Intermittent rough idle

[MyTaurus8AChevy]

We bought the MAFS cleaner tonight from Advance Auto Parts (thanks for the tip shorod ) We warmed up the engine and when we got home we disconnected the negative battery cable. We cleaned the MAFS and reinstalled. Car will sit all night and in the morning we will re-connect the battery cable and let it idle for 15 minutes. Then we'll take it on the freeway and drive it around town. I think that's all we need to do. We'll let you know if the MPG gets any better...

WOW! All I can say is that MAFS cleaner is simply amazing!

It looks like we're now getting 24-26 in the city, and a amazing 30-33 on the highway Of course for doing something like MPG it takes time to get an accurate reading, but initial reports indicate that at the very least our milage has doubled I guess I'm so surprised because we used CRC contact cleaner on the MAFS just a week or so ago, so I didn't really think is was all that dirty, but after using the MAFS cleaner it did look visually cleaner. This now confirms it. My guess is that the contact cleaner may have left a residue of some kind behind, where as the MAFS cleaner does not. All I know is that there is a noticable difference. Before, when you were at a red light the tach needle used to fluctuate a little, which I always thought was normal. But now it is ROCK steady!

I want to thank everyone in this thread for all of their help with this. I love taking care of this car. I'm not one to try to save money on anything that it needs. I only care about it running as good as possible and now it does. I whole heartedly recommend that everyone give this MAFS cleaner a try. You've got nothing to lose, and everything to gain. At around 7.00 a can it will easily pay for itself in short time
