Hello my name Jay and thank you for your question.

Do you have any codes stored after you replaced the throttle chamber? Also where did you buy it?

Customer: replied 9 months ago.
P0507 i cleaned throttle right after that I tried to take it for a spin and the slip light kept flashing and car would not let me pass 5 mph so i purchased a Hitachi throttle body from Amazon

When it comes to after market electrical parts, they never tend to work right. What did you clean the throttle chamber with?

If you are getting a P0507, that means it did not take the idle relearn, so you would need to try to do it again. It's tricky to perform manually. Plus when you do it manually, you don't know if it accepted it.

I used 3m throttle body cleaner and clean mircofiber towel. I reordered a Throttle body OEM. I will install and have it towed to dealer and have them to the relearn. New code today P0113
Expert:  Jay replied 9 months ago.

When it comes to the Electronic throttle chamber you can't use regular throttle chamber cleaner. You need something that is more for the Electronic throttle chamber. We use Mass Air Flow Sensor cleaner since it's a electrical cleaner and it won't damage the Throttle chamber.

That P0113 is a intake air temp sensor. That is part of the MAF sensor.
