While sitting idle or holding acceleration my car stutters and shakes like it wants to shut off

Hi,

Based on your description and what you have already done, the first thing I suspect is you have a partially plugged catalytic converter. By chance, is there any smoke or strange odors, or odd sounds coming from the exhaust?

Take a look through this link and let me know if anything mirrors what you experience:

Also, is the check engine light staying on while the engine is running? Also, have you tried having the computer scanned for diagnostic trouble codes? Most auto parts stores will do it for you free of charge.

Let me know as much as you can. Anything you can think of that may help me diagnose the issue will be helpful.

Take care,

Joe

Hi,

Is pic 1 going from in front of the engine to the transmission? Also, is the leak right where it starts being covered?

In pic 2, I can't tell what is leaking.

Let me know.

Hi,

That's a transmission cooler line. There should be 2 of them. One is the supply, and the other is the return.

There are several different ways that can be attached. Some simply screw in, and others are a special connector. I believe this vehicle will have the screw-in type.

Since it's leaking, it could be loose or even have a small pinhole in the steel line. I attached a pic below showing what I believe you will find if you continue following the hose to the cooler. Also, I believe the cooler is not part of the radiator but a separate cooler in front of the radiator.

Let me know if that is what you have.

Take care,

Joe

Hi,

The worst part of this is if it needs to be replaced. What makes it difficult is routing the new one into place. Other than that, it is a straightforward job.

I'm here to help if you need anything.

Take care,
