Replaced lifters and engine won't idle
Hello everyone, I change lifters on my 1999 1500 5.9l and after initial start up it seemed to idle not too bad but became worse about two mins after start up. Engine light came on and could hear a miss, and engine would stall at idle..to restart I have to push down on the throttle and then feather it to keep it running, but seems to smooth out around 2000+ rpm.
Repalcement lifters from NAPA.
All help appreciated.

Well first thing that comes to mind is did you connect all the plugs to the sensors and vacuum lines back correctly and are they seated properly? Especially the IAC and TPS on the throttle body.
2nd thing is, what are the codes from the CEL?

I assume you filled the new lifters with oil prior to their installation, but if not you could be having a collapsed lifter(s). Is the valve train making overly loud tapping noises?
