A1 Cardone Remanufactured Mass Air Flow Sensors precisely measure the amount of air flowing into the engine. They provide exact information used by the engine to calculate fuel delivery. These mass air flow sensors will not cause hesitation or stalling.
"From what I read in some research, this sensor (variable slide resistor) is able to provide more position points of the intake flap than the stock, sending a more linear signal than the stock sensor. I was trouble shooting my rough idle, thinking this was one of the the faulty components, but it turned out to be the engine temp sensor. So, I swapped the old with the new, and there was a difference in throttle response. I took apart my old one, and didn't find any wear-through on the circuit board, but still tweaked the prongs so they went along some fresh copper, and still, the NEW sensor was a major improvement. BOTTOM LINE, provides more info to the FI system for better response and overall performance. A worthwhile "upgrade"."posted by: Farfegnugen! on April 11, 2009
