Ford Mechanic: Mike V., Auto Service Technician replied 4 months ago

The truck has a mass air flow sensor. You symptoms sound more like an ignition issue. If you have a bad coil it can backfire causing the pop in the intake. Usually they will also fail more when the weather is wet. Sometimes you can mimic the problem by spraying some water from a spray bottle on the coils while the engine is running. If a coil is failing there will be sparks arcing and the engine will run rougher.

You can try cleaning the maf of course, but it really sounds like you have an ignition issue.

Ps new plugs ps new wires or new coil. All 2 weeks old ps new throttle pos sensor hah now what how bout crankcase sensor.l got a really good feeling this is going down the rat hole I got f**ked out a 38 clams couldn't got another f**king part hah
Ford Mechanic: Mike V., Auto Service Technician replied 4 months ago

Sometimes it does help when you let us know what you have already done so we aren't wasting either others time.

Try unplugging the maf sensor. Then start the truck. If the performance is better, then replace it. If not, then you know it's not the issue.

I would still spray some water on those new wires and coil just to be sure. I do understand you are frustrated, but I am trying to help, not be a punching bag.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
