Just dropped in a JDM B18CR into my teg and the ECU is spittin out some codes. Strange thing is tho, when we hooked up the ECU to the Snap On code reader thing(cant remeber what this is called), it shows the rpm's going down when throttle is given. At idle, it shows at 700-750 RPM, but when the gas is pressed, it goes down...100-200 RPM. :thinking: Anyone seen this before???
