So i can hop in truck drive interstate speeds for about 20min. Get eng good and hot, stop to run in store come out start engine, it idles straight down and shuts off. Then if i dont feather gas pedal it will idle down and cut off while driving until i really get going. Cold starts seem to be fine, just having problems after a warmed up eng start. All new parts within last year, exhaust, o2 sensor, plugs, wires, air filter, fuel filter, timing chain, timing set at 5*. Seems to run fine, maybe lacking a little power. Problem really just started. Any help guys???

 

When you set the timing, did you jumper TE1 to E1? That forces base timing, which is what the 5° refers to.

 

Yes jumped terminals when set base timing to 5*

 

Any ideas?

 

Several have a warm start issue. Read this one: https://www.yotatech.com/forums/f116...-issue-288051/

 

Verify all vacuum hoses are in their correct locations.

Sounds like a temperature signal issue. Check coolant temp sensors.

Check air flow meter for a sticky air door..?

Air filter dirty..?

Idle speed incorrect..?

Throttle body dirty..?

Intake air leaks..?

Cold start injector fault..?

Air Bypass Valve(Idle Control) faulty and or dirty..?
