Hello from New Zealand.
I'm currently 5000kms in from a complete ground up rebuild of my 2.3l, and now its having new problems.
While cruising on the highway in 5th, i noticed a slight loss of power - similar to the AC coming on. When pressing the accelerator to maintain speed, the engine felt labored and bogged, making a loud induction noise but almost no power. The engine still sounds in balance - e.g it doesn't feel like a misfire - more that its starved of oxygen perhaps. Closest analogy i can think of, is its kinda like starting a 2 stroke, but shutting the choke off too soon. You try and give it some gas, but it just struggles to rev.
If i cruise to a stop it'll happily idle and everything returns to normal. My girl friend has confirmed that this has happened to her also.
The injectors have been cleaned reasonably recently, and I've cleaned the MAF sensor also. Next step would be to pull the EGR valve and clean that. Last on my list would be replacing the PCV valve.
After that, I'm at a loss.
Any words of wisdom folks?
