Hi everyone, can anyone help me out. My engine fires up perfectly.I give it a bit of throttle to warm her up before throttling back and engaging the gear.The problem I have is when I engage the gear she stalls out. She has a twin barrel rochester fitted but I am a bit unsure as to what adjustment I might need to make.Any ideas.:confused:

Re: Idling problem 1989 3.0l cobra

this sight will help . but i think we could all use some more info ...
1= does it idle when its warmed up ?
2= what is the timing set at ?
3= whens the last time it had a tune up? i.e plugs, cap, rotor, wires, points, condenser . etc
4= fuel condition .. bad fuel ? fuel filter?
5= was it sitting ?
one thing i can tell you for sure .. dont shift that thing into gear until you get it running at a smooth idle at low rpm ..

If it idles ok after it's warmed up, and only dies when you try to put it in gear, you probably are due for a new lower shift cable. It's stiff and engages the shift interrupt switch which kills the ignition.

Nope, it's broken ;)

I really wasn't jumping to conclusions about the cable, for the simple fact that he mentions WHEN it dies.

The problem I have is when I engage the gear she stalls out.

Which is EXACTLY what happens with a stiff shift cable.
