'92 22RE Strange Intake Noise
Video with air cleaner box open so you can hear. Been doing this for a month. 15% loss on all rpms. New plugs, cap, rotor
Check engine light flash shows no codes, Valve lash is in spec. New engnbldr.com head 2 years ago. Catalytic converter removed years ago. Carb cleaner test done on all intake. Airflow Sensor turns easily, not dragging. Could it be a potato stuck in my exhaust ? Video; Air delivery is stock (no cracks) Valves, chain & guides are 2 years old and inspected with lash check New chain tensioner hasn't been touched in 2 years - it's been running fine |
Is your air intake system stock?
Have you checked the air boot to the throttle body for cracks? :safari: |
Doesn't sound good at all. Lots of high frequency noises, metal on metal type. Oh boy.
Take off all accessories Probably a valve? |
Engine sounds like it is misfiring to me. The cause I don't know.
|
Op has enough info in the op, but I got nothing.
Need more information please Maybe a vid standing in front of the truck, reving it at the throttle body? Test all sensors. A quick roger brown google search will get you there. Recheck timing. |
I'll throw out chain tensioner. Did you replace?
The proper torque for it is something very low like "tighten by hand / loctite". If it's too tight it gets stuck in the open position. Is that the chain I hear? |
