I have gotten a p0203 injector circuit malfunction. I replaced the injector and plugs to # 3 cylinder. Problem was solved for 8000 miles. Just got the code again. It appears to occur only when motor is cold.

Well checked the plugs and the e3 diamond fire ceramic tip was broken on the exhaust side. Good thing the diamond tip kept the tip from falling into the cylinder. Bad news don’t trust the e3 switched them all out with only 30000. I also saw signs of heat issues on most of the other plugs.
