Hello! I guess I haven't ever posted on here, so I'm not sure this is in the right place, but I've experienced an MPG drop down to an average of 28-34 mpg, consistently. I've also noticed power loss on the lower end, and even VTEC just isn't what it used to be — even in this car.
I have a D15B (rare VTEC-E variant), and suspect a bad MAP, though I'm getting no codes.
Any ideas? EGR was replaced just a couple of years ago and car is maintained with fully synthetic oil, DOT3, etc. Replaced O2 sensor & fuel pump already.
Trying to take a road trip this weekend for my birthday, and I'd rather get the record 63-68.9 MPG I got pure highway a few years back.
Thanks for any help!
P.S. My brother actually found my VX on this forum back in 2011.
