Dtc Po102

[chief153]

I recently changed the PCV on my `97 LaSabre, about a 10 days later I got a PO102 code. I removed the MAF sensor and sprayed cleaner on the wires and also spray the throttle body grid with the same cleaner. Driving only a couple of miles will set the code off again. I have tapped on the MAF housing and there was no change in engine operation. Strangely I can disconnect the MAP connector and get the same code. I have received excellent information from the moderators of this site in the past, so maybe you can give me some ideas on where to look next. My next move is to get a used MAF sensor and try that, before I sink $$$ in a new one from NAPA. The engine starts and runs as good as it ever did. BTW I made sure both the o-rings were good on the PCV and also the grommit on the MAP sensor is in good shape, I cannot detect any vaccum leaks.

May be coincidental but that code can be generated by the o ring issue at the map and pcv, but let's assume it is the maf, check as said for vacuum leaks, check the connector at the maf, then looks like it is bad. Avoid Cardone reman units.
