Here is a list of what I have done so far:
- air filter
- cleaned throttle body
- new engine and transmission mounts
- new o2 sensors
- new auxilary air valve
- new cam timing solenoid
- battery and alternator tested perfect
- replaced two coils that were corroded, the rest look good
- new ac delco plugs
- new thermostat
- new pulley on tensioner (all other pullies sound fine)
- new belt
- new water pump (fan still works like normal)
- transmission fluid changed
I have no idea what it could be, it idles like its misfiring but no codes are thrown and when I let my foot off the brake it surges forward but the rpms stay steady at 625. And any rpm above 625 the truck runs great, no issues at all, it is just at idle and when rolling forwards. I also notice a tapping noise similar to when the transmission shifts but its a continuous tapping in unison with the surges. Something I have noticed is that it ran for a while with low power steering fluid and the pump makes a buzzing noise when running now. Any ideas are appreciated
