Hello all.  My 1991 Honda Accord wagon EX shudders when you start from a stop in first gear.  It is really bad when starting from a stop going uphill.  I had the clutch/flywheel replaced a few years ago and this problem was present before and after that.  I actually think the problem was not a warped flywheel in the first place, but some other system malfunctioning.  

 

  What might cause a similar symptom to a warped flywheel?  I have tried a couple of things to fix the issue, but nothing lasts more than 5 minutes.  I replaced the air filter that was extremely dirty, and the car drove perfectly smooth for 5 minutes, then back to its present condition.  I also noticed when I cleaned the EGR passages, that it did the same thing, drove awesome for 5 minutes, then back to shuddering.  This makes me think the problem is something with the air/fuel delivery that needs to be adjusted/replaced.

 

  Any help would be awesome.  The car has 250k miles on it and I am planning to gift it to my nephew who is turning 16 in a couple of months.  Thanks in advance.  T

Honda troubleshooting guides point to the EGR valve. Also check the fuel filter. hondapartsnetwork.com has some of the best prices for these OEM parts
