About the injectors, if the Vic has flex fuel you'll have to swap your injectors for the mustang ones.

As far as the swap goes basically take everything off the mustang engine and put it on the crown Vic, pulleys, valve covers, and accessories. I'm not 100% sure you have to swap the valve covers though, I did on mine because the valve covers on the engine I used were damaged. When you're done the crown Vic engine should look exactly the mustangs engine once you're done. I do recommend buying new gaskets. I needed an oil filter adapter gasket as well Intake/valve covers gaskets and rear main seal.

What's the issue with the injectors though? Are the mustang ones damaged? I just did the swap using a 07 grand marquis engine and it's pretty straightforward.

Oh ok cool, to keep things simple just use your mustang's rails and injectors and you should be good

Full list of everything I need to use from mustang that you did please?
A full list? Yikes! Lol I'm only saying that because I had help from a much more experienced mechanic and he did do some work while I wasnt there. Lol but put it like this, the only thing that should be left from the Vic is the block, heads, Intake if you're using it (I used the one from my mustang because the new one was cracked lol) ALL accessories (water pump, ac compressor, etc) as well as sensors are to be swapped from the mustangs engine. Im pretty sure mechanic swapped the pulleys as well. Remember that the PCM is going to look for everything that was on the Mustang. Trust me when I say it's a lot less complicated than it sounds.

I'm not 100% sure on the oil cooler though, I remember seeing a thread when I was doing research for my swap, I'll try to find it again.

Like I give it any gas car gauges go crazy then restart
Are you throwing any codes? And if i had to guess it sounds like you may not have all of your grounds connected. I could be wrong but i was having a similar issue with my gauges sweeping and the car would stall out... I was missing the ground that goes to the driver side motor mount bolt.

I'd check grounds and check your connections on your harness. make sure they're clean, fully connected and no corrosion.

I would say its safe to assume you did the swap right since youre able to get it started. You shouldn't have to remove your engine to check your grounds. I think theres 4 but i only know of 3. I have a ground from the block to firewall, block to motor mount bolt, and the last is the small black wire that's upfront near the driver side head light.

I'd hate to point you somewhere else but id ask about this issue over at stangnet in the sn95 4.6l mustang tech section. One of the guys there is SUPER knowledgeable when i comes to our cars. His name is wmburns. You can either pm him or post and wait for an answer.

Here's my thread on stangnet so is its easier to find him...
