Great news!

Thanks for the updated information Abe Scott Very useful for anyone else suffering with this issue in the future

Update: I think I have got it after all the work, time, and money spent. I started checking again I found an unbelievable vacuum leak around lower intake manifold. replace gasket today runs great thanks for all of the support. something that simple fix. when the engine was swap the starter was replaced. The gasket moved or something apparently cause a vacuum leak. I had no idea a vacuum leak could cause random misfires. I was sure it was an ignition problem.

Broken body to motor ground. All good now.

A long time ago my company issued me a Chevy S10 that had 6,000 miles on it. It used 2-3 quarts in a 3 hour journey when driving on the interstate due to rings not seating properly. I needed that truck to get to and from my home each weekend. I bought the cheapest 10w50 high mileage oil Wal Mart sold at the time by the case. After a few weeks it used less and less oil. I did not change the oil or filter for 50,000 miles. At around 45,000 it had stopped using any oil. At 125,000 miles it ran like new and did not burn a drop of oil. I would never reccomend anybody ever do that but my point is the Toyota made engine is probably fine. But if you choose to buy it use a synthetic blend of high mileage oil, not pure synthetic. The high mileage oil has additives that help prevent worn out piston rings and valve seals from leaking. Me, personally I'd pass on that one. Bottom line here; if homey didn't even change the engine oil, he probably didn't maintain brakes, change coolant, and certainly not the timing belt. Last thing you want is a great looking car all broken down in your driveway. To add: the reason oil manufacturers reccomend mileage or time intervals is not to sell more oil. The interval is reccomended due to condensation building up in the crank case from heating and cooling. If dude drove it 5 days a week that would mean a heating and cooling engine at least twice each day. Many do not realize this but you can check the oil filler cap for a milky substance. If that is present the crank case has had water in it for a while. Smell the dipstick for gasoline smell to determine if that has damaged piston rings and intake valves. Done.
