ok guys i got my lt1 scanned today and it said that my left oxygen sensor has an error and it has exhaust indication and it says mass air flow circuit problem. if anyone can tell me how to fix this and get my car runnin good again i would be very appreciative

matt

 

the maf sensor is located on the air induction which will be easy to change out the oxygen sensor is located on the exhaust below the manifold. it might not be so easy. someone may can help you more on exact locations. i'm a third gen man myself and have never really messed with LT1 's . sick

 

You can try cleanig out the MAF sesor before getting a new one, as they are quite pricey. Clean the screen and hot wires with carbutator cleaner, but be very careful with the hot wires because they are very delicate. The O2 sensor can't be fixed, so you will need to get a new one. I had good luck with AC Delco, and bad luck with Bosch.

 

What where the error codes?

The two together could shed light on a issue that caused both...

As stated above, cleaning the maf, new o2 are the most likely solutions, just wondering what the codes where though.

 

yeah clean the Maf with a special electrical wiring cleaner
