I got a check engine light on my 2001 with about 35or 36k miles. Same codes as you, checked all available resources on the web and figured I would try cleaning my MAF. You have to buy security torx if you are going to do this, I found them at Advance Auto Parts. Cleaned the MAF, disconnected my battery for 15 secs to clear the light and it didn't return. Until about 2k miles later. The car seemed to throw the light when I was in stop and go traffic in hot weather w/the AC on. I checked the codes again, P1128 and P1130 and was going to take it to the dealer, but the light went off while driving a few days later.

Took the car to the dealer for unrelated matter and they informed me I needed a new oil filler flex neck and clamp. My warranty didn't cover "hoses or rubber parts" so I declined the fix and would try to tackle it myself. I found the spring clamp on the oil filler tube that attached nearest the engine was kind of crooked and the tube was not snug. I took some channel locks, took the spring clamp off, pushed the tube all the way on and replaced the clamp with a screw-down type (or whatever they're called.) It is my opinion the dealer could have taken 5 seconds and fixed this, but told me I needed a whole new oil filler flex neck for the tune of $350.

No CEL to this day, knock on wood. I would check for vacuum leaks before doing anything, it could be something simple as what I had.
