Hi guys, I think there is too much air coming into my engine. When I'm in like 2.8 - 3k RPM's and hit the gas, engine just like chokes and car won't accelerate. However, there is no problem when I keep it easy and accelerate slowly. I have a Tsudo headers, exhaust with test pipe (just put on today test pipe), Cold Air Intake K&N and OBX throttle body spacer. Problems started after I got my intake. Do you guys think that my air filter is just too big and I should got something very small? or maybe its not enough fuel coming into the engine? Plugs and wires? I had the problem long time and finally wanna solve it.
