youcantkeepup!

Did you ever take it in or find a solution? I have the exact same gas pedal feedback as you, its driving me nuts. I have had a 14, a 16 and now the 18' all the same configs, CCSB. The 14 and 16 were flawless.

any one have an up date? mine still does it but i have found it to be related to hitting a bump. Will be 100% fine no ticking, hit a pothole or cross bumpy RR tracks (not like a maniac just general everyday bumps) and then the ticking starts.. might stop if you hit another bump .. might just randomly stop.. may continue until it sits overnight. there is def not a major power loss when its ticking but it also doesn't feel like it is running as good as when its not. My 2 guesses and they are purely guesses at this point since i am getting no codes is the core of the converter on the driver side bank has a crack or is loose and when i hit a bump it shifts and partially plugs the driver side bank exhaust causing the ticking sound as the pressure makes it leak slightly where the mani bolts to the head. The other pure guess at this point is (and i will check this on my own, maybe even swap wires) is i have been reading about spark plug wires coming off. Now i know i would get a code and drop a cyl if i lose a wire but if one is on the ragged edge of falling off the bump could jar it and the ticking i am hearing could be the spark jumping the gap to the plug

BUMP will also trade for new in box chrome handles

no, this is not the injectors, the previous few posts are confusing noises, this sounds like a leaky exhaust manifold tick... not the injectors

someone on ebay does powder coating with a wheel exchange so no down time

please keep me posted!

thats good yours does it 100% of the time though, then it can be fixed, its the intermittent that driving me nuts. i dont care there is the issue, things happen i just want to be able to get it fixed

thats aprox where min started as well.... I think if i have a load on it it does it every time after im a few min into my trive. I think i might hook up to my boat drive it some until it starts doing it then go right to the dealer with the boat hooked up to it and have a tech drive it

bump

i did not fix it.. it still was ticking away like a sewing machine this weekend towing my boat

so far it has been perfect, but it has not been hot here to duplicate results. its a bit louder on start up and for like 0 to 5 mph but performance is the same and fuel econ is the same as when the valve was active

dont have it done, i know i am not the only person to mention it but my gas mileage change when they did it. it is 1 or 2 mpg lower then it was before the peek in according to the DIC. Now, it may just have corrected that to what the truck actually gets, im not sure i have not done a hand calc but i do know by best 25 before the recall was 26.4 (long flat highway run) and my best 25 since the recall (all of 8 months now) is 24.2 along the same route

Ok.. putting some trouble shooting logic to this this morning (i am a mechanical engineer and worked as a technician all through college). Not sure about others but when mine is in ticking mode it def feels a bit doggy compared to normal. There is no doubt in my mind its an exhaust tick, i have had a gmt800 and 900 with broken exhaust mani bolts, i know that sound like the back of my hand! So with that said if you take the two issues, loss of power and the ticking, i see signs pointing to an exhaust restriction. I think that the exhaust flapper is sticking closed or partially closed (i have no idea how sealed the closed position is) . At this point i think i am going to wire the valve open and see if it eliminates the issue, i have a strong feeling it will.

Anyone have anything new on this? Mine was awful this weekend but it has made me realize it will do it all the time if its over 85 deg out. Sadly my dealer is not open on weekends
