I bought and replaced my MAF and o2 sensors, when the maf is plugged in and you start the car it idles good but when you Rev it up it smothers and drives real bad like it's drowning it self with feul, then when I plug it out the car idles bad but drives wonderful with all it's power etc.. .
I need some help also replaced the cvc valve, had some cracks in the intake hose and taped that shut not sucking air at all.
Please I am lost

Try to change the ICV with one from a donor car.It's next to the throttle sensor on top of the intake. You can find them new but the bosch replacement is quite expensie and aftermarket work quite poor.

I have the same issue as the first person with the MAF...Did everything... replaced spark plugs at first, checks the things that are on top of spark plugs (dont know english word) , checked the MAP and MAF sensors, cleaned them with maf cleaner but nothing... idles good but when throttling it holds back...
