good mechanic??

[sleeperx]

whats up, new to the forum. i own a 96 s14 with and sr motor and tray swap. living in cincinnati there weren't many options as far as shops to perform the swap. unfortunately i chose zerolift!>> do not go there! ship your car out of state if you love your car! their less than poor ethics and knowledge are another convo. The car was running fine for about 3 months. now it idles rough when cold and horrible when warm( rpm drops to almost stall when u push clutch in, when at red-light rpm goes from 300 to 1400 rpm and when i try to get on it at all the motor hesitates and sputters around 4600rpm like its at top of rpm band, loses power) its running really rich i can tell too( smell it and black shit on bumper). so, i need a top notch tuner in cincinnati or anywhere in the country for that matter! please help
