Brett,

you'll find the problem was a hose under the throttle body.
I can't remember if it is the PCV valve hose, it probably is. If the vehicle is still with you,pull the hose off at one end and see if the poor running condition is repeated.
If the engine ever suffers a backfire, it will blow this hose off.

What format are saving you captures in ?
I couldn't open them either.

These are pico diagnostic files showing cylinder balance and compression.

Hi Spence,
At idle it seemed ok it was only when you quickly revved it you could notice it ,then on the road under light load with slight acceleration or going up a slight climb you could also notice it.Also when i uploaded the files i too couldnt open them,what i did was open pico diagnostics program and load the file from where it was saved on computer when you uploaded to and i was able to get it to work that way.The file was uploaded to a temp file when you clicked on one of the 2 pddata files.Use Load from the file tab in that software to view.

Hence the pddata instead of the psdata? I'm checking my version now...

Hi Brett and thanks for answering my question. If you knew this during the opening post I feel you should of mention it.

Thanks again

Spence

Hi Brad,
There is a hose on the inlet manifold that goes to the throttle body and another smaller hose going from the throttle body to the purge valve from memory.The PCV is located under the plenum chamber and no hose directly connects to it.In the plenum chamber pics you can see where the PVC hole is in between the 2 middle cylinders.Thats where the blow by gases come in.All hoses did appear to be connected properly before removal.

Cheers Brett
