well it stall. basically, as soon as i let my foot off the throttle, the rpm drop to below idle and the engine die. this happen as i coast to a stop regardless if my transmission is in gear or in neutral.

so i was able to limp it to the dealership. they said their feild engineer drove the car and attribute the problem to my aftermarket parts.

my car have Perrin crank pulley, ACT clutch kit, and AEM intake. they specificlly said unless i switch back to stock parts they are not going to warranty the parts.

as a result, I have made an arrangement with AEM to take a look at the intake before i put the stock intake back on.

here is a little mod history.

at 2.5K i have ACT clutch kit installed.
at approx 6 K i had perrin crank pulley installed.
at approx 10K i had AEM intake installed.

PS. after the AEM intake was installed, the engine response to a specific RPM range was shifted upward, for example, i usually pull 6th gear at 75 miles at approx 3200 rpm in stock form. while with the AEM intake, i am pulling the same speed in 6th gear at 3500 RPM. my corresponding MPG per tank does decrese by 1-2 MPG after the intake was installed. however that after the first unexpected stall happended 2 days ago, the RPM which corrosponds to the specific RPM seems to droped back to stock setting. last night i opened the intake cover to check for anything unusual, and nothing was found.
