I haven't checked for codes yet. I hadn't gotten a check engine light so I didn't bother, but I'll check tomorrow. My O2 sensors were new as of last year, about 10k miles ago. I cleaned the MAF sensor it didn't help too much. I did try taking the stock MAF sensor and put it on the Pro-M meter. The engine didn't surge nearly as bad, but ran very rough. The only thing I haven't tryed is replacing the TPS. I have a spare in the garage, I'll give that a try.
