finally back, been out of town for a while. thanks for the info big jim. i'll do this test over the weekend. but in the mean time ive put some mystery oil injector cleaner in the gas tank. the reason because a machaninc was telling me that he had to replace one injector every year for some reason on his own car. He was on his fourth injector when he decided to try the mystery oil...he hasn't had to change one since. he only adds it to the fuel about once a year. so i figured it couldnt hurt. but like i said i will still check the map sensor.
