Hey everyone, I have a 97 tbird 4.6L 108,500 miles. Every so often I’ll get this weird idle where the rpm needle will go up and down while the car is parked. I’ve replaced the idle air control valve along with the gasket not too long ago so I’m confident that’s not the issue. Maybe the throttle position sensor? Sometimes it’ll fluctuate very minimal and other times it’ll fluctuate a couple hundred rpm’s. I don’t know if I’m able to post videos in the thread but I have a video of what it’s doing although it’s pretty self explanatory to imagine what the issue is. Again, this problem doesn’t occur every time I start the car. Only every so often. Thanks in advance!
