Anyone else have suggestions?

 

I know this is a super old thread but what was the conclusion you came to? I not getting any CEL lights but I'm gettin similar problem with not as many symptoms. Mine is running lean and is not doing so well but once warmed up it runs ok, still running lean though. It just doesn't feel like it pulls as hard like it used to when on the gas, I don't have power loss like you do but I fear its only a matter of time. Hope you got it all sorted out I'm gussing mine is a sensor somewhere that is going out.

 

I've got the same issues.I'm in the process of fault finding.Have you actually resolved this?

 

Turned out to be a dead front O2 sensor again
The one i changed earlier was a cheap $35 ebay one which died a month later.
Got a Walker O2 sensor from oxygensensors.com, replaced it and the car has been fine ever since.

 

Is that the one with the cable going up over the tappet cover?Will you be able to pick up an error code with evoscan?
