new 5.7 hemi issue

[whitehemiram]

after my other thread (wounded hemi) I tore the top end down replaced lifters, pushrods and rocker shafts it had a broken lifter on #2 cyl.
now it will only start with my foot on the gas it won't idle and the etc (red lightning bolt) is on been at this issue for 4 days frustrated enough to consider selling the other love of my life lol (my wife loves that). help please

The red lightning bolt means there is a problem with the throttle body. Did you clean it when you had it off? There also might be a procedure to reset it after you have disconnected it.

yes i cleaned it and I know now when I did my injectors I did not realize there was a procedure to drain the rails so idk what is wrong now lol

I would check the cylinder compression, you might have one or more push rods out of place.

just did that today at 2000 rpm runs smooth until you let off the gas I am thinking maybe putting the old rocker shafts on

 

[RonJon '06]

So it will run but only if you have your foot on the gas pedal? Are you getting any codes? What did you clean the throttle body with?

 

[whitehemiram]

throttle body cleaner does that matter?

 

[whitehemiram]

no no codes

That could be the problem. If you use anything but non-chlorinated brake cleaner and get it on the electronics the the TB might be toast. There are also a couple of procedures posted that tell you how to recalibrate the TB but I'm not sure which one is correct or if it needs recalibrating at all.

 

[whitehemiram]

oops lol I don't think I got it on the electronics but you never know. I also notice when it stalls its smoking out the tb

Here is a thread KBIGCOUNTRY posted in the DIY section.

The APPS recalibration is simple enough. After reconnecting the battery, the first time you go to start the engine. Turn the ignition key to the on position without starting the engine and without touching the accelerator pedal. Wait 10 seconds for the PCM to read the APPS value. Turn off the ignition, then start normal.

 

[Harley Harrold]

If the throttle body has been changed, cleaned, or reinstalled, the following
procedure must be performed:

a. Disconnect negative battery cable from battery.
Leave cable disconnected for approximately 90
seconds.

b. Reconnect cable to battery.

c. Turn ignition switch ON, but do not crank
engine.

d. Leave ignition switch ON for a minimum of 10
seconds. This will allow PCM to learn throttle
body electrical parameters.

ok left the neg cable unplugged over night tried reset procedure still won't run unless my foot is on the gas lightning bolt still on

ok here goes again I just pulled both valve covers all pushrods are in place rolled it over everything is moving fine.
first question I torqued my rockers to 23 ft lbs can they be to tight? it calls for 105 in lbs
#2 is there a way to test the tb
is there something I am missing?
thanks again for all the help
was going to order a new tb want to be sure I looked and there is not a used one within a hundred miles from me

 

[Harley Harrold]

105 in lbs. divided by 12 = 8.75 ft. lbs. so @23 ft. lbs. I would say yes you have a problem. The valves can't fully close. I would redo the valve torque asap.

oh crap I didn't even do the math dodge told me 105 inlbs/ 23 ft lbs

 

[whitehemiram]

so I went out bought a new torque wrench retorqued the rockers shafts. Motor sounds way better still won't idle

 

[Harley Harrold]

I sure thought the valve issue would have fixed your idle problem. Maybe someone else on this forum can get it sorted out for you.

 

[whitehemiram]

me too thanks again. I ordered a tb today mine is fluttering when you crank
