Hi,

What you listed, ISO9141 isn't a diagnostic trouble code. Instead, it is a communication protocol. Were there diagnostic trouble codes found? Usually, they will start with the letter P.

As for the hesitation, I have a few questions. When was the last tune-up? Have you checked fuel pressure and for vacuum leaks? Have you checked the air filter to make sure it isn't partially plugged?

Let me know. Also, here is a link that explains how to test for vacuum leaks. Try this and see if anything is found.

Let me know.

Hey, thanks for the help, Joe! I did inspect the things you listed, and also connected to OBD2, no codes popped up, and everything seemed to check out fine. It will start up and idle with no problems. Until I press the throttle and then it bogs down and wants to shut off.

Hi,

If fuel pressure is good and you covered the aforementioned items, then it may be a good idea to try servicing the throttle body to see if that takes care of the issue. Here is a link that shows how to do it:

Also, can you let me know what the fuel pressure was when checked? And, if your scan tool has live data, let me know what the short-term fuel trims are.

Take care,

Joe
