I moved this post to the technical forum. I beleive that I posted incorrectly.

Help please,

I have a 98 Boxster Cdn model. Last year I had MAF issue and was able to verify that the Maf was bad by unplugging the MAF and having the idle and drive conditions return to normal. I cleaned my MAF per the instructions I found here and everything has been great since.

Three days ago I got the dreaded P1128 & P1130 codes but my car was running great. I cleared the codes yesterday and then tried to start up. I thought my car was going to die. It barely held idle RPMS and did not rev out of idle at all. More gas caused near stall conditions. The ECM never threw an new code. I went back into the engine compartment, cleaned and re-installed the MAF. I started up again and... the same issue. I then un-plugged the MAF sensor to see if this solved the problem or at least improved the problem and I have the same idle and performanace issue.

If the car threw a new code I would know what to do.

Was my sequence wrong. Should I try all the reapairs before resetting the ECM?

Does anyone have a good suggestion?

Anxious for you thoughts and to get my Box running again.

Thanks for reading and I hope to receive some good ideas and advice

Tom
