Hey guys I have an 03 z/manual/111k with only a jwt pop charger (been on for 2yrs) and just recently sometimes when I'm stopped at a red light my z just shuts off out of nowhere an I have to restart her again. No check engine lights or any other dash lights come on. It runs perfectly fine when I'm driving regularly though and only sometimes occurs when I'm completely stopped. What can cause this? Spark plugs, alternator?

 

Anyone with any ideas??

 

You're going to need to hook it up to a scan tool with a glitch detector. That will identify what's not working right when the engine decides to shut off. Have you been keeping up with regularly scheduled maintenance (plugs, etc.)?

 

Check your MAf sensor.
vacuum leak?

 

mine did that a while back.
when it happened to me, it would shut off, then i'd have to let it sit for a few seconds, and then start it back up. but when it started back up it was like this:
then after letting it sit for like 10 minutes i could crank it up and it would be fine. hasn't happened in a while.. not sure what it was considering i haven't replaced/fixed anything.. lol

 

Got it hooked up and it was the cam position sensor in bank 1. Replaced it and all good now.
