The gas tanks on the new edges tend to leak at the fuel neck down where it connects to the tank. Mine was replaced last year for this problem. I had less than 60k miles at the time. If you still smell gas, I'd look into to that. You can check for leaks in hoses and the evap canister itself. That could cause fuel smell too. According to AllDataDIY, it's located under the car on the drivers side rear. It says to remove the driver's side wheel to gain access. I think I remember seeing the rear of it on the backside of the rear wheel well.

Check for vacuum leaks and cracks in the manifold. Also make sure there are no air leaks after the MAF sensor.

I am new to Ford and modular engines, but I am learning that this particular design is extremely sensitive to any changes or minor problems.

Be patient with me and I will answer in a bit. I'm dealing with pain meds at the moment, and I am not thinking clearly enough to give you answers I trust.

I am betting that someone else comes along shortly though with the answers.

I would begin by looking for physical cracks.

The 4.6L 4v's didn't have plastic intakes, so I doubt you have a crack in your intake. It doesn't hurt to check.

Read this I posted below. I'd work on finding the gas smell first. Mine leaked where the fuel neck goes in the tank. I needed a new tank. After that, look on the drivers side rear where the evap canister is. If it leaks, I believe it will cause gas smell too.

You should probably use your tuner I grab all the CEL codes you have. That way you know where to go next.

I couldn't find a diagram of all the vacuum hoses, but you can start at the top of your EGR valve and check the hoses back up the system from there.

Yeah I was just wondering if there was a way to check for leaks without having to jack the car up and physically check the lines. I don't have a tuner on the car btw I have some $30 thing that reads codes

This is where I would begin. Have patience and be thorough as you look at everything. Find photos, and look at actual cars to see routing, mold lines, etc.

Sometimes these things require baby steps.

The $30 code reader thingy will work fine.

Unless you are physically, generously proportioned, shall we say... Or your car is very low... You should be able to squeeze underneath the car with a flashlight, near the fuel filler tube, and inspect it for any signs of fuel leakage, rust, rot, disconnected hoses, or any other sort of damage.

Haven't had time to check out the gas smell but a couple of new issues have came up that concern me, first the car is now starting to pop at w.o.t and it still has a slight hesitation around 4k rpms. The idle is also not sounding right like it's idling normal then all of a sudden it'll sound like it stumbles. Also 2 other incidents happened where I came to a stop and the car started idling at like 600 rpms then it went away after I took off, then last night it barely cranked up after I moved it just 15min before

Probably a good idea too, especially if it's the original. Bad alternators make our cars do all kinds of stupid stuff lol.

Check the fault codes and work them. After you find something, clear the codes and see what comes back. Fixing the first fault code you got might take care of the others.

But would a bad alternator cause my car to hesitate? Cause I've had that issue ever since I put the off road midpipe on

It could by way of messing with the crank sensor. But, I'd say it could be that there are leaks before the O2 sensors(not the rear ones). The O2 sensors could be bad (not the rear ones). It's best to follow the fault codes and troubleshoot them. That will put you in the right direction rather than any guessing.

I've had random hesitations before that didn't raise a CEL and have a fault code. The problem has to happen enough times for the PCM to figure it out and not put up a false code. A lot of times, the COP's will have problems before it will throw a CEL. Did you change spark plugs around the same time as when you put on the off road mid pipe? Did you get the O2 sensors connected completely when you buttoned it up? Did you touch the O2 sensors on the tip when you handled them? That kind of stuff. But I remember you mentioned there was an evaporative system code. I'm not completely sure what all the symptoms can be for probs with that, but I'm sure it can mess with how well it runs along with fuel smells etc.

Put your modus on the car and look at the data. Check voltage at different rpms check o2 sensor readings

I would work the evap leak. Once you get a tuner, you'll be able to turn off the rear O2's. Here's some info about the evap that might help.

I agree with ab mach. You need to get rid of the sizeable vacuum leak that is causing the evap code before anything else.

The whooshing sound is likely the vacuum leak that you are hearing.
Did you find anything?

If you are talking about the one that is pointed to here, that's a vacuum line.

FYI, the Ford COP's are the best. I know they are more expensive, but well worth it as far as reliability goes.

You can buy them from Autonation Ford in Minnesota. I've ordered quite a few Ford parts from them lol. They usually have better prices than your local dealership will have.

Those COP's can have intermittent problems leading up to them failing completely and they often won't throw a CEL. If they are the originals and you have a lot of miles (over 90k), you're better off buying all 8, cause they'll all start to go lol.

Yup, you're gonna need to troubleshoot this evap fault codes. I'd do that before I bought any COP's if it were me. Don't feel bad though, all cars start having parts fail when they get to higher miles. My other two cars have over 160k miles and we got through the first round of issues on one of them. I just hate having a big *** car payment.

The car has 82k on it now and it's always had a slight hesitation but now that slight hesitation has turned into a big one so I'm guessing one went bad
