how did you set the tps

89used2roc

yes just adjusted the tps for a second time just to make sure it was right then i unpluged the ecm power wire to reset code and them took it down the road same issues and i now have a code 21 and code 43 starting to think it's the ecm or possible ground from the ecm just wonding if the car would still run with a bad ecm also does any one know off hand is there a ground from the ecm to somewhere under the dash

code 21= tps which you have already adjusted ,code 43= electronic spark control, check that ecm A-B connector terminal b-7;it should be over 6 volts unless the system is sensing detonation. check for a loose connection. replace the esc sensor and/or module. this is according to my manual,jimmy

the ground is on the pass head

put a coat of die electric grease on the terminals that connect to the computer

do you have a multimeter?
if you do just ohm test your injectors. Its quick and easy.
