Hesitating Bronc

[maddogv21]

So my bronco runs fine when I start it in the morning but once it gets warmed up it starts running a little rough. Not as much power, hesitates a little, and the check engine light comes on. Thought maybe it was the O2 sensor, so I put a brand new one in it.....that wasnt the problem. I can take it t autozone and hook it up to the diagnostic thing for free, but I thought I would see if you guys might know something........Any thought would be nice, Im thinking it might be the TPS now....???? What do you guys think?????

For my 2 cents. I think it would be foolish to just start swapping out parts when you can get the codes for free.

Yeah I know. But I was so sure that it was the O2 sensor. Plus I didnt know I could do the diagnostic for free til yesterday.........Im obviously not going to change out any thing else til I run the test. Thanks for your input though

Yep... autozone offers a great service.

BTW... welcome to the Zone

you will find that there is a bunch of really great guys here that are more than willing to help each other out, so if you have any questions, don't hessitate to post them.

Miesk5 put together a pretty informative thread on self testing.

You can do it for free at home, and without specialized equipment, if you can't get to autozone.

I just had another thought about its loss of power after it heats up. That could be caused in part by a dirty air filter.
