Have the weber on the 2.4 liter 87 raider been on there for two yrs now erg light just came on I have the vacuum line on the top of the valve plugged do I need to run this line to a vacuum nipple or is it ok plugged first problem I have had with ERG light coming on also the line that runs out the side I plugged it also it has some moisture build in it when I removed the screw that its plugged with...... I guess my question is do I need to hook these lines somewhere to get warning light off or is plugging them ok...I have removed the erg valve and cleaned it it seems to be fine... thanks for any help
