slightly better, happens after the engine warms up a bit too most times.
Having to over rev to start from a standstill is killing my MPG.
I'm going to start looking at the egr and dpfe sensor this weekend.
I had a check engine light last time, my car was in limp home mode
i replaced plug wires and coil and it was good, that was 3 years ago.
So what to look at next, vacuum lines all look and feel good.
My few engine mods are SRI and my TB.
Is there any sensors that need to be checked at 110k miles.
There's a big fat rubber hose I found today between the firewall and engine. Routed from engine manifold port, then routed from passenger side to driver side and forward near thermostat housing to a metal vacuum line system on bracket.

The car was bogging cause the vacuum was collapsing the soft rubber hose. I put some stiff rubber fuel hose in in place of the thin rubber oem part and car runs great again.
