Big trouble

[Teach]

Been awhile since I last bothered you guys. In Feb I had codes 410 and 1411. The car ran just fine and a mechanic was able to shut off the cel long enough to pass smog. other than the cel on all was well. Four days ago I started the car and was greeted with popping and spitting, it would idle but acted up when I tried to drive. As the car warmed up all was well and stayed fine (with several hours between statups)until the next morning when I went through the same process. I just got back from having the codes read and here is what I know: 410, 1411, 1124, 1126, 1128, 1130, 1140, 1316, 1317, 1318, 1319, 0300, 0305, 0306.

Anyone have any thoughts or suggestions? Any help would be appreciated.

I don't know where you live but in California you would pass smog for a couple weeks after a CEL. The DME has to record a certain number of "good" drive cycles after a CEL or it will fail.

Wow with all those codes the first thing I would check would be that the DME cable is tightly screwed on. The I would look for loose vacuum lines. A clogged fuel filter could explain the rich threshold faults and maybe the misfires but not the air pump. The air pump could be a fuse or perhaps it is unplugged. If the CEL is flashing you risk damage to your cats if you drive the car.

The first day, for a few minutes as it was really popping, the cel flashed then it went back to solid. The 410 and 1411 have been around since January. Just for fun and having nothing better to do last night I decided to pull the MAF and soak it in alcohol to clean it up. Amazingly the car has never performed better. My idle has risen from 900 to 1000 and it is was still a "little" cold blooded this morning (no misfire) but at this point I'll settle. I haven't cleared the cel yet to see if it comes back but it looks like another unexpected result from cleaning the MAF, weird.

Update: The car has never ran better. The only problems seem to be that it is running slightly hotter, closer to 200F rather than 180F previously, and at the higher temp the idle is a little uneven. I may invest in a new MAF just to see if it helps. I found the Bosch MAF for the 2.5 at autozone for $267 can anybody beat that price?
