I have a 97 Ford f150 I need a little advice gets up to 40 mph then it starts to kick and buck but will never get pass 40. I change the coil packs, new wires, new plugs, and also did timing chain and intake gasket set. Still the only code I have is lean bank 1. If any one has any ideas please let me know.


97 F150 4.6l
4x4 lariat

 

Check fuel pressure. Look for vacuum leaks.

 

Why is the lean code being given a back seat?
It may not be causing the missing but certainly has an effect especially at low RPM where is has shifted the long term fuel table for that bank.
You need to address every know issue for correct operation.
Good luck.

 

I Swapped out the the transmission in this truck 97 f150 4r70w with one that was working fine in truck I pulled it from. Now on my truck I can only get up to 40 mpg it starts kicking and bucking but will not go any faster. I change solenoids and filter but have no luck.

 

What codes are set?
Good luck.

 

I am trying to figure out how to find out what kind of transmission is in my 2001 ford f150 4.2 v6. i need to replace the lines to the cooler but noone at the local auto parts stores can sell me one without knowing which kind of transmission i have in my truck. it doesnt have a sticker on it under the truck and i looked on the sticker inside the door it has a TR code and U under it other than that i cant find anything telling me what kind of transmission it is. Can anyone help me out? all i want to do is replace these rusted out lines and get on with my day. thanks

 

If your trying to replace cooler lines, its an automatic.
Being a 4.2 V6 the only automatic used was a 4r70w 2wd or 4wd.
Why is that such a difficulty?
Some one is not using their head!
A least get under an look at the pan shape, count the bolts and look up pan gasket shapes to ID the type.
Good luck.

 

Code U on the door is always a 4R70W.
