1994 Service Engine Light
Hello All,
I have a 1994 automatic lt1 with 22k miles. Recently the check engine light has been coming on after about a half hour of driving. I checked the codes and it is showing two historical oxygen sensor codes (H13 & H63). I attempted to clear the codes with no luck. I figured that I would start by replacing the two sensors but I find it unlikely that both of the sensors would be bad. My only other thought is that there is a problem with the ecm and it may need rebuilt. I did some searching of past forums but haven't come up with a whole lot on useful information. The car seems to run great and does not feel any different when the light is on. Does anyone have any ideas or advice?
Thanks in advance!
