Welcome to AF !

Check your injector(s) and the wiring. ;)

yes all i did is watch the voltage signal on all with laptop cyl3,
looked like the rest. and took stethie scope and all injectors tap about the same in sound. had intake off twice took every thing down and went thru
lifters and rockers, push rods seen nothing. its got a dead miss seems lean.. thanks much:smile:
i even went to the point of running 2 gallons of gas in it with 3 bottles of seafoam, it was way strong
and went out and drove the shit out of it ,, runs the same hmmmm. seams high in emmisions fails emmisions right away on tool....

Start by making sure you have compression in that cylinder.

well i got another question, do i loose overdrive and or the torqe converter
when you fire only on 5 cyl. thanks much nice site too:wink:

No.

well i guess ive seen bad tps and deadmiss fires in one cyl make the torqe
converter not lock up.
