does anyone know the correct timing on 97 ford 4.6,what is the procedure

 

Can we ask why you want to know this?
Pretty sure you cannot change it. Set by crank sensor & crank pulley I believe.

 

just wanted to check.Have truck running fine when first started .After it runs for about 5 min it seems to loose a little power,Also seems to idle a little rough.showing no codes tks

 

There are several things that could contribute to this problem.
It is important to know,
When were spark plugs replaced
" was fuel filter changed
Did this start shortly after purchasing fuel
Did you look for / check for any vacuum leaks (cracked hose/ hose came off)
How does it perform out on the road when throttle is depressed and demand for more fuel takes place
If it idles a little rough ,but clears up as engine speed is increased usually are signs of a vacuum leak somewhere.

 

changed plugs, ff,can't find any vac leaks,When its cold it runs great,after it warms up seems to hesitate a little,also idle is a little rough.not real rough but i can see difference from cold to hot,no codes

 

those engines don't have any way to adjust the timing because the pcm does that for you.

 

just got 172 code took maf out and cleaned it .drove for about 1 hr came back on can't find any leaks,

 

If the code P0172 is a new code (not from anytime past) it is telling us that bank 1 is running rich.
Anything the MAF sensor is involved in , will concern both banks since all incoming air is supposed to come past the MAF sensor.

If you don't have access to a scan tool to get O2 sensor and fuel trim readings , what you can do is pull a spark plug from each bank and compare their color. The bank running rich might have plugs with a more black color.
Bank 1 is the passenger side and you could look for anything unusual there. An O2 sensor that is sluggish or sticking rich could produce this code. If the O2 sensors have never been replaced since new , it wouldn't hurt to replace the one for that bank.
I always suggest using a Motorcraft sensor specifically for your vehicle/engine.
If you have no other choice I guess you have to use what you can get and hope it is the correct one and isn't bad out of the box.

 

tks one of them is mc,one came from oreilys.No 2 is mc, 1 is generic.

 

just desired to examine.Have vehicle operating excellent when first began .After it operates for about 5 min it seems to reduce a little energy,Also seems to nonproductive a little difficult.showing no requirements tks
