Get the most out of stock

[The Kraken]

Ok so I purchased my 05 GT last weekend and she is just over 62000, the low mileage is nice but it's obviously a hard 62k. In my contract I got them to replace the clutch (happening wednesday) and address the check engine light (seems to be the common TB sensor problems and what not and I'm assuming when they send it to the ford dealer the TB will be replaced)

So I am trying to get her running as best as possible in stock form before i start the modding process Id like to get a starting dyno. I'm going to replace the battery with an optimum red top, run a fuel system cleaner trough, probably replace the belt, clean the filter or possibly throw a new one in it. I'm wondering if there are any stand out options for these steps and also if there is more I should check / do. It looks like the oil change was recently done by the dealer so I'll wait to 65k to do another.

Thank you for your responses in advance!

This... Plus rear end fluid under the circumstances... I'd also suggest a good synthetic fluids all around.. Like RP or Ams Oil

I'm not really worried about the car much I checked it pretty good and new what I was getting into and was able to get it with the dealership losing money lol I was dead set on an 05+ GT and this was the only reasonable option all I'm trying to do now is get here in top shape to start the building so it's all just tune up type stuff

I was also looking to go the fully synthetic route with all the fluids but I know some cars don't play well with certain products but it seems like the mustangs are fairly good with most

[The Kraken]

As far as blow by I'll be checking the plugs tomorrow need to search the firing order but i don't have a compression gauge maybe i should grab one at advanced tomorrow??

[The Kraken]

Alright so iv been searching around the forums and web but i need to start moving now that it's noon lol I'm going to go grab the battery, see if they have a belt in stock, I think iv decided on a fully ams oil synthetic oil change and filter, I'm going to see If they will do the trans fluid while they replace the clutch. I'm going to hold off on the plugs as I'm seeing some conflicting info on change intervals, kind to go with, and that there are sometimes problems taking them out.

Didn't get much done Sunday late start early finish. Can't find the optimum red for my car at autozone or advanced so I'll prob just order one. Couldnt find amsoil in either never used it before but it looks like I'll have to find a dealer in Virginia beach the website shows names of dealers but not the shop / store they are at. Here's what I did manage not that it's much lol

Should see some mpg improvement from the injector cleaner and replacing that horrid looking motor craft filter lol

Lol it works just fine and is ice cold, I had that left over from a friend and was going to check the low pressure valve just for Sn giggles but it didn't fit haha

It looks like ur headed in the right direction. The first thing I did to my 06 GT when I bought it was CAI, SLP loudmouth and SCT tuner. The difference in the performance just with that was amazing. Well have fun with her.

Yeah it's here in Chesapeake right on the VB boarder, trying to stop in ASAP but I work second shift so it's hard to get there. If there's anything anyone would like to know while I am there i am completely down to relay questions

Also, change those plugs, even if they said it was done recently. Motorcraft or Autolite is all you need. Some here like NGK's, but no fancy plugs. Make sure you use anti seize on the threads and dielectric grease on the boot so you get a good connection from COP to plug.

Ok thank you I want to change the plugs but I keep reading that they are prone to snapping in half I'll prob have a mechanic go after them and I think I'll go with motorcraft

Just make sure to ask them to put anti seize on the threads as this is the primary reason the snap off The other reason is changing them when the engine is too warm.

I too was worried about this when I changed mine for the first time. I just didn't trust anybody to be careful enough.

Well now that you put it like that haha maybe I will just dedicate some time to doing it myself very carefully

Exactly what I'd do. A buddy took his to a shop that broke 6 out of 8 plugs on his f150 and it ended up costing $1500 for a tune up. They get paid to break them. The plugs on a mustang are the easiest of any car to change.

Yeah I can see they are super easy and iv changed plenty of plugs on harder cars but when I ran a search to find the best plug option it seemed like all that came up where horror stories but you guys def convinced me to just do it carefully myself and I'm sure I should thank you now lol
I would really love to start modding but i want to be smart and start from a well oiled machine first plus I wont have to worry about what maintenance is done because I'll know it all has been by me haha

It's actually a design flaw on the F150 4.6 and 5.4's during a certain year span. The plugs were basically stuck due to corrosion causing them to break while trying to remove. Moisture getting through the coil/plug boots are the culprit. When you do change them there is a new part number on the motor craft plug and you have to replace all the coil boots at the same time. Pretty pricey plug replacement no doubt.

Good info thank you for the heads up!

Pretty sure it also has to do with them being two piece spark plugs more so than anything else

So the COP design has changed from that time as well?
