So I just read throught the how to on this, but it doesn't say anything about a gasket. Is there one that will need to be replaced when I take off the TB or do I just reuse the old one?

 

Sorry, 4.0L SOHC

 

No. Or at least I didnt. I just sprayed it out with Throttle Body Cleaner, and put it back. This usually makes a big difference.

 

I figure after 90,000 miles of crap going through there, it's time. Thanks David.

 

Yeah man. Mine didnt even look dirty, but it definately made a big difference. I think I did mine right at 100,000.

 

i dont remove them. i hold it open and spray it and clean it with a toothbrush, all the cleaner goes down the intake usually so when you restart you hold the throttle to WOT to put the vehicle in "flood mode" so the injectors dont fire until it starts and you let up on the gas

 

I've got a lot of time on my hands, so I think I'm just going to pull it off. Doing the tensioner and idler pully at the same time.

 

Yeah, its no biggie to take it off. I did mine in less than an hour I think.

 

Yuck:




Glad I decided to finally do this:

 

Is there a gasket thats needs to be replaced when doing this?

 

^No. While you are doing this, clean your IAC at the same time. For some reason, it just got rid of the bucking it was doing. Runs awesome again!

 

Thanks for the info!

 

Definitely Runs better!

 

How easy was it for you to get the cruise control cable off? I never actually got mine off, so I just cleaned what I could and stuck it back on. Sure would like to get the rest.

 

I noticed it to on my Grand Marquis at about 80,000 miles. When you shut your engine off there is still exhaust gases floating around the top half of your engine. Hot gas will pass up the intake valves that are still open and as it cools it will deposit the carbon on the surface of the throttle body and intake plenum. I'm thinking about trying that spray can of Sea Foam when it warms up here in a few months. I have a 89 Gt and I had to replace the gasket that goes around the water jacket on the throttle body...it looked like a exhaust pipe in there instead of a intake ...

 

u have to remove the black plastice piece around it, if equipped, then i think a bolt or two and the end of the cable just snaps onto a little ball thing, should be able to pry it off with a screwdriver.

 

^ I forgot how, but that sounds right. Just pry it out carefully so you don't break anything.

 

Yeah I heard it's pretty difficult to get off, but I was pulling really hard and I didn't want to mess anything up. I'll give it a try tomorrow.

 

^ Open the throttle open with your hand and tug on the cruise control cable from the end with red tip on it. Mine popped right off and went back on just the same. But yes I will add this cleaning helps a bunch. I have twice the throttle response compared to what I used too.

 

Yuck is right! Maybe I'll give this a shot on my '03 soon.

 

Just did the fiance's Grand Prix yesterday because of a starting problem it had. Starts perfect now.

Exactly what spray are you using to clean the TB with, while it is still intact with the engine?

 

Straight up 'Throttle Body Cleaner' Its a no-residue cleaner that evaporates really quickly. It has a strong stream, so removing the throttle body is considered the preferred way of doing it.. jsut buy a can of it and go to town. Take off the IAC as well and spray clean all the springs and everything in there! The IAC is right next to it.. bolted to it!

^^right on dood. Thanks

 

I went out and took mine off, nice day out so might as well be in the garage. It wasn't that bad but still kinda grimy. This truck is an '03 and has just over 60K miles on it. Used some CRC throttle body & air intake cleaner I had and also cleaned the MAF with CRC MAF cleaner. After seeing the TB, it almost makes a guy want to pull the whole upper intake off and clean it but that looks like a real job. Pulling the TB off is only a 5 minute job, pretty easy.
