I have a 90 Chevy C1500 5.7L TBI
When I start the truck it idles up and has a vibration in the motor. When its in drive with the brake held it idles normal but with a slight vibration. I replaced the cap, rotor, plugs (gap set to .035), wires, fuel pump, cleaned the IAC and reset it, sprayed carb cleaner all around the vacuum lines and TBI base, checked the egr, all to no avail.
Any help will be appreciated
Thanks,
