Ok, not Vette related but LS based...Need your help
Have an 02 Silverado, 92k miles, 5.3
Repaced the battery today and upon startup this thing barrely wants to idle at 2-300 rpm. Is this normal, does the computer need to relearn anything?
Im guessing the computer is real similar to whats in you guys' C5s as the motor is LS based?
Radio didnt lose its memory....
Changed one out a few years ago and no issues, has always run flawless. Other than idle runs great. It doesnt idle "rough". just reeeeal low.
Well, in the C-5's and probably the C-6's, there is an idle memory function that the PCM calculates and uses. Normally I think it takes several start/run cycles before it finds the information it needs to make it idle properly. On the C-5's for sure, there is a idle speed memory procedure that will allow it to go into the idle learn mode. You will have to find out what that is for your specific vehicle. Disconnecting the battery can indeed cause that to be lost.
Started it 3-4 more times since. LAst time out it started and ilded in park Ok, went to drive and idled Ok. Got to the next tlight and went down low again and stays the same.
Ill drive it a bit again tomorrow, hope what you said is right. Never had a problem until I replaced the battery....Weird. Cranks over pretty fast, amps gauge appears to read normal. ????
KInow where I might be able to find this relearn procedure? Cant afford to take it in somewhere and dont have a FSM.
Warranty just expired, lol.
Well, day 3 and it seems to be back to normal again. ..Ill still get it checked for codes and clean the IAC and TB when I get a minute, sure it needs it.
