Let's start diagnosing it ourselves. See if there is an Autozone or the like that will scan it for all (hard AND soft) codes stored in the computer's memory. Remind them when they say "But the Check Engine Light isn't on!" That SOFT codes will not set the CEL. Also remind them that pulling soft codes takes a little more effort than hard codes.
Next, find a place like the one above that either loans tools free (with deposit) or rents them cheaply and has a fuel pressure gauge they rent or loan. Check the fuel pressure and note the reading.
At the same place, look into buying or borrowing or renting a timing light. Check the timing. We've got instructions (www.2carpros. Com/articles/set-engine-ignition-timing) and let me know what you get.
Black soot is unburned fuel. Oil is blue smoke.
Can you scan and upload the receipts for what was done at the two locations? If so, upload the scanned files to a file sharing site and send me the link(s) please. You said one place said the distributor cap needed replacing and they did that, then the other place said the distributor needed to be replaced. While related, they are completely different. The "tech" at the second place should have noted WHY the distributor was specified.
