way too low idle

ram15 · Jan 4, 2012

when i start my truck up sometimes the RPMs drop instantly to where it almost dies and from there it will go up and back down. i was thinking maybe it could be the injectors or something in the computer but i don't know. maybe you will, help me out here please.

Have you been using any oil lately? Could be the pendulum gasket.

go have your battery checked out
just had a problem like this my truck would start but the idle was to low and kept choking out the truck i had to keep my foot on the gas to keep it running then after a bit it would run fine and idle on its own then it would just up and choke its self out agin

This. Look down your throttle body for oil residue.

Maybe the throttle position sensor??

Your idle air selenoid on the back of the TB needs cleaned or replaced.
Or I'd start there. Run some good injector cleaner through your fuel system. Make sure you don't have any cracked vacum or PCV hoses.
