Failure turned into genius!!

Alright so I have a 1986 Chevy sprint. I have been widdling away at trying to get 50mpg during the winter.
List of mods first.
Msd 6a ignition box
Msd coil
Msd 8mm wires
Lowered car 2"
Partially blocked upper grill
Fully blocked lower grill
Wiper arms removed
Headlight buckets covered with lexan
Fresh air vents covered.


I tryed a hot air intake and it killed my mileage even with some p&g. 32mpg
So I ditched that idea. Lol
Next was my ram air intake. Hooked it all up and it worked good. But it had a problem. Over 40mph if I put it in neutral the car would die so I couldn't p&g. Because I don't want to over use the starter or ignition. So what was happening was i run a lean condition and with all that air being forced in just pushes it super lean and kills the car.So I drove it without any p&g in 50 deg weather and got 46mpg. Not bad at all. But still no p&g. So I happen to have a time when I was coming up to stop and the car died and I didn't realize it. I let out the clutch and it fired back up. Ive done this many times on various cars but it didn't hit me til just now. Lol. So now I have the ultimate p&g machine. I have a Prius basically!! Lol I've done it at 70mph and still starts up just fine after it dies. So hopefully I will be putting down some great numbers now!! Something I thought was really bad has now turned out great. Just wanted to share.
