Vibration Okay guys, I have a 97 z28, 108,xxx miles, automatic. I’ll get around to making a sig one of these days but until then, here are the mods. CAI, edelbrock throttle body and headers, deleted cats, flowmaster muffler, 3600 vigilante stall, 3.73 gears, 17 inch american racing 200s rims.
First off, the car runs like a freakin champ, no power issues or anything like that, but I have a vibration and no idea what it could be. If I have the car in park and hold it at around 2-3k rpms it vibrates, steering wheel vibrates, everything vibrates. If I’m driving the car, there is no vibration until I hit about 50 or higher, and it also gets a lot worse when I let off the gas. Now the tranny has a leak coming from up behind the converter. I also have code 1351(ICM voltage I believe) no starting issues, and 141, 161 pending but I believe those are there because I have O2 sims. There is also a slight tick/squeak that sounds like its coming from the harmonic balancer. It doesn’t make the noise all the time nor is it a continuous sound. It is the loudest after getting on it pretty good and then putting the car in park, I’ll try to see if I can get a quality sound clip of it. I took the belt off and all pulleys are normal, no play or anything. But anyways has anyone had this problem or know what is could be? Thanks in advance. -Kyle
