P1128 and P1130 success
Shortly after coming out of winter hibernation my CEL came on. Car is a 99 with 43,000 miles. Codes thrown were P1128 and P1130. The car was running well with the exception of a tiny stumble off of idle. I pulled the MAF and cleaned it but the codes showed as pending and CEL eventually came back. After searching the forum I learned that I could have among other things, a failing AOS (I believe that mine is original), a random vacuum leak - or a bad MAF. Since the MAF was simple to replace I started there. A couple of days later Amazon (by far the best pricing) delivered a new Bosch MAF and a new air filter. Problem solved!!! I passed my biannual emissions test yesterday. Idle is smooth and the little stumble is gone. I'm very pleased!!
