23 mpg to 13mpg
Can't seem to figure this one out. Usualy I get around 230 mpg but after washing my engine bay (trying to keep the car wash cleaner off all electrical stuff) now I get horrible gas milage. I just read the codes and it is the same codes it was throwing before. Catalyst, secondary air injection malfunction. It is due for an oil change it has been 3k miles since I bought it. Any ideas. I thought I might have messed up my maf but no code for it. Any help would be great

Join the club, I've been getting about 100miles per tank for about a yr. Been told I need to change the headers bc of an exhaust leak, needless to say, I ordered the headers on april 29, and after a few issues, still waiting on them . WTF
Goodluck

LT1 gas gauges were guesstimate gauges. Freeway/city mix I would fill up at 1/4 tank mark, mine would get about 200-215 miles off 12.5 gallons. So imagine off 15 gallons I would be some where near 250, that was with a 3200 Vigi torque converter. Good times, I miss daily driving it.

hit 26 mpg on my way to Houston a couple weeks ago cruising from 90 to 110mph. Only got 18 on the way back cruising @ 70-75mph. That will change once I get a new rear end with 4.10's though.

the motor wasn't really hot when I washed it and I kept it off the block and hand washed it later when it was cool. I'm stumped. I'll give it a tune up this weekend and see if it helps.
