Ok guys here is the deal im getting a P1128 and it is making my car go limp with out always throwing th CEL. It is a 2001 roaster 225 with 32,000 miles my guess is MAF or upstream O2 sencer. I also get a secondary air pump CEL some time not sure what the deal is with that the deal test it and say it is ok. I think it is something that gets it reading from the O2 sencer but not sure. Any help or past expernce would be great guys. I bought a new upstream O2 sencer today the genral one and once i cut and soder the wires to put it on the car i cant return it.

 

Also does any one know for sure if the MAF is under an extended warrenty. Before i raise hell at my deal.

 

Ok guys no one has any option. Today i cleared my codes fild up my gas tank and put in a fuel injector cleaner. I also pulled my MAF and cleaned it with a can of MAF clean form autozone. So lets see if that helps. I will write back if that does not resolve the issue and i have to replace the MAF or O2 sensor.

 

I'm having this problem right now. I'm pretty sure it's my o2 sensor, but i havent got around to replacing it. If i clear the code P1128, then i get my turbo back for a while, but after a while the code comes back and my turbo goes back into "limp" mode. I don't think it is a problem if i just keep clearing it right now until i have time to get it fixed because it's just the bad o2 sensor giving a false reading, but if anyone can confirm that for me, i would appreciate it.

 

DTC P1128

(Never mind. I can't post the checklist.)

 

Had the same problem on a CPO 2001 225. MAF was replaced by the dealer and it only cost the $50 deductable. 2 weeks later they sent me a check for $50 indicating the MAF was covered by a service bulletin.
