Re: 4KCSQ: stalling at cruise speed

[rjandrew@post.cis.smu.edu (R Justin Andrews)]

You are correct!!!
My distirbutor on my 5k used to do this occasionally....
It caused an intermitent miss at idle....
The thing that sucked was one of the wires got hung up inside there...
snapped it and tach dropped to zero.... nothing...
coasted under a street light and fixed it with some extra wire in the 
glove box....
I don't know though... When the fuel pump crapped out on my 5k the 
tach dropped to 0 immediately....
I thought the FP relay controlled spark as well as fuel...
not sure though...
checked fault codes after this???
don't shut off ignition switch and dump em....

HTH!
