Rough starting , will jump up and down then die, or it will idle but rev it couple times up and it will die. runs great freeway, come to a light fast and stop it dies approach slowly stays running, but might just be luck it is not Diesel replaced the fuel filter
Clean the throttle body and idle air control motor(IAC) on the side of it. Mostly the IAC and the hole it sets in. Also check the air filter.
Testimonial: "left comment ,below thanks Randy, Karin"
ok I will go try that , do I remove throttle body /Iac I know how to clean IAC not sure on body throttle Thanks for your help
Remove the IAC, not the throttle. Clean it inside with a toothbrush. Especially where the plate sits on the throttle.
ok thanks go do it now, will let you know what happens
Little better but still having trouble I took it for a drive rough going at start, then seemed to do well at lights, stop signs, no problem, when I turned into my driveway it died before I could finish my turn, now I turn it back on it does not Idle at all
I would like to mention it died turning into my driveway many times before today
Is there somewhere I can take it and have a specific test to pin point the problem I am a parking lot mechanic?
Ps sorry to bother ya, The ignition switch seems to have a little play in it, could it be an issue??

Throttle position sensor bad
Testimonial: "Thank You, very helpful everyone, but Ray, I mentioned that to a few friends, week ago they laughed me off. I will look into it between shifts Monday Thanks!"
Dose it have crouse control.or ABS If so you could have a problem with a brake switch or shout offcrouse control switch or even what is called the park pawl switch .
At ideal see what it dose if you hit the brake a few times then touch the AT shifter don't shift it see what happens to the rpms .The IAC gets a lot of information from this as well as the TCC witch controls the transmission shifting .They rum hand in hand RPMS and shifting .
Testimonial: "It has ABS I just replaced back shoes ,drums and the wheel cylinder 2 weeks ago.I will go out and see if I can do what you mentioned thanks, BRb...."
P.S. The brakes have hella play not hard or firm like I would think they should be??
Ok I tried that in }Park} It would not stay idled to try what you said, so I switched it to "Neutral" and it kept going, but in park it would surge{I Think} up and down then die.
but while in Neutral, I did what you said no change at all
Thanks for your help but I guess I did not fix it fast enough Tranny fluid leaking out pretty good by time I pulled into my driveway, so My issues just got bigger than my bank account. Thanks again
Sorry to here that Karin .However the transmission was a side effect problem .You see their are lots of electrical switches between the crouse control and ABS as well as the brake switch that control send signals to the transmission to tell it how and when to shift .You say you had the brakes done 2 weeks ago .No budy is trying to lie to you here but with out seeing the vehicle and doing testing its all experance dealing with similar problems .More transmission fluid would have not repaired the problem .That transmission holds at least 10 qt's Sorry about your problem mabey you should of asked the guy who did the brakes at least he could see it and put his hands on it

Fuel Pump Maybe??
Fuel filter maybe. But neither the pump or filter will cause it to rev up and down.
could the battery be going bad or ? the guage says it is charged but the needle jumps around sometimes
Not the battery. It would be the alternator. If the needle goes from around 14 volts down to 8 or 9 volts, Then this could cause a surge. But the surging would only happen if the voltage dropped. If the voltage stays up above 12 volts, this would be your problem.
This could be the alternator, but it could be loose wires at the alternator also.
Typo, If it stays above 12 volts, it wouldn't be your problem.
ok Just saw this thank you very much, but I did not fix the prob;em soon enough, cause yesterday on my way back from work tranny fluid must of got hella hot leaked out thru that round looking plug underneath the truck, alot leaked out. so now it just sits. thanks for all your help and everyone elses. Now I have no clue what I am in for.
