car missing need help please....
my 94 sc300 started missing the other day so i changed the plugs and wires.didnt fix it. so i started looking into it a bit and found the number two injector was not firing. no big deal i change the injectors. all six with new ones. still not fixed. still has the injector not firing. so i got to reading and found the ecu caps could be bad. sent ecu off to get fixed waited forever. but got it back. plugged it in and still not fixed.ive changed everything i can think of. so what else could it be. timing is dead on i have voltage to the plugs and injector. injectors all fire. what could it be.please help. any ideas would be great. thanks.

i checked the plugs. they are all good. replaced the plugs wires and cap rotor button. all new. no burns or spark jump. the injector number two was not firing put in new injectors all 6. not sure if they r opening or not but i did check the injector plugs. they all have voltage. tps and maf are good. car runs just missing some. ive heard that if a valve sticks it could cause the same problem. which makes sense to me. has fuel has spark just no combustion in one cylinder because its open or partly open. everything is new injectors rotor cap plugs wires. only thing i can think is to do a compression check. unless anyone here has some other info. anything would help. im sure its just something im not seeing and will feel dumb when i find it. thanks for you help guys.
