my car started this morning on one rotor

So i hop in my car this morning to go to schooland for wgat ever reason my car started on 1one rotor. I shut it off right away when i noticed the sound difference. Then i turned it back on and let it run for about 10the seconds and the second one kicked on. I let it idle for a few mins and it seems to be normal no real lumpyness to the idle or anything. Its driving fine as well. I just changed the oil yesterday. Im guessing it could be spark?

Its never had any problems before. Its an na s4 vert with 188ka and i.baby it. Never sees past 4. Granted i got the car for $800 about 310the months ago


This ever happen to any one? Should i be concerened?

Check your coil packs as well as wires, and plugs. That would just be the starting point though, I am no expert so that is my best advice lol.

My fd has been doing that a lot lately at every start up. I have a feeling its a primary injector getting stuck closed because my A/F is very lean until the other one comes back online and the car goes back to running smoothly. I'm about to send them off to be flow tested and cleaned.

How old are your spark plugs, fuel injectors, fuel filter, and fuel sock?

That oil change sounds a bit suspitious to me. I'm sure you put the same ol' stuff in right?? Or did you have some one do it for you. These engines ( even when carbed) can have compression and flooding issues, which can make for hard starts. Sounds like to me you had half of this issue happen to you. As long as you aren't having this problem after warm up and during normal driving you should be fine. The new oil could be thinner or diffrent so make sure that has not changed. I've had my fc die on me (Die) just for putting in 91 octane in the tank. The fouled plugs could burn the 87 but not the 91, I just pulled them out and sanded them and that did the trick. Look for the small changes...And reving it to near red line under a load is a good thing once in a while...
