I just got back from getting my spark plugs and fuel filter changed at 114,000 miles..the plugs looked pretty toasted and the gaps were huge! I was wondering is there an adjustment period for the computer when going from worn plugs to new plugs? It seems every time I start the motor it skips slightly, and it just did that occasionally before the new plugs. I also cleaned the mass-air meter with mass-air meter cleaner, but I haven't started the motor since I cleaned the mass-air meter. I'm hoping to pick up another mile-per-gallon or two with the new plugs, I topped off the gas and zeroed the odometer lol, time will tell.

 

have you cleaned out the throttle body lately?

mine has 113,000 and i wiped mine out the best i could and it was extremely nasty....

get some good carb spray and some rags and clean it out, youll be surprised how much it helps

 

X2 on cleaning the TB and I bet you will see that cleaning the MAF helped too.

 

Might try resetting the computer as well. (if you didnt do it already) Just unplug the battery for a min or so.

 

Well I started it up after cleaning the mass-air meter and it was smooth. I cleaned the throttle body after that and you weren't kidding 00f150lariat, it was pretty filthy. The real mess is past the throttle body butterfly, but I don't want to clean the whole motor lol. It started up smooth the few times it started after that. I wanted to see if I could notice a horsepower increase with the new plugs, so I hit the gas at about 30 and it started to go sideways so I let off..darn salt on the roads..I guess I'll have to wait till the weather is nice to see if there's a difference.

 

When i clean my throttle body I take it off and scrub it real good. Use wire pipe cleaner on it and all. I also replaced my IAC when I did it. Truck ran much better..

 

I cleaned it very well, it's still dirty past the butterfly..I opened the butterfly and cleaned what I could reach. I think it's more responsive now, but I'm not sure if that's just because of the new plugs. I'm itching to see if my gas mileage improved..I'm guessing it would have to by the condition of the old plugs..I was averaging 13 or 14 miles per gallon.

 

Dont be surprised if the gas mileage dosent improve much. I've done it all and I still get 13-14 combined mpg.

 

Yeah it is a big hog. The thought of the elbow past the butterfly being so dirty was eating at me, so I took the throttle body off and cleaned it..dirt was caked on it much worse than the throttle body. The throttle response is much better and it feels like it has more of those nice hp's..maybe I'll wait 'till the next tank full to try for good miles per gallon.

 

It will give you more power cleaning it like that. Dont have high expectaation for incressed MPG though. Makes it run better though. I do my throttle body once a year now.

 

Thanks for the good info I can always count on this website when I have questions. Will someone please tell me how to post pictures on here so that I can share my truck with other members?

 

You have to put the picture on a photo sharing site like photobucket then link the picture..

 

Wow that's a sweet Mach 1..351 in that? I uploaded a picture from my desktop and added it to my signature, but it's not showing up..does it have to be approved first? Sorry if I'm a little dense.

 

Ok lol I guess I have to post a reply before it shows up, is there a way to make it bigger?

 

I think it depends on the pic you chose for the sig link and sigs are automaticly downsized (maybe cant remember) keep screwing around with it. youll get it.
