Steve,
Sent you a PM about setting up a time, as I do not have a vacuum gauge.

Martin, those are great ideas, thanks. The window in the carb has fuel right to where it should, but i will check for an obstruction before the filter.

Also, without a vacuum gauge Kvanoort and I were limited, but we did run the tests we could on the EGR Modulator and found it did not work due to a clogged filter. I removed the filter and it worked fine, as it should as detailed in the FSM. The EGR itself needs to be tested with the vacuum gauge and a foot on the gas pedal, for the reasons Steve described.

Thanks everyone for your continued suggestions. This is what you get when you go to add bling to a 25 year old truck :confused: nah, the lines I replaced were old and cracked, so this needed to happen anyway.

Carlton, did you try disconnecting the EGR to see if it would idle? Just remove the vacuum line from the EGR and plug it. To test the EGR, you can just "pull vacuum" with your mouth to do a quick test, it doesn't take much "vacuum" to engage the diaphragm in the EGR. :)
