Picked up some CRC Mass Air Flow cleaner and was going to hit my 94 SR Mass Air Flow sensor as I am pretty sure in the 200k clocked miles it has never been cleaned. Have noticed a slight uneven idle which got me to replace the Idle Control modular which maybe did nothing. I unplugged the MAF and idle was super smooth. So figured a cleaning and would be a done deal. Well reading the back CRC label it aays do not use on Karman-Vortex air flow - Toyota Supra Turbo, Mitsubishi's and most Lexus vehicles. Now I don'tbelieve the 94 SR has a MAF made by Karman-Vortex but thought I would check if anyone has 1st hand experience before I clean with CRC.
