ls/vtec misfire lost need help
Well here is the story I bought a built b16 head from a friend never used after build machine shop said it was good. Put the head on new timing belt head gasket, spark plugs, wires, cam seals, etc.
1. started the car ran fine idle was great sounded better then it ever did before.
2. Took the car for a ride drove it about 15 miles came back.
3. put gas and fuel cleaner
4.drove around for like 30 mins did a quick burn out afterwards car stalled drove it back check timing still stalling after idling for a second. Drove it home and its missfiring like crazy idles really low and stalls most of the time.
4.Changed spark plugs again, dizzy cap and rotor, changed dizzy completely, changed injectors & clips, tps, map, iacv, ECU, o2 sen, Fuelpresreg and fuel pump.....thought the gas might have been bad drove it until it was getting empty put 1 1/2 gal of 110 and filled the rest of the tank with 93, compression test came out 150 150 145 150 not that much of a loss only in 1 cyl, timing is perfect
After all of this the car is still mssing and idling like ish, I'm lost guys can you please help me the only thing I can think of is something in the wire harness got cooked and i should change the harness. I changed everything that could cause it except the harness even changed things that could not cause it because I needed to keep my mind and hands busy.

your compression isn't very good IMO. my b18a stock..160,000 miles has 190 in every cylinder. having vtec should make it more... I'd say check your valve lash. when i first got my car running, it ran for ****, i got new plug wires and it suddenly ran great. just something to check also..
