Timing problem...
I went to check the timing on my car today. Hooked up the timing light and turned on car. The reading was at 10 degrees. This is BEFORE i disconnected the EST wire. With the wire disconnected the reading stayed the same. I swear last time I checked my timing it was in the low 20 degrees before unhooking the wire. What did i miss here?

Plugs are new, injectors are new, fpr is new, like I said, timing is not changing even when the wire is disconnected.

My Cat broke up & blocked my MUFFLER AT THE ENTERANCE. IT travelled down the intermediate pipe to the muffler neck in beginning. I replaced muffler. Still not replaced the Cat, yet.
How was this discovered?
Replaced muffler & there was the Cat Convertor. All of it blocking muffler flow! ONLY WAY THIS WAS KNOWN WAS TO DROP MUFFLER.
HOPE THIS IS A CLUE!
Yes, I did regain good amount of pep after this mission!

Have you checked how much slack in timing chain?
17mm socket on crank bolt, pop off distb. cap, move the crank (using breaker bar) and see how much balancer movement necessary to move the rotor.
Beyond that you do have an old engine and it could be that time.
What are the running temps?
If consistantly high, it could be that time.
