so i have a 95 civic coupe that last year i had a ZC Vtec Turbo in. i spun bearings last year and decide to put a b18b in this year. i got a b18b that was obd2. so i put it in and wired the distributor and fuel rail to the obd2 parts. i unwired my resistor box since im using stock injectors for now, i figured i'd run it with no turbo for a couple weeks, get all the bugs out of the new engine.so im running it on a obd1 computer. i start it up and it bearly runs, it stalls out and wont take any throttle. i checked the timing on the engine, all the marks line up. it will only bearly run with the distrbutor all the way back. i tried switching the map and tps sensor connectors around thinking i mixed them up but no difference no matter witch way i put them. i;m no sure what to do, bad computer/distrbutor/sensor???
 
as i said i tried switching the sensor connection on the throttle body but it didn't make a difference either way it ran the same. and i only have the one for idle control on the intake, the iat is in the intake tube on the new engine not the intake manifold
 
so i changed back to an obd1 distrbutor and all is well, look through the forms i found 2 different wiring diagrams for running an obd2 distrbutor on obd1 wiring, apparently the one i used was wrong, it had my tdc sensor and cylinder postion criss-crossed. owell all is well now
