Car throwing codes. Need advice
Coming home from Bowling Green on the interstate and the car started misfiring and jerking. I thought that from the way it was shaking I might have a flat, but it didn't. The check engine light came on. It was blowing out white smoke from the middle two exhaust pipes. I had just filled it up with Exxon, so I thought it might be bad gas. When I got home, I filled it up with Sunoco (my usual gas) and added a bottle of octane boost. The check engine light went out. Today, my buddy put it on the computer and these two codes came up
200 Low voltage to the fuel injector
300 Engine misfire detected.
Anybody ever have this happen to them and what was the fix?
HELP PLEASE

I had the P0300 code throw on my Z a couple of weeks ago. It was the only code that came on. Pulled the plugs and wires and replaced them. #8 plug was damp when I pulled it. It wasn't firing at all. Someone changed the plugs before I bought it last year and put in Denso plugs. I put Delcos back in. While removing the wires, 3 fell apart (again, I am sure whoever did the plug change was very hard on the wires). I don't know if this will solve your code. There is a whole list of things that could be going on with the P0300 code. I just took a shot at the tune-up, as when I did a search for that code, that is what a lot of other members did to solve the issue.
Good luck!!

I think there is a service notice about the the wires to fuel injectors being chaffed. Check for chaffing/or bad connection to fuel injectors.
Also, with the heat, there have been a lot of battery failures lately. Replaced my leaking crappy Delco battery last week. Check for good terminal connections. Might try taking the battery out and have it load tested at your local auto parts store. Optima red top battery is the one of the better batteries.
