Backfiring
My 5.0 has just started intermittently backfiring at low RPM's and seems like I'm loosing a cylinder, but when I give it more gas and get to higer RPM it picks up again. I'm thinking either the timing chain or injectors are going bad. any input?

hmm, I didn't think of that. I have a K&N intake on the car. It's been on the car for a few months now and no problems until now. Funny thing is I only run 89 or higher octane. I need to fill up and the local gas station only had 87. This didn't start happening until I used that crappy fuel but since then I've used octane booster and I have filled up with 93

Question: Is your gas burning faster too? That's what mine did. |
yeah, it seems like the gas is burning a bit faster. and the check engine light is on, but it goes off when you hit i guess a certain airflow or something idk

I noticed: Back Firing Trying to die at low RPMS Weird Smell Back Firing when down shifting. Fuel burner faster |
I've got back firing and faser fuel burn, but thats it, i think the check engine light could be the 02 sensors though. I can hook it up to a diagnostic check for like $35

Any autoparts store will read that code for free and then we can help you figure out whats going on with your car.

I was thinking it was the O2 sensors. And I misdiagnosed my car, it is back firing but its also misfiring, thats what i was refering to
|
gas burning faster??
What?? I hope you mean lower fuel mileage! And not any parts store will retrieve codes for free. That year is not OBDII. Most parts stores that do that in my experience only to that on ODBII equipped vehicles which for the most part is 96 and up. Good luck.
