hello, I needed to know what is normal compression for a d16a6 si? I checked my comp and its [FONT=&quot]110-75-150-112. Is that normal. I think this is why my car stalled and now wont start. I have spark, fuel, and air.

no thats definitely not normal. it's actually quite terrible. mininum psi spec for an a6 is 135psi and nominal is 185 psi, with a max variation between cylinders of 28 psi. so basically your engine's rings are fried.
 
Try a wet compression test. Remove the spark plugs, pour a little ATF down each hole. Hook up a battery charger. Open the throttle wide open. Crank and see what you read. I have seen many hondas lose there ring seal from sitting around too long. Also check your cam timing, If you jumped a few teeth you could have all kinds of screwed compression readings. Can you provide a little more information on what happened when it died?
