Hi guys I had a problem at 40mph the car was hesitating at 40mph so no vacuum leaks and fuel pressure fine no misfiring too so decided to try to change maf and see what happens . I bought cheap denso 22680-AA310 maf the seller on eBay said it's original DENSO but in fact it's not but for 23$ not bad deal . after installed it the car was shifting at higher rpm but later worked fine but still shift at higher rpm than the oem by 50 rpm . no more hesitating at 40mph .

 

Not really easy to spot such a small difference in rpm. Otherwise, if the MAF you bought at 23$ was new, then it is an imitation. Imitation MAFs, if they work at all, usually last for 2-3 months but you may be lucky.

 

I have had good luck with WALKER brand MAFS from RockAuto.(WALKER PRODUCTS 2451138)
