'94 SES H64 code at idle
Got the car back on the road today after replacing the head gaskets. The car is running great. After the first drive I let it run while I got out and checked for leaks. Heard the engine sputter a bit then saw the SES light. H64 right bank O2 sensor lean is what I'm showing. I went for a second drive, ran great again no SES light. Let it run for a bit and threw the code again. Seems to be throwing the code as the engine heats up after sitting for a bit. Any ideas what could be causing it?
