throttle surge

I don't know if this is the right place to post this, but here goes.....I have noticed lately that at low throttle start off (say from a redlight or stop sign) that the engine revs up briefly (like i gunned it). Its just a quick rev & gone, back to normal. Can anyone tell me what might cause this? or if I am even in the right forum? Thank's LHTC

Have you checked your trans. fluid level. Could be slipping a bit. A while back when mine was a little low due to a leak, when I would turn sharp corners it would do that. Just a thought.

I'm sure there will be others by that might have other ideas. Good luck.

Check the level first. If ok sit in drive and release brake does truck start to roll forward at all (should move at about 2-3mph).

Also if it does roll forward once it starts to move wait about 20feet and then press gas as if you were taking off and see if it still revs up. If it still revs after rolling and hitting gas it's likely te converter is on its way out or you have a bad clutch pack in trans. You will need to know the cvi numbers to confirm of internals are good or not.

here's the latest. Told I had a bad wheel hub bearing. Checked for recall. No recall for my Vin except for a transmission sump return line or filter or something. ( I think that is what they said). What is that?... Trk going to dealer Monday for the fix. Q?= Could this be the problem for my original post?............Thanks to the HTC & all members.

Yes it could be of it's air in the trans pump will cause a delay. Get that fixed and see of it goes away. There is a tsb for the 2003-2008 trucks for delayed engagement or hesitation on accel and it was the screw on filters causing that.
