I was driving on the highway and as i was driving the car felt like it stalled it, lost all power and i couldnt accelerate. the engine was still running becuase i shifted down to see what it would do and it did rev down and could hear the exhaust. i have a check engine light on for my intake it isnt stock its a short ram and in the cold i get a code for running rich and it started flashing. when i pulled over the car was still running and i tried giving it gas to see what it would do, it would rev to 3k tops and then start to choke at 3k. i tried putting it in first to move the car and it wouldnt move i thought clutch at first but it isnt slipping its the engine itself is choking out. i turned the car off then started it up again and it ran as if there was never an issue. any ideas?

Sounds like you may already know the answer.

Not sure how your region's temps have been compared to now, but colder air may have pushed your existing fueling issues into a zone your ECU was no longer comfortable with. Regardless, I would say you've gotten lucky so far and that it's time for a fix.

sounds like could be something with fuel system. injectors, pump, etc.

go see if it kept the code in memory. you can get a free readout at auto zone.

Get those codes scanned. You most likely have more codes thrown

That sounds like a loose Serpentine belt. I would switch it out first, if it does it again, your Tensioner may need to be replaced, I'm going to give you a little extra, $1000.00 worth, Ready? If you do this work yourself, make sure you use "Threadlock" on those bolts on your engine. I don't care if you tork everyone to spec., because of the high heat on these 4 cyl. engines the bolts without "Threadlock" will just start backing out and that's when things start snapping & breaking. Trust me!, good luck. Opps, this is an old question, but the answer hasn't changed, for you other members then. Best regards.

Flashing cel would not mean loose tensioner/belt. These cars have an auto tensioner. The belt will fail before the tensioner will.
