stalling at idle?

[ebxgsxr]

ok, i have searched & read a couple threads where people have replaced their battery & everything was good. to give you some background.....idle for the truck seems very low. so low, it has stalled on me while sitting at a light a couple times. the truck starts back up no problems. but tonight, it stalled on my when i was trying to back up to get out of a friend's driveway. the RPM's go below 500 & i can see the battery voltage gauge start to drop. then it stalls. the threads i have read were saying to replace the battery & everything was good. but not the case for me. when i come to a light, most of the time, the voltage drops to right about 12 maybe a little lower. if i step on the gas to make sure the RPM is around 500-1000, the voltage comes up where it should & everything is fine. i would think the alternator is ok since when i press on the gas pedal to bring up the RPM's, everything is fine. but the new battery didn't fix it for me.


anyone know anything else i can check before i bring it to a shop?

Yeah, clean your throttle body!! Pretty sure that will solve your problem!!

X2 + disconnect your battery for half hour and connect it again but let it the switch on for minute before starting the engine

cool. i'll have to try that too. i hope it's something simple.

anybody else think maybe its the alternator? i mean maybe it cant produce enough volts at idle anymore? i would go to autozone and let them check the voltage on your bat and alty . its free

ok. i'll have to try that. but i would think that the alternator is ok since as long as the RPM's are around 500 everything is fine.

I think your alternator is on the same page as your engine...Its just following suit.

Did you clean out your throttle body?

When my throttle body is dirty, it does exactly what was described!! It's easy and relatively cheap to clean out, mine always runs awesome after a fresh cleaning, even if it's not stalling out from being too dirty!

 

[ebxgsxr]

not yet. i don't think i'll be able to clean it until this weekend. my 2 year old keeps me busy after i get off work. i'll try it & post here to update.

thanks for all the pointers/advise.

Maybe timing is a tooth off?
