i hope some one out there can help me if not i am quitting the game and buying a truck. I have a 93 honda civic with a b16 motor. I have bisimoto header, skunk2 stage one cams, aem short intake, and apex exhaust, rc310 injectors, and s100 hondata. my problems misfire when vtec engage, run very rich, idles at 2000 rpm and on take off its feels like its bucking. this is what i have tried new distributor, change map o2 tps coolant temp. sensor, had the whole engine harness remove and had all wires soldier together that was twisted or broken, and had the chip removed. Still have the same problems runs even worse and now i got six engine codes 1, 3, 7, 14, 21, 22. i will not put the shop on blast but if they cant fix it on friday i will. so help

Why would you even try to crack VTEC with all of thoses codes?

If you reset the ECU, do all of those codes return? Is the MAP sensor on the throttle body attached to a connector? Are some sensor connectors swapped?

they sure do

the map sensor on the throttle body

What ECU do you have? Are the MAP sensor, TPS, IACV, and VTEC solenoid/pressure switch properly pinned to the ECU? Do you have a multimeter to check the wires?

check/replace the basics. timing, spark plugs, spark plug wires, firing order, etc...i would try a stock working ecu. also, make sure the plugs are plugged in the right sensors. people confuse the tps and map sensors alot cuz they both have three pin plugs. iacv only has two.

Ron asked you a bunch of question that you have yet to answer.

yea theres a lot of things going on here. Definatlly an electrical issue, must not have something wired right, or pluged in correctlly. Its all been said above, personally id just get a new harness. One from a EJ1 D16z6 engine. Already wired for vtec that way you only have to wire the body to run VTEC.
