H series 99 hatch need help!
Hey everyone I'm new here, for starters, I bought this car as a road race project and then life happened and now it's my daily. First issue I had, blew the balance shaft, replaced it with the timing belt and water pump as well. The day I got it running again I got some bad gas.... Plugged the filter, so my dad and I changed it and dumped some fuel system cleaner in it. Then the screw that holds the rotor inside the cap came out, replaced all that mess. Well the car runs decent above 4k rpm, I'm guessing only because vtech is engaged. But under 4k it runs like crap, luggs and pings and has no power or throttle response. Any advice out there? And again, I opoligize on the specifics, I'm new lol
