-ok i just put new plugs and wires in my car it has a 5.0 ho out of a mark VII the plugs are gapped at .05 when i give it lite throttle it dies but if i mas the throttle to the floor it hesitates for a second the takes off like a bat out of hell it is a 87 with speed density

 

this problem started when you did the tune up???

 

adjust the throttle position sensor.... ~.95v +\- .04v...but you need to clear the computer and reset the idle also.....

 

well i figured it out. the chiltons manual i had gave icorrect procedure to set the timing it told me to remove the spout connector and put a jumper in its place so thats what it was i figured it out it is real nice now
