B16A2 Idle Stumble/Lag under 3k rpm HELP!!!!
Ok so I recently got a 2000 usdm SI with a B16A2. I noticed that when its cold it likes to stumble of feel like its choking when I drive it and this only occurs under 3k rpm. When its heated up it doesnt do it as often but will like once or twice a day. To make things worse when the a/c is on it has that stumble/choking thing even when the motor is warm. I fill up only 92 with Shell or Chevron which is good gas! I dont have any CEL's on.
Engine Mods:
*OEM Integra Type R Headers
*OEM Integra GSR Cat
*Greddy Catback
*AEM Short Ram Intake w/air temp sensor plugged in
*Fuel Pressure Gauge (which is at 40psi on idle)
Give me some advice or info on what this could be. Thanks
