Jittery rpms on freeway with AC - 06/19/07 01:13 PM
Hello, new here, I was told the rpm will jump some when the compressor kicks on, but while on a 4 hour trip my tach jumped up about 500rpm,then down, up , down , up, at least 6 times in about 15 seconds. It did this a few times during the trip. Something to worry about? Only 24000 miles on my 03 GT.
I had a 96 cavalier Z24 that did this and a few months later the dealer said the tranny was terminally ill and each time it did the jump they heards a "grind" in the trans. They coudln't say what it was without taking apart. That car wasn't worth fixing at 200k on it.
