Just want to know what your MAF voltage is at idle. Trying to tune my car with an IST Air Adjuster, idle screw on the throttlebody and a wideband A/F sensor. Before the Air Adjuster my car would die at idle and when coming to a stop. Also, at no load/cruising speeds the car would studder really bad. So, the car was running way too lean apparently. Okay, so now the car can idle with this adjuster on there but I am not sure about the MAF voltage. And, at idle, the wideband is pegged at 22.4 A/F ratio. Should the car run super lean at idle? At cruising speeds the car doesn't studder anymore but it seems to hang the rpms at speed for a while before it decides to drop the rpms. Too rich now? When lightly accelerating the A/F goes between 13.x-15.x. At WOT the A/F goes down to 10.9 which also seems good.
