x24-7x

Ok originally my car would hesitate/backfire a lot of times around 2500 or more. Then it started to where it took about 5 seconds for it to start. I got my codes ran and it said my 02's were leaning out. So it possibly could have been denonating? So i replaced one of my o2 sensors (havent replaced the other yet, will be doing today, along with fuel filter). Its still having the same problem except worse. Last night i got on it a bit and it took till about 3500 to start to hesitate and then when i got off the throttle it died. I tried cranking it about 5 times around 5 seconds each. Finally it started. Now this morning, it is freezing outside, and it wont start. Cranked for almost a minute, several times, letting the fuel pump prime, and it just wont start. Any help is appreciated i need it quickly!

Checked spark? Sounds like an opti issue.

What year is the car? What were the EXACT numerical codes? Have you ever checked the fuel pressure?

I actually need to get a fuel pressure guage. So no i havent, but i believe either my coil or opti is bad. I had my ICM checked and it was fine. I actually have another coil so im gonna try that and see how it goes. I really hope it isnt my opti. lol

Any good (easy) write ups for a coil swap? Sounds like what I am going through right now.
