1999 cougar problem

I just replaced the timming belt and tensioner and since i got it back everytime when i take off it starts doing something, like misfre, then it runs fine, then it runs fine for the rest of the day, then all of the sudden it does it again, i took it to auto zone and they told me it was the wires or spark plugs ,i bought them and still nothing, does anybody think it may be the coil or probably dirty injectors or fuel filter?

Im assuming you have the I4?

I 4? ?????

I 4? ?????

inline 4

bad coil pack likely.

I'll buy the coil pack see what it does.

i bought the coil, change the fuel filter and still does the same sh#*%.... and now Autozone is saying the machine says it's the 02 sensor, could that be it? this fking car is driving me crazy.....:banghead:

i replaced the 02 sensor and ......same f*&%$ thing, i'm going crazy with this stupid car...:cya:

an 02 sensor would definetely not cause a misfire. It has no control over that. Its located AFTER combustion has already occured.

Have the codes read from the computer and write them down and post them here for us to see. That's the best strategy right now. :)
