Ok, been trying to eliminate this 2k annoying vibration for a while and have done a whole bunch of things with new parts. I guess I would leave the tech side for a while and hop over here for a vent.
The other day my son asked about the problem. He saw I been working on it for quite some time and remain unresolved. He said "Maybe the car is old". I know it, 32 years and 322k miles. I was still hopeful that I will eventually zero into the problem but now still in a puzzle. Few times I thought I got it fixed but turned out to be no. I have a few months before the wife would pressure me to do one way or another. By that time, there will be one car in excess in the family so wife thinks the old Accord should go.
I am up to a point that I'm weighting between continue troubleshooting/keeping or pick a stopping point. Very frustrated with not able to find the cause of the problem. Swapping another A20A3 is out of the question so pretty much have little options for now.
I am not sure but I may ended up give it away to a member here. I cannot comprehend it going to a junk yard.
Sometimes I see an adv for a car that the seller says "many new parts recently installed" and wondering if it actually means "I have tried swapping many parts to solve a problem to no avail".
