now my car loses power and just can't seem to pass 7000 rpm. It accelerates fine up until 7000rpm and then it just bogg. I floored it but it just doesn't seem to want to go past that rpm. oh yeah, its a 90 GTU.

Thanx

 

could be your timing...sounds like it's running lean at high rpms...

 

yea, i just replaced my fuel filter and like about 100 miles or so after, like i loose all power if i hit the accelerator hard and i hear a whisping sound outside like the engine is spraying air everywhere, if you figure it out, email me :soulbrothanumone@aol.com

 

You want to play craps like soul brotha numba one? Sorry

Are these OEM fuel filters? I've seen a few posts that say aftermarket fuel filters don't flow as well as Mazda ones. Maybe doing a search could help you out more. Good luck.

 

I got the fuel filter from Victoria British, I thought it was going to be OEM mazda but it wasn't, should i get the mazda one, and my o2 sensor is a bosch brand.

 

If the filter was installed where the inlet is towards engine rather than the gas tank, would the motor still run or does it flow in either direction, but less efficient if not installed correctly.

 

eom

 

USE FACTORY OEM FILTERS. It's been PROVEN that some aftermarket fuel filter cause bad fuel pressure
