For those that don't know, I had to replace my old 90K mile engine for a new 20K mile engine in my 98 camaro. Long story short, lost oil while driving and burned up and spun the bearings.
New engine is in and everything is hooked up and running. Only took a few seconds of cranking the engine for it to fire up. I instantly heard the sound of a misfire and sure enough a SES light came on. Code came up PO300 which is a random misfire error. I checked all the plugs, wires and coils which all seemed ok and in the right locations. I'm thinking it might be the injectors but i'm not sure if the inj would cause an error like that. The coils have less then 10K miles on them as do the plugs and wires. God knows how long the engine has sat in a warehouse and the injectors are just about the only thing I did not move over from my old engine. Something happened that makes me think it might not be them. While testing the coils I removed the plugs from the center coil and the engine ran smoothly. If it was the inj it would still have ran rough right? After a week of doing the whole swap myself my brain is not working as it should. Might be from sniffing all that oil/gas/coolent/tranny fluid and I don't think banging my head an every piece on the car helped either. thanks for any help you can give.
