Hello, I'm sure this has been discussed before. I have a 98 Silverado, 5.0 vortec.
I have a cough/shutter when under a load, like passing on the freeway. I have noticed its between about 70-78 MPH, or around 2000 RPM, also it does not do it untill after it warms up. Other than that, she runs great! Can barely even feel her running at a light.
But this has been haunting me for a while now. I pretty much have changed out every sensor under the hood, egr valve,, plugs, wires, cap, rotor, distributor, fuel pump, spider injection, coil, ICM, and still can't find it. Even had a dealership look at it to no avail. Any help is greatly appreciated!
