Hi Eric!
My reliable POS is a ’90 Honda Prelude SI 2.1, 105k on the odo. Other than rust, it’s actually not a POS, and until now (luckily) I have not had a check engine light.
I am getting a Code 43 “Fuel Delivery System” and just about every forum I’ve read elsewhere, everyone has their own differing opinions on what it could be, and just leaves me even more confused. Car runs just fine like there’s nothing wrong at all. Tried d/c the battery to clear the computer, no effect. The only work I’ve recently done is a new flex pipe and did not mess with the 02 sensor at all. Whatcha think?
Last but certainly not least, I’ve been watching you since the beginning. I bought this car because of you. It was a 10 year unloved garage-sitter, and you helped me rediscover my love for wrenching on cars and getting this old Honda running like new. So from the bottom of my heart, I thank you! -Ryan S
