Just changed plugs in my 01 GT...

After reading all the information I could find on the net about changing the plugs, I decided to try thre Autolite 764's. All I can say is this is the best mod to date maybe only second to the Pro 5.0 shifter. I went with the Autolites cause they were cheap and readily available at Wal-Mart. I haven't really noticed any ping or detonation with my 01 GT so I didn't feel I needed the Holy Grail plugs. After the computer began to re-learn the settings, the car ran flawlessly. The car idles much better and accelerates so much smoother. I never could get smooth shifts either but now the transition between gears is very smooth. The bucking is gone as well. I can't believe that changing to a cheaper, copper plug could make this much difference but I am glad I did it and wish I would have done it sooner. If any of you out there haven't changed your stock plugs....do it, you won't regret it.

This is exactly what happened when I changed to NGK TR55 plugs. I didn't think a plug could make it shift so much better, but I was wrong. This whole time I just thought I couldn't shift right. I guess the stock platinums just plain suck (only 15k miles on them).

I got some TR55's today....only changed one plug before I decided my engine was filthy and needed cleaning first....didn't want that crud getting inside. How long did it take you guys to do the job? It looks like it going to be a pain in the @ss on the passenger side!

Where the hell are the plugs. I'm no mechanic, but I rebuilt the motor in my camaro when I was a kid. I mean I have mechanical common sense. But hell I was just looking the other day and I thought ... **** where are the plugs. Hell, where are the wires for that matter. Obviously, I dont know anything about this 4.6

If you look under your fuel rail you'll see a black plastic cylindrical shaped thingy...that's a coil...you'll see one alternating between injectors. take out the screw holding the coil in and pull it out. Deeeeeep in the recess, you'll find your plugs. Hope this helped.

It should take less than 1 hour to replace them. The passenger is no harder than the driver's side. You just need to remove the air intake hose from the TB to the MAF. All you need is a deep spark plug socket and an extension. That's it.

Changing plugs is such a good idea. I too noticed a smoother acceleration after putting in some NGK's.

I just finished changing the other seven plugs. Only took an hour plus an hour yesterday to gap all the plugs and change one plug. I'm sure I can do it in about an hour next time. Gapped em at the stock .054. Gonna go drive...so far only noticed that the idle is MUCH smoother.

No you don't have to remove the fuel rail but make sure you have a very long extension because the plugs are set deep and you have to be able to clear the fuel rail to break them loose and to be able to torque the new plugs down properly. There is one plug on the passenger side that is a pain because there is something connected to the fuel rail right in front of it that cannot be removed. You will have to work around this. This created the most problems for me. The driver's side will take you hardly anytime at all but the passenger side is a PITA. Remove the intake tube from the throttle body and that will greatly help but it seems like a much tighter working space on the passenger side compared the the driver's side.

I was wondering how the rest of you that changed plugs got the plugs out of the hole once they were screwed out since they are so damn deep? I had to use a long thin tool with a magnetic tip to extract each plug. Just wondering how everyone else did it.

01LaserRed5,

I got a craftsman spark plug socket that has a rubber insert that grips the plug when removing/installing....cost about $2.

BTW for giggles I had my girl friend come out side and find the sparkplugs and she found them in about 20 seconds.......and I've only had the car a day and it's the first time she's even seen it.
:-P

But I'm confused, I cross referenced the stock plugs to auto light 764's but wanted NGK then they referenced to the NGK 5-1 which are too long a reach.

then looked at the NGK tr55 and they crossed over to an auto light 605 plug...

the 605 crossed over to another plug so what is the best NGK plug to run and would the long reach tr5-1 be ok to run? what the plug to piston clearence look like?

I would have gotten the tr55 but they only had 4 in stock. so I just left to do more research. It needs plugs and I never did like platinum plugs.

PS that thingy is prolly the fuel pressure sending unit to the computer.

I remember reading a post where the TR55-1's should not be used. I don't know what's up with that cross reference run around??

, what do you actually mean by this???

All I know about changing spark plugs are to torque them at the specified torque spec for our cars.

i haven't changed my plugs yet (2001 GT), does anybody know how much do I have to torque them at??? how many lbs ft??? or where could i find out this information???

thanks

I thought that people who were running NGK plugs were running the tr55's? Anybody know for sure?

Go get a haynes manual it will tell you all you will need to know.

BTW, for all that care I can change my plugsa from start to finish in 35 minutes or less. But thats the curse of having Forced induction they hate spark plugs.

Question

I have a '99 GT w/19K miles. As far as I know the plugs have never been changed. I have noticed rough idle especially on warm starts and roughness inbetween the gears especially in 1st it bucks sometimes. It seems from reading this post that new plugs will smooth everything out. Are Autolite 764's the best plugs to go with? Most people are saying that swapping the plugs is cake - I'm pretty green with this engine (just got it) - think I'll be able to do it pretty easily? I have the Ford service CD, does it help at all? I'm really looking forward seeing the difference you guys are talking about!

I too went to Autolite 764's last week. PITA on the passenger side! Took me around two hours for all 8 plugs. Gapped them at .054 and torqued them to 10 lbs/ft.

Here's my little trick to getting the plugs out of the holes. Get a piece of 3/8" heater hose (about a foot). It'll fit right over the nose of the plug and you're able to pull it right out. It'll also help to put the plug down into the hole and you're able to start threading it into the hole and it won't crossthread. If it starts to crossthread, the hose will start to slip off the plug.

No true power increase but since the car runs so much smoother it seems like it does. Just do it.

I torqued mine to 14 ft/lbs. I hope that wasn't to much. From what I read 11-15 ft/lbs. was correct torque. I hope I didn't screw up.
