Fuel injector code

[Timmytom]

I had a fuel injector code but it wasn’t misfiring at all. I checked he wiring and it was fine and then I changed the injector itself. I cleared the code but it keeps coming back. After this my trans is shifting down really hard and it feels like the rear end vibrates when I’m on the throttle about 30-50% but any more or less than that it’s fine. Idk if the fuel injector could’ve caused all of this or not. I don’t know where to go from here or what the problem could be so if anyone has any information that could help it would be greatly appreciated.

What is the fuel injector code? Look at the bushings in the rear end cradle and suspension for the shake. I would scan the TCM for any issues.

The fuel injector code is P0201-00. I’ll take a look at everything else you said tonight. Thank you.

Have you checked the wiring in the fuel injection wiring harness? Maybe a broke or stressed wire for #1?

Yes I checked the wiring harness on it with the light. Another thing I jsut noticed is my throttle position is at 22.13% and throttle position sensor is at 16% with the key turned forwards. Is that supposed to be 0 or am I wrong about that? And if so I would I fix that?

When you say the code keeps coming back is your CEL still coming on?

So I believe it was jsut a loose wire now. The check engine light was coming back on and I jsut started man handling the wiring harness and cleared the code and every problem is now gone. Thank you for the help.
