hey whats up.. i have a ls vtec in my 92 civic.. i used a obd2 wire harness versus a obd1.. i have a obd2 distributer and a obd1 alternator.. but besides that my car isnt reving out all the way and the idle is irratic.. its open head and keeps misfireing out the muffler... i cant get it to rev past 2 grand but the weird thing is when i first start it sometimes is alows me to rev it out completely for a few seconds then it starts bouncing idle at 2 grand and doesnt respond to throttle.. does anyone know what it can be
