Hi all been awhile for me on here been dealing with another truck my sister 2001 Toyota, finally got it back in running shape. Well i just turned 240.000 miles on my truck pretty good for a 4.7 been real good to me, but thinking it time for some more work on it, power still good, but can smell gas from tail pipe, any thoughts beside checking the plugs any sensors i should look at,

 

Is it throwing any codes and if so what are they?

 

Have not shown any codes would it show codes if the check enhin light does not come on, I will have it scanned next time am in town.

 

Turn the key off and on 3 timed but the third leave it on and look where the odometer is.

 

Not showing any codes

 

Just checked cleaned and re-gaped plugs they were running 44 to 48 book say 40 i put them at 38.5 to 39 after done crank it up and RPM's were 100 less so that should help with gas
