As to what the jeep is doing it is running rough at idle. It has done this since I got the jeep running after sitting for 10 years. I have replace the carb. the air tubes and parts. and other related items and no change. The only way I can get it to run smooth is to pinch of the second line on the canister (The main purge line). There are four lines going to the canister and they are no longer available from the dealer or anyone else that I know.
