At $438.59 I hope not! By proper diagnostic equipment do you mean a voltage meter? I need to test my ICV as well. I cleaned it with the same result as the MAF sensor. Car idled great until it warmed up to operating temp. Then the RPMs dropped to 600 with misfires. I also have a Fuel Sys 2 CL-Fault, whatever that is.
