idle surge?
So i clicked over 133K miles this week and now i have random idle surge. truck internally is stock... has a headers, intake, exhaust... which have been on for a few years..
The rpm will be a 800 then drop down to 400-500 for a few seconds then jump to 1000.. the air fuel gauge goes from 15.4 to 16.8 then shoot to 13.2 ish... then back to 15.8 or so.. and idel is back to normal 800... then a minute or so later it does it again.. But no always.. some days its fine runs all day with out doing it..
So would that be like a dirty fuel filter or what?

Mine does the exact same thing some times.. Could be a vacuum leak of some sort, but I am going to listen in on this post.. I have yet to find my problem, or a vac leak....
