2003 Focus Loss in Power

For some reason when I hit the petal on my SPI, it makes noise, but doesn't speed up very quickly. It sounds like it's bogging. And when I rev it in neutral, it hesitates when the rpm's start to lower. I've replaced the coil and plugs recently as well as the egr valve and tube. Compression is around 230-240 in all cylinders. Could it be the egr solenoid or a vacuum leak somewhere?

No check engine light? Check filters (air & fuel) and PCV valve. Check the line coming off the PCV valve and make sure it's not cracked.

Hmmm.. This is how my problem started. And im not gonma say replace anything, but do the regular maintainance and of it does not resolve with that you may have the same issie that eveybody seems to encoumter with these engines. That bein said run a compression test

I do regular maintenance on it. And I did a compression test. Everything came out fine. My buddy plugged the car into his Snap-On super computer code reader and found the first O2 sensor to be off the charts, but not enough to throw a CEL.

Thanks for the help though guys.
