i bought a 1997 F150 how can i tell if somebody has put a chip in it or programed it. i asked the guy i bought it from and he sed not that he new of!! lol a bit slugish fro idel changed air an fuel filters.. i had read to disconect neg. cable and reset comp. it run like crap for a while then straitnd up.. it would die when you would come to a stop in gear. but i gues it adgusted its ok now other than slugish as you start off from idel!! and gpm sucks 10.9 it has a 4" lift and 33" mud tires.. i new it would suck but not that bad lol!!! any ideas??

 

what gears are in the truck???

 

i think their stock! i dont no lol it doesnt feel like its wond to tight! i had another truck that was and you knew it. it was ordered that way for towing.

 

so you do understand that like engine size, cab configuration Ford offered more than one as "stock"??


go check your door jamb, and come back with the axle code

 

remember the truck weighs 5000+ lbs. i just bought a mustang gt and drove my f150 for the first time in over a month, and i noticed the difference in weigh and mine has about a $1000 in performance part into it.

try cleaning the maf, if it's dirty it can cause a hesitation off idle and get some throttle body cleaner and clean the idle air control solenoid.

 

Hmm - you act like a jerk in your original thread and get called out, so you come in here to see if you get treated any differently? I think you better go back to your original thread and make amends if you want any kind of meaningful help here.

 

you no i sed i was sorry but i took it that he was maken fun of me!! how have i been a jerk? im not here to start any thing im here to learn something sorry! im sure if some one was been a smart *** to you!! you would not like it and you would say so! but im sorry i took it the wrong way!!!!!ok?

 

hey thanks i done what you sed an cleaned maf. and the iac and no more hesitation thanks!!!!!! got some of the guys on here made at me because i took something the wrong way so we will see if every body keeps on helping!! i hope that i can do the same for yall sometimes!! thanks agin!!!

 

i just realized something...in 97 those trucks came from the factory with a small tire size of like 235/70R16's or 245/75R16's which is quite a bit smaller than 33". the gears are most likely 3.55's, if you call the dealer they should be able to tell you how to locate your axle code, tell them the code and they can tell you the gear ratio. if its 3.55's now, i would recommend 3.73's or the next gear lower

 

I can tell you right now that if you crawl underneath your 97' and look on the rear diff that you will have the gear ratio listed right on a little riveted plate

jtfflying - Not to start anything or make the experience of these forums anymore confrontational for you.... but... It is VERY difficult to gather the meanings of even a single sentence you are typing. A combination of misspellings and the use of completely incoherent words make it very difficult to follow. Again, I don't mean to offend, I just wanted to say that at first I didn't help because it was hard to even understand you. For the misspellings you can right click on words underlined in red and choose the correct spelling, if you do that one thing it will make it much easier for us to help in the future, which we are all here to do

 

it's even easier if you go out and look at your door tag...

 

Look for a sticker on the drivers door jamb.

It should have a lot of info on it.
You should be able to find axel code. #9
19 – 3.55 Non-LS
18 -- 3.08 Non-LS
H9 – 3.55 LS
B6 – 3.73 LS

 

ok that helps a lot the code is axel#19 so does that mean 3.55's and what does the non-LS mean not limited slip? is it positive track or what?? thanks for yalls help!!

 

Non-LS = No Posi

 

you need a re-gear
