Remove all the plugs from the engine if you have compress air, dry out each cylinder, put new plugs back into the engine. If you have starting fluid, give it a shot after the MAF, not before or else you have a chance of ruining the MAF. Give it a crank and let her rip.

Thanks for the quick response. Any idea why this would happen out of the blue though? The car was on the lift for almost 2 weeks as I was working on the transmission. Anything not connected properly (O2 sensors perhaps?) after the transmission install could cause this?

Check the plugs for gasoline. You might have an injector that is stuck open. The engine might have hydro locked depending on how much gasoline is in the cylinder. If you have a compression gauge now will be a good time to do a compression test. If the cylinder(s) was filled with gasoline now will be a good time to do an oil change.

As Forrest Gump would say "Shit Happens".

Classification resistor still good? Not positive that it would cause your issue but when mine was out everything was wonky as hell.

It started today but sounded horrible so I turned it off. Left side of the engine (1-2-3-4 cylinders) all had misfire errors. I was tired of messing with it so I left it with the mechanic. I am suspecting a camshaft sensor problem or something right now..

Thanks for all the responses..

Did you remove the plugs vent the cylinders and install new plugs back in? A flooded engine will give you misfires. If you had let it run it might have cleared up.

If it started today, and you didn't do anything, the cylinders that were flooded may have had enough time for the fuel to evaporate.

Yes, but once again, the engine did not sound healthy at all. I believe the flooding is happening because something is not working and when it takes too long to start. Would this have anything to do with the rebuilt transmission? Or some oil spill as I was putting in new oil? Someone told me, as I was putting the flywheel bolts on, in the process of turning the crankshaft, I may have done something to the timing chain. But, wouldn't that cause the full engine to fail, not only one side?

I am just hoping it is an easy fix so I can go back and check if the transmission works better now..

Cheers,

After some research last night, every symptom the car has points out to the crankshaft sensor (located on the transmission itself) including rough / no start, sounds like timing is off and the shifter gets stuck in one gear. The car will be at mechanic until tuesday. I wish I could get to it and replace the darn thing to see what happens..

Final Update - It's FIXED!

I was able to find a used pump stator assembly as well as a new shift solenoid and put the trans back in for the 4th and final time.

I have over 25 miles of test drives with varied driving including some WOT downshifts and no more codes or fail safe to report. All shifting is smooth and quick but I do occasionally get a somewhat harsh 1-2 upshift and downshift (I'm not really worried about this).

Thanks again to RRphil and everyone else who contributed to this thread!

This is an awesome community of DIYers and with all the information available I had the courage to take on this project and eventually succeeded
