72 RS camro 4SP

I have a 94 z28 when I first got it on the road about couple month ago when it was warmed up about 10 minutes of driving it would start running rough and getting a ses light on the dash would come up.So I disconnected the right o2 sensor the car was running great except for the ses light would come on after 10 minutes of driving and the cooling fans come up full blast and in fear that I keep doing that I will burn up the bearings on the fans.So recently I got a AUTOEXRAY SCANNER and connected the right o2 sensor.After a couple of days it has returned again with running rough.I scanned but came with a 52 error low oil coolent temp error?I cannot find it in the gm manual is it a fluke and I got no error on the dash.And intermentantly it runs good then it starts running rough most of the time now.

DTC 52 is not used for the LT1. There is no "low oil coolant" code, and the PCM does not monitor the oil temperature on the LT1 F-Bodys, only on the Corvettes.

What does your scanner show the right O2 sensor readings to be? What do the long term fuel corrections (BLMs) look like?

It could be the temp sensor for the coolant. If you replace it and the problem goes away the solution is cheap and fast. Repair costs on these cars gets expensive fast.

I ran another scan now I am getting 44 error a lean heated oxygen sensor on the left side error which could explain the problem.The oxygen sensor is connected good but it is getting beyond me to perform a injector balance test, a fuel pressure test even though it acclerates fine when disconnected and only happens after it is warmed possibly a bad left oxygen sensor but occured after 5 days and 100 miles of driving that it starting happening again and also no exhaust leaks?.
