Kyllgore Yes I have replaced that hose with the better built and designed one

rangerbay No, sorry I confused you. The rubber tube crimped at the back of the motor. Did you replace it with the new style insulated hose?

Kyllgore the metal tube up front collapsed? I have already replaced the rubber hose for the collapsing problem and that helped a bit, I'll check it out again and make sure it's still on securely

crankcase vent tube. It starts out in right front as a steel tube, and under the throttle body, it connects to the rubber hose that goes behind the engine.
They collapse. I just had one go bad. No leak, just flat as a flitter.

Kyllgore alternator tested good, so I dunno what to do next

Kyllgore could the alternator be the problem? I believe mine is showing signs that it's going

Kyllgore sorry bump

Kyllgore ok PDFE sensor changed, new PCV hose
still have the issue checked all vacuum hoses all are good
what else should I look at?
Sometimes when it loses power I feel feedback in the gas pedal.
EDIT
Here is more info, car is usually fine at 1/3 throttle below 3k rpms
Over 3k it runs great, but below anything more than 1/3 throttle surges and feels like "popping" in the gas pedal.
So I doubt fuel is an issue and now from stops taking off I almost always need the AC off.
I need help can't afford stealership
would alternator effect this in anyway?
and for some reason this thread does not come up when I search?

why isn't my thread showing up anymore?

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.

I have severe loss of power below 3k, over 3k runs fine and normal.
So I figure it's not lack of fuel, I just replaces the PCV hose, it was
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.
