Rough Cold Start Up. Runs Fine Once Warm.
 
Lately have been having issues when starting my car on a cold start up. I will turn over the car somewhere around 3-5 times while holding the gas down a bit. Once on, the car will have a rough idle to the point of stalling and it has stalled if the gas isn't held down. When driving it will lack acceleration and blowing out smoke until it warms up where it runs like it didn't even happen.

The car uses somewhere around 5 quarts of oil every 2 weeks, rings are just jacked up. I have cleaned the MAF, IACV, and the EGR valve. Replaced the spark plugs with cables. Just today something came to mind if it could possibly be one of the coolant temp sensors that's causing the problem?

and you're asking us what we think is the problem?

check the taillights, that's probably it

I'm well aware of the issue of it using 5 quarts nearly every 2 weeks. I'm broke right now to even go ahead & get a swap for it. I'm trying to just keep it running long enough until I can get an engine from who knows where. I wasn't having any issues with starting the car a couple weeks back.
