Hello, I have recently got an obd2 code of P0102 "mass or volume air flow circuit low input" on my 2002 Buick Lesabre with a 3800 motor and 130k miles on the clock. After the code was set I connected my scanner and monitored and trended the signal while driving and what I noticed was that the sensor appears to be reporting the correct air flow rate but intermittently the signal would flat line for a few miles and then return to operating normally. The car does not idle real smooth and has an intermittent miss also at idle but otherwise seems to run okay with the "fuel trims" normal. I have removed the sensor and inspected it and visually everything looks good, also checked the power and ground wiring with a volt meter at the connector and all checked out okay. So I am looking for any advice as for anything else to check before I throw a new sensor at it. Any thoughts would be greatly appreciated.
