The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.
The answer is: Throttle valve for 3/4 HP Briggs. Popular for bicycle bolt-on use in it's day. The square filed away area was rounded and more obstructive. This old school throttle body porting took it from 3/4 HP to over 1 HP. Wheeeee!
So I was scanning a friend's car today. Stock 02 GT has codes for system rich bank 1, evap leak small. Something definitely isn't right lol. I wanted to compare it too mine but this isn't gonna work lol.
He has a new FPR but you can still smell a little gas pulling the line off. Had a dorman MAF. He's coming back Thursday so I can help him try to fix it. I'm thinking the MAF or 02 sensor is messed up after looking at what they are reading. DHP didn't record some of my logs so idk if these are skewed at all.
Look at the MAF, dropping in Hz as the RPMs go up plus those LTFTS lol? N/a cars don't run that rich it seems. Mine mostly stays between 850-900mV. Should be fun to diagnose
