tps evaluating for ii issues

[max]

Thanks for the input guys, i like peter's idea about the valve, i found a picture that explains where the vacuum lines attach, i guess you want to take off the hose at the back that is hard to get to?

the valve is the blue/silver thing on the top right without cannister hose.



i wonder when this valve operates, can we make dave's life easier by disconnecting the hose at the front and opening the valve?

Actually looking at the picture is it not easier to pull one of the outer vacuum hoses off the throttle body if it is just the effect it has that we are after?

Also wondering if we should look at o2 sensor voltage at some point?
