the odo reset into test mode and then back off.

tested battery connections are strong, tested spark at plug okay, have old style starter, car has always been slow to crank but has always started. had the de flood treatment done about a year ago. car is 2004 with 69k

also wanted to note, when changing plugs the two on the first rotor were soaked with fuel.

You should probably consider upgrading your starter. Sounds like you are getting too much fuel in your engine.
That said, there could be an issue with your fuel injectors.

What do you mean "depressing the brake" line? Is that how you reset the KAM/NVRAM? If so, that only works to clear the PCM. KAM/NVRAM method is to turn key to "ON", press brake pedal repeatedly until oil gauge sweeps. You can also unplug battery for 20min and hold brake down to drain the juice.
Both those methods will cause unstable idle for a few drive cycles.

Wow - messed up eh?

P0030 Front HO2S heater control circuit problem
P0037 Rear HO2S heater control circuit low
P0302 Rear rotor misfire detected
P2004 APV stuck open

I will likely do the upgrade but. I don't believe that is the problem. If it was the car would run after it starts which it doesn't. For the resets I did the, key on. Depress brake and oil gauge sweeps and key off. I also held the odo reset, key in, test on. And repeat to test off. I'm not sure either I feel like a injector would throw a code. I suppose I could swap injector to the rear rotor and see if the plug reflects the changes? I don't think having the rear o2 problem is going to cause any major afr changes
