I am looking for some thoughts or advice on what action to take on my turbo'ed E85 car. Car has been built and running solid for years, so this is not a setup that was just installed.
Short background:
- car sat for awhile during the rebuild of my transmission
- put back together and had a random misfire with P0300
- performed regular maintenance (plugs, checked for vac leaks....) everything appeared OK
- sits for another couple months while busy with other things
- now it is no longer giving a P0300 code but now it is a P0203 and P0303 code.
Questions:
- Is P0203 a code that relates to a stuck injector or a faulty connection/wiring? Never had this code before.
- Could the fuel condition play a part in this? Car was on about 1/8 tank older E85. Is there any additive that can be used with fresh E85 to help clean injectors?
