my 2003 dodge ram 1500 after it goes thru gears and rpm's level out the truck jerks quickly then runs fine till I go thru the fears again
a hiccup? is that what you are saying? has nothing to do with fears, that was a typo, I got it. Had a tune-up at all recently? vacuum hoses kinda dry and cracked?
it's been awhile ( tune up) / hoses look fine. it feels like it jumps to neutral then back to drive in a half a second then runs fine till I slow down then go thru the gears again
pneumatic or electrical? pop-it valve or solenoid?
suspect a clobbered EGR valve that goes too slow because the exhaust carbon has slowed the show down....take the two bolts and connector off and give it a bath in brak-kleen, restore function with a couple of squirts of tri-flow, could test the vacuum or 12v operation to make sure it ain't retarded~
EGR is giving you the problem, not showing up as a MAF or MAP calculation error because it's just buggered up!
