P0300 Code. Rough idle in R and D

Just replaced power steering pump, everything seemed to go well. Some Dexron spilled while filling up the PS pump reservoir. Engine struggled to start, had to crank it twice for the truck to stay on. Air box was removed and unplugged when I started the truck. Maybe that’s why it initially had trouble starting it. Plugged it back it and taco started fine. While backing up the truck idles pretty bad and is kind of jumpy, acts the same in Drive. CEL came on. P0300, P0301 P0302. Any help would be appreciated.

 

the codes you listed are spark/misfire codes. Check if your wires are seated properly. Did it just start running weird or was it running rough before the CEL? May have a couple bad coil packs or the ecu is relearning since you had something unplugged.

 

Thanks. It ended up being bad spark plug wires. Replaced, truck runs great now.
