The car shuts off when you come to a stop. It drives great but shuts off when your at a complete stop. I guess there is too much air going into the engine.. In Park it idles at about 1K then i push it up to 3K and let it sit and it goes very close to OK and you can feel the car shake alittle and it goes back up to 1K. This sucks tho, now i have to put everything back together, unless i come up with something that will allow less air to get in. BTW i used a 3" tubing, and a 3" cone filter.. dunno whats wrong..?!?
