Vibration on 1990 Vortec 5.7
1990 Suburban
O.K... here's what I have replaced.
On the 23rd of last month, had new computer put in... This week...TPS...EGR Solenoid...cap,rotor,wires,and plugs...injectors. Cleaned out idol air motor, fresh oil change.
Checked ALL bolts from front to back and all are tight.
Replaced fan clutch last night(other was bad and THOUGHT that was source of vibration).
Took it(truck) out and it STILL has a vibration like a window fan out of balance.
NOT a steady vibration...intermittent.
I am ready to send this thing to the junkyard!
