What was this?!
 
Whats up everyone? I had a little problem with my FD this morning, did a search, but I don't know if I'm searching for the right thing.

I haven't driven my car in like 5 days. I started it up yesterday just to move it in front of my house to pack parts in it because I'm heading down to Jersey to have Rich and Ihor install them. I move it back after I'm done, a total of about 20 feet of driving and no idling. I go to start it this morning and it won't start. Alright, I'm guessing it's flooded. I keep cranking it and cranking it and it finally starts, but it feels like it's on 1 rotor, and NO power at all. Lot's of backfiring. I start panicking, thinking I have a blown engine or something, as there's a lot of smoke coming out of the back as well. I let it idle for like 4 minutes like this, backfiring and running like shit. I get it and rev it to about 4k, and it makes a different sound, like power was just unleashed. I let it drop to idle, and the backfiring is gone. I rev it up, and it's normal again. But I have no boost! I HAD to take it because I am leaving straight from work today to head down. So I start to drive it, and about an 1/8 of a mile down the road, I have boost again. Why? Why didn't I have it when the car first started running right? And was I correct in the assumption that it was flooded? Does it really feel like it's on 1 rotor? It runs like it's brand new now. Thanks guys. ~A-Rod

Sounds like you flooded it pretty good. When these motors flood they lose compression. All the extra fuel burning off was most likely the cause of the smoke. We'll check it out when you get here.

Yes, you broke one of the cardinal rules of rotory driving.
Never start a cold engine in cold weather just to move the car and turn it off before it is fully warmed up.

A spark plug might have been fouled and after running a while it cleared up after the carbon was burned off. Most likely the leading plugs as they fire in series and are more likely to misfire. The trailiongs have their own coil and thus are more resistant to fouling.

Well it wasn't cold out yesterday when I started it and turned it off, I had a t-shirt on. This morning was cold.

That's interesting about the plugs, I hadn't even thought of that. So a plug can become fouled and then unfouled? I thought once they were fouled they were garbage?
