tell us..me more.......vehical specs...what it is exactly doing...anything...haha

 

Huh? What?

Sorry, but I don't understand this sentence...what is meant by "veh"?

What is meant by "acclerated foot on brake"???

Are you having to put your foot on the brake quickly because of how fast your 4.2 is? If so, tell me what mods you have done, as I too have a 4.2; while it's not fast like the 5.4, it does get me down the road just fine, and pulls a trailer once in awhile without any major concerns.

 

.....haha i have no clue...im guessing he meant ...Vehical accelerated while his foot was on the brake.....but i guess he fixed it or was a new poster drunk as cudi brown....

 

Sounds like that may be what he was talking about lol.

Ya know I thought I felt my truck jump foward when I put my foot on the brake after I parked once, but I'm not sure if i was just tiredor what.

 

haha....well actually ...i wish eh would tell me more......the other night i was pulling up to a 4 way stop and it was raining...and i had my foot on the brake and my truck started spinning and felt like it was missing...i was super tired..i thought my foot was on the gas and it maybe it was just wheel hopping......when i got home i parked in the yard and when i stopped it started spinning and i new then that it wasnt wheel hope becouse of the wet grass............2 days later i got pulled over and it didnt it again and when i stopped completly my truck died (like iw as driving a manual and didnt use the clutch)it was bucking and stuff....cop thought i was drunk becouse i killed it...i was like its automatic.................soooo.. i think its somthing in the tranny going to the shop monday..unless it goes sooner on my car trailor...ahaha

sorry for long post....

 

we no under stand ques

 

x2...haha maybe its some kind of code... i bet he got kidnapped and is telling us where to find him

 

This is a much better (edited) description over your first post...

Was there ice on the driveway? Did your wife allow the truck to warm up once she started it, or did she just start it up and then put it into gear (reverse, then drive)? I ask because the engine will have a high idle in cold weather when it is first started. It will not "idle down" until it has reached a certain temperature.

In the cold month(s) of Texas weather, I will start my truck (also a 4.2), and allow it to idle until I detect the engine has warmed up (the idle drops); usually about 45 seconds. I then put it in gear and drive off. I will do this in warm months as well, as I don't like to drive off on a cold engine.

If there was some ice or snow on the driveway, or she put it in gear right after startup, the truck may have "lunged" back/forth because of the higher revs during warmup, and the rear wheels perhaps spun.

I would agree however that it should not have screeched, and taking it to a shop to make sure the "drive by wire" setup that our trucks now have is not sticking or causing an abnormal high idle. Safty first.

 

Haha So you basically did a brake stand for the cop? Sounds like you have some kind of throttle issue to me, not a transmission problem
