Backfire is all fun and games until someone calls the cops thinking it's a gunshot... lol

Thank you so much for making this video. You actually help me fix my own car. Therefore saving me a ton of money 🚙💵💜

Great video. I like the way you went through each step thoroughly. Engines are a SOB when there is a certain problem and you really have to go through a trouble shooting checklist just like that.

I have a continuous backfire on my throttle body injected 318 in my 1990 Dodge Ram while driving at cruising speeds, though I believe it’s caused by a rich fuel mixture due to a strong gas smell. Any ideas on how to diagnose/fix? Thanks!

Just had 351 firing through carby under load in 4th gear down low RPM, vacuum line to the advance unit on the dizzy was old and loose,  cut the line a little bit back and refit it back on and there you go, I don't know if it was the vac leak or the poor advance alone or a combination but there is no backfiring now

I have a Harley that backfired when it was brand new. It only started after I took the factory mufflers off. The small afterburn that I’ve heard in every Rx-7 that I owned, when I put the flow masters on my mustang, but the Harley (fuel injected) can sound just like a .45 shot if I take off wide open then let off.

Haha! I just got a 1990 corvette ZR1 has back fire only when decelerating. I was not feeling hopeful, up until the end of the video! I'll have to check tomorrow and see if it's the valves

On chevy 366 gas engine its always been a broken valve spring/ bent push rod or woren cam lobe.

DO NOT use carb cleaner on a MAF! There is a specific MAF cleaner available which will not damage the components of a MAF. Carb cleaner is too strong!

Im getting a small evap leak code...and small popping sounds while stopping at lights or stop signs?

I need help ! I have an 02 Buick lasabre. Upon acceleration i lose power once the engine warms up. Even worse on hills. But once it backfires it seems to gain back some power to pull the hill

🤣 You’d make a fortune setting up shop in my south Florida neighborhood .

If fuel delivery fails, there isn't as much fuel as usual reaching the piston chamber. How then would the fuel mixture be rich?

[nighthawkval]

change the engine .
Lol ! I’m joking!
Great video help me a lot thanks!

Actually, backfiring at the rear exhaust is a good thing....cuz it sounds cool.

I replaced the valve timing solenoid in my 2001 toyota avalon and it runs much better. No misfiring and idles at 800 rpm. Check engine light and VCS lights are back on. Any suggestions??😊

[thunderjet]

How bout on a car that has no computer or fuel injectors?

[toddreeder]

Is it normal for pro charged vehicles as well? Specifically a 6 speed manual between gear changes

Dear it happens sometime if your cam senser is not working properly or have adjustment is needed
