hi there

is this for the same car that has the running issue? if it is, don't run it on gas UNTIL you fix it.

if you think it runs bad on petrol, wait 'till it's on gas!! :o

your car needs to be 100% to run on gas. it's all to do with the lower rating of gas, etc.

See if THIS (http://www.carsoft.ru/avtorepair/sierra/engcntrl29.pdf) helps. Ignore Sierra it IS for the Scorpio.

theres 2 wires with a suitable rpm signal, think its secont 1 i from either end, cant remember colour. you can probe the back of the plug with a test light, see which one flashes, can get rpm signal from crank or cam sensor also.
