I don't really understand this so I was looking for some help just replaced motor with known good engine 3.8 new wires plugs fuel filter cam sensor new maf sensor. This is a 2000 camaro rs automatic. For some reason the evap and catalyst monitor won't ok.

 

p0300 is random misfire, could be a number of things, plugs, wires, coils, injectors. Just start with the simply stuff first..

 

Just had the icm checked 5 times its good
Replaced plugs
Replaced wires
Replaced fuel filter
Replaced cam sensor
Replaced maf sensor
Tested fuel pressure k/o e/o 50 lbs then dropped to 40 after pump stopped
Fuel gauge doesn't work
I was wondering if the fuel trim on the freeze data is normal

 

Maybe make a sticky if it isn't already??

did you check compression?

 

P0300 is a code that calls out a random missfire in ALL cylinders. If this is the ONLY code then it is rarely ignition related, it is usually fuel related. Check fuel pressure, Your fuel filter, run some quality injector cleaner in the tank for a few tankfulls (I recomend the 32Oz bottle of Lucas Fuel system Cleaner (it gives 6 or 7 treatments for the price of 2 of the smaller bottles)). Also check out your air cleaner.

Now if the data you gave was the freeze frame data when the code was thrown then I would also consider your o2 sensors as the trims were a little off from one side to the other. If your scanner does live data then take a look at the O2 data at idle and again at 2K RPM and make sure that both sides are pretty close. The odd reading could have been caused by the misfires.

Yes that was freeze frame data I replaced the fuel filter and I did run some Lucas cleaner through it I haven't checked the compression because I don't have a compression tester I had the fuel pressure tested with the engine off it went to 50 then dropped to 40 when the pump stopped

 

what is the FP when the engine is running at idle and about 2K?

Massey

 

I'll have to find out tomorrow after work but the car runs fine when its parked and rev the engine it only happens when I'm driving mainly anything above 2500 rpm

 

replace coils
