Hello, I am the proud new owner of a 94 Thunderbird LX. I really want to customize the car, exterior is in good shape, interior too. I bought the car because the price was right, but it has engine problems. The seller didn't know what was wrong, but from the short drive I took, the car is definitely down on power. Seems like it is running on 7 cylinders (or less) or something, it is kind of choppy and really doesn't have any getup. It runs very quiet and starts with no problems. Motor has 162K on the clock.

Any ideas or suggestions would be greatly appreciated. I have had a few people suggest a full tune-up (plugs, wires, filters, etc...), problem with coils packs?, wiring problem, bad computer etc....

Thanks alot

Definitely do the plugs and wires!

These cars are very very sensitive plugs and wires. (Do some searches for recommendations on plugs)

The next thing I would do, besides replacing all the filters, fluids, etc. is clean the MAF. With those miles, it's probably filthy. Do a search here and you'll find the ways to clean it.

You'll probably notice some oil smoking if you idle for a while and then pull out. A large blue cloud will roll out! :eek:

That is a common problem with the valve stem guide seals on the early 4.6L's. It's not hurting anything, just looks really bad. Another search will help you get that fixed. :thumbsup:

And welcome to the club/board from a fellow 94 LX owner!! :wavey:

Thanks for all the help. I will definitely work on all these things, the check engine light is on, so I need to get her coded. I am going to try to pick one up this weekend, someone said Walmart sells one?? If not I can go to an Auto Zone or something.

I am glad to have joined the forums, thanks once again everyone!!!

ya, AZ will usually scan the codes for free and tell you what the problem is.. but they generally don't have a clue on how to fix it.

since you have a 94, don't plan on cleaning the IAC, cuz if i remember right, if it is where i "think" it is.. you might as well just put a new one back on cuz it a beotch.

when the codes get scanned.. go ahead and post them up on here

and when you go, tell them.. YES I DO HAVE OBD-II... YES, IT IS A 94, will you PLEASE just scan my damn car??

:D welcome to the boards

When you work on that (explative deleted) IAC, be very careful not to drop anything down into the intake. Your motor will eat it causing major damage (unfortunately I know this from first hand experience).

Idle Air Controll I believe.

The Idle Air Control (IAC) is what controls the amount of air coming in the engine at idle, so if its bad or dirty, you will have a rough idle or it won't idle at all.

it is located on the driver's side of the intake plenum/throttle body. It's a silver tube with a head that has 2 bolts holding it to the intake. It also has an electrical connector and a black cap-like vent sticking out the sides of it. Might need to move some wires around and then you can see it with a light.

When you remove it, it will be obvious where to spray the cleaner.

Any quick recomendations on plugs? I have searched and looked through a bunch of posts, but feel like the results are mixed. At this point the car is stock and will be for a short time, so whatever works with stock will be acceptable to start with.

Also, the IAC - Can this be bought at Auto Zone? Any idea how much?

Thanks

Jeff

IAC is generally a dealer part...

prepare to get raped on it.. i think they were almost $100.. either call Dan, Max, or check for a newer takeoff..

Gnerally for a stock car I think Motocraft AWSF 32 will be the number. Be sure to get coppers and not platnums. Might be a F8 or something after that, just to denote they come in packs of 8.

The IAC is going to cost you around $55-$65, from a Ford Dealer.

You may want to purchase an inexpensive magnetic pick-up tool, and use it to remove the two bolts that hold the IAC in place, after you loosen them. If you drop them, they will end up somewhere where you can't get at them.

Greenersport;

PM me with a mailing address, and I will send you a copy of the service manual on CD.

when i pick up my 94 it is running on 6 cylinders instead of eight. the previous owner spend tons of $$$ try to figure out which failed. i spend 80 bucks for a eec and running v8 again. my code is about misfire. if after tune up and maf cleaned and still the same code then i'll say is the eec. my old tbird is also a 94.
