how is the coil???

rdmypny

that was my next step i just thought if it were the coil it would do it all the time. but i don't know

nope, your coil will produce spark under smaller rpm's but will cut out as it gains rpm's. so will your egr, iac, and the mass air sensor. or at least thats what ive been told.

rdmypny

i know the mass air is ok i checked and cleaned it. what is egr and iac?

Did you have the problem before you installed the new parts?

rdmypny

yea and it gotten better everytime. but not all there yet

egr is exhaust gas recirculation valve, if it were partially open it'd cause a miss at idle and under acceleration be okay.
