Engine No Power
I have a Mazda B4000 and from a few months I saw me as the power of the engine decrease. I have much less power when the engine is on load. I also notice that the relationship speed/rpm is not the same. At first, in 2000 rpm, I drove 110 km / h and now at 2,000 rpm , I drive 90 km / h. Even if the check engine light does not turn on, I suspect the MAF to be responsible. What do you think?
Thanks, any help would be appreciated Vincent
