Hey ht for starters I have a 00 civic with a b18b swap. It was running fine for about 3 weeks. Then the other day it sounded like it was choking when I pressed the gas. I can press the pedal lightly and it will run fine but when I push it a little harder it sounds like it wants to choke and keeps bogging. Also my speedometer gauge is now jumping up and down when driving any help would be great Thank you
