Ok I bought some one elses project and now im paying for it. Ok the car is a 91 CRX hf with a d16z6 swap. The car runs just as im stating. It starts up great, the idiol surges around 1500-2000rpm. When you rev it up it spudders from 2000-4000ish, than opens up past 4200 like nothing is wrong. It has the xenocron obd1 jumper, 4 wire o2 sen. I read all the internet instructions for this harness double checked map sensor and all that stuff. I also did a tune up, cap, rotor, wires, plugs. Still same thing. I also know my Vtec pressure switch had low resistance when I checked it compared to my buddys d15. I didn't think that would effect the low rpm problem. Im kinda new to hondas and lost at this point any other help would be great
