Trouble starting truck?

the A.I.R. system is the air injection reaction system, don't let the name full you, it has nothing to do w/ ur intake. it is a small compressor that adds air to the exhaust to help the catalyst change harmful gasses. it does not run all the time, mainly while cruising or part throttle. it will only effect your emissions so fix it before you get tested. it needs a fluctuation from lean to rich to work properly and it is normally located near the bottom of the headers in most vehicles. it may be difficult to replace on the 4.3 but i have never done one on a Chevy.
