Intermittent puff sound
Every once in a while when the car is warm I get the loud puff sound when I key on. Not when cranking just when I put the key to the on position and the fuel pump primes. It seems to be coming from the drivers side. I havent stood with the hood open and let anyone key on for me yet but I was just wondering if anyone else has experienced this. I should see if I can get a recording of it. Any thoughts?

i get the same thing every once and a while

the ignition is triggering a spark and igniting some fuel. usually cured with better cranking values.

If you want, move this to the ms section so anyone else with the same problem might see it. __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
it's been discussed.....it's especially fun when you disconnect your coils and try to start the car, then power cycle it.....

When it happened on mine I had assumed it was my wideband warming up & burning off some crap. It only happened a couple of times so I didn't really worry about it. Nice to know there is a fix.

Mine does it too, I would say maybe 10% of the time when I am about to start the car.
|
mine just backfires when it's extremely hot/cold and leaves a black spot on the car behind me :)
