Well after playing with the 87 we have found a strange issue, we hooked the vacuum gauge up to one of the empty vacuum ports on the intake, at idle it was sitting around 20 hg but as we revved it up the vacuum raised to about 25-28 hg. Isn't it supposed to drop the higher you rev?
Also the O2 sensors readings are jumping from .025 volts to .863 volts at idle, when you rev the motor up it stays in between .247 to .638 I know that is better but isn't it supposed to be closer to .4 volts?
Thanks for your help!
