I feel like my 05 wrx is loosing power. Getting around I traffic is causing me to rev it over 2000 rpm to what I feel is safely get through intersection.
All maintenance done regularly
Just had Subaru do plugs, PVC valve, trans oil, diff oil. Brake fluid (month ago)
I checked the MAf and it's clean, air filter is clean, fuel filter is in tank
I've read timing belt should be done soon, but I can't see that affecting power. Idle is fine. I would think if I am loosing compression subaru may have seen that. Is it the heat? Anyone know the power loss from AC. I'm ready to start tearing into things looking for clogs...
