anyone here had the same experience? my truck is a ext. cab 01 nbs. put in pacesetter LTs no cats and cold air intake. i feel that the trucks is underpower and it idles low when engine is kinda cold or even on warm at slow speed. it happens when i approach speed bumps, reverse park or just full turns. i gas a bit, and then when i let go, it idles below 5mph to almost dying feeling but it recovers for a sec. i'm trying to figure out what it is, and am kinda trippin cause i think it may damage anything in the engine like piston timing or anything in the combustion chamber.:think:

thanks guys!!

My 04 used to do it stock, but the computer would always catch it and bump up the idle. Look at all your vacuume lines they moght be dry rotted and your exhaust probably isn't helping any. What did you do about oxygen sensors?
