I've got a SiR2 motor swap in a Civic 92 with chipped p28 ecu and a year ago it broke down on me and i kept it sitting for about a year and drove my TL instead and just recently i had it towed to the mechanic and he replaced the timing belt and spark plugs and told me that he couldn't figure out why it wasn't running right. I got the car back and it runs like shit! if i am at a stop and go to hit the gas the motor bogs and studders really bad. I actually have to keep the pedal down and wait 3-5 seconds before the motor's rpms start climing. and when i finally start going it does pretty much the same thing. I'll push on the gas and the motor takes forever to respond and the rpms climb slower than shit. one thing that the mechanic said he thinks it might be was something to do with the fuel line or pump. When we pull the vacuum hose off the fuel regulator the idle seems to get better but the motor is still slow to rev. I really want to fix whatever it is, the car was bad ass before this shit happend. Any help would be awesome.
