went and got a spark plug non-fouler and spent a while drilling and grinding it out. got 2 of them in one pack from o'reilly auto parts for 3.99. made a good fit for the o2 sensor. installed it.
made 4 more plates today too. installed them. mixed 1/2 tablespoon of sodium hydroxide with water. started out @ 5 amp draw cold. sealed booster. checked for leaks. filled gas tank at a late night station. drove a total of 32.9 miles round trip on the interstate right back to the same pump i used before. topped to brim just like before and it only took .6 gals. that's 54.8 mpg!!!!! YAY! up from 38 mpg with no mods. i have no idea what percentage this is. i'm guessing close to 40%.
now, what about the IAT, MAP, and other mods? i wonder.
thanks for the help and encouragement y'all. it's much appreciated!
i still have somewhat of a bubbler problem but, to just know this works and i'm over a big hump is great!!!
