Hi,
I have 96 Toyota Camry with 209,000 Miles
Symptoms with my car rough idle.
at dead stop in D (drive), the car powering steering is vibrating. only vibrating when the car at dead stop or stop at red light intersection in D (drive) lights. But when I accelerate, the car run fine.
it does only in D (drive) not in R (reverse) or in Park (P) or Neutral(N).
I have changed FRONT MOUNTS, REAR MOUNTS, DOG BONE, DISTRUTOR WIRES, DISTRUBUTOR- CAPS, ROTORS, STILL DID NOT FIX MY ROUGH IDLE.
This time, I bought used EGR Valve Control Valve from junkyard. I changed out my EGR Valve Control Valve on my 96 Toyota Camry LE.
I tell you, it make big improvement on rough idle. now, if I sat at dead stop intersection light. rough idle powering steering vibrating went away. it has 93% improvement after I changed that out.
Before I did this, I also verify if I do have an intake leaks or not... I did not have an intake leaks, so I changed out my EGR Valve Control Valve.
Watch this video clip below link to find if you do have an intake vacuum leaks before you decide to change out your EGR Valve Control Valve.
I know a lot of you are having this crazy rough idle issues after you done everything but still did not fix your rough idle issues. Report back if it helps you
