High Speed Miss
I have an 86' with 302 and AOD. I just did a rebuild and it runs great except for a high speed miss when under load and an occassional miss at idle.
I have installed new plugs, wires, dist cap, rotor and coil. Problem still present.
I did not replace the injectors during the rebuild. Might they be the problem?
Any assistance appreciated.

you did install a new timing chain right. pull codes , replace fuel filter. what kinda plugs did you use? also make sure that #7 & 8 wires are not touching. may just have a plug wire arcing as well so pop the hood at night with the motor running.

Thanks, I used Bosch Plugs with Accel wires, cap, rotor and coil.
No codes when checked and a new timing chain was installed.
I will change the fuel filter and check to make sure nos. 7 & 8 are not touching.
Much appreciated.
