MAF Sensor S70

I just replaced the module on mine this weekend. I had the same code from the AutoZone reader. Symptoms on my car were: CEL that would eventually disappear after approx 100 miles then re-appear again, slight decrease in mpg, idle would fluctuate and sometimes stall, I could sometimes feel the engine “hiccup” while at cruising speed. I performed an ignition system tune-up when the symptoms first appeared to rule out that possibility. So far the engine runs and idles much better, too early to see any change in mileage. To remove the unit, others have recommended using a heat gun or hair drier to soften the hose, I just did it with just a hot engine and wore mechanic's gloves.

Good luck,
Alfredo
