i have a 99 ls1 6 speed swaped into a fd rx7. ever since the swap was finished i have had a problem with the idel. sometimes i would crank the car and it would b fine and then the next time the rpms may go as high as 3k rpm. i have made shure it is not a vacume leak and i have replace the sensor meany times. eventualy i just set it by hand to idel around 800 rpm and never pluged it back up. i took it to get tuned last week and my tuner was not able to get the solenoin to responed to his pc command . my question is is there any voltage measurement i should b able to see at the plug? i realy need to get this figured out as it is kind of embarasing having to hold the gas a lil untill it warms up.
