Setting P1020 and P1133

Setting P0102 and P1133

Started with a p1133. Bought a used O2 sensor from an ILGPC member that had 20k miles on it. Put it in, and the code went away for about 2 weeks. The SES would turn on and off while driving, and everytime I scanned it it showed the same p1133 code. Then, the SES finally stayed lit and never went away. After a scan it showed a p0102, along with the p1133.

So, bought a new O2 sensor, and cleaned the MAF. Codes went away....for about 2 days. Now they are back, and the SES light is always on. I show the p0102 is set, and a p0102 that is pending.

Are these two sensors tied together in any way?

Drivability is really starting to be affected. Under medium to heavy throttle, the car will buck and bog. Its progressively getting worse.

Thoughts?

UPDATE: the p1133 code is gone. O2 sensor is reading good now. The only one left is the P0102. Bought a new MAF today at lunch and will install it as soon as I get home.

Hope this solves it.

hey rich check for any chance that saltwater has crept past the seals in the metripack connector.

only by the fact the pcm/sensor grounds...the maf has a 5v reference feed that the o2 doesnt have, so possibly a ground splice or connection is dodgy...

did the new maf fix er?

MAF did fix the issue. Runs soo much better now. Cleaned the contacts on the connectors just for good measure, but they were super clean.

First start up after switching the MAF, the pending p0102 code went away immediately. Clear the stored code, and everything is good.

Thanks for the reply though.
