Parked back in my office parking lot and started investigating. CEL blink code was for MAP sensor malfunction. Got a multimeter from the office and determined that the map sensor was faulty. Has +5V power and ground, was outputting a pretty constant +5V instead of the expected 1~3V.
Once I’d determined that the problem was the MAP sensor, I decided to just gently drive home since the perceived risk of engine damage was low. But after going a few blocks I realized low RPMs were unstable and high RPMs were better, so I hopped on the interstate and made it the rest of the way.
Now I’m kicking around trying to decide if buying locally is worth it. $60 or something for OEM replacement, $20 for sleezebay clone.
