Hello,

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

It sounds like it's not shifting into overdrive. It could be the MAF not giving the correct signal to shift. What year is it? Is it an automatic?

Thanks for you answers,

It's a 1994, manual transmission.

360ci

I find the rpm change with a manual transmission a bit odd. What's the mileage on the truck? Have you changed the transmission fluid at all?
