My engine light blinks constantly and when it does everything on my dashboard drops. The fuel gauge drops to E, the RPM meter drops to zero, the thermometer drops ect. Then every so often when I drive and rev the car too hard the car starts to jitter as if about to cut out. I am concerned that it may be a transmission issue or the result of the engine light. I have check with an ODB reader and have gotten a total of 12 codes and not sure where to start or what the problem even is.
Do you
have the same problem?

Even if a battery is only a year old it stil must be checked with multiple codes like I said in first reply it can still be bad. So do what my first reply said. And give us the codes as one code may effect other ones.

Your battery needs to be put on a machine not you saying it's ok. You think it's ok because the car starts but not might be. U1001 code si the ecm isnt' getting communication so for that one a pro needs to look at it. And the misfire thing you are talking about there isn't even a codes showing for it as the codes listed are not misfire codes. The 745 code can be result of poor running engine so engine codes must be fixed first. The 462 code is fule level sensor as well as 463. This can be a can bus problem and a pro definitely needs to see this car.
