about 2 weeks ago, i got off of work and got into my car. everything was fine, started up with no hesitation. I drive 2 blocks down, stopped at a red light and my car just shuts off??!? I had to push it back into park, turn the key to off, and turn it back on. still no hesitation on the battery. No idea what happened, but its done it twice already.

only mods i have are ztube/popcharger,kinetix cats, and md 5/16 spacer. Car ran fine for about 2-3 months with those mods installed. happened out of nowhere..

any ideas?

 

Maybe a dirty MAS from filter oil.
Maybe a Vacuum leak.

Did it hesitate or anything before it died?

 

nope, i didn't even notice it shut off.. my car is usually very quiet when it idles. so i didn't even see it shutting off. next thing i knew, i pressed on the gas and i started rolling backwards the first time, and 2nd time, i didn't move cause i was on a flat street.

never really thought it would have happened to my car. My friend's mazda 3 had this issue few months back also. he said he cleaned the throttle body and it hasn't happened since.
