My car is feeling a little weak

[ghosts14]

I have recently changed all the usual items, but my car is still feeling like it just not pulling as hard as it used too. Is my car on the way downhill? What can I do to help the car regain some of the good old feeling?

you might wanna get you compression checked, that'd be where i start

try the engine flush thats in the faq section. it seemed to do me some good.

I would re-check the fuel filters, the AIV and MAF sensors. Make sure that the O2 sensor is functioning properly. 93 octane sometimes helps (barely).
