Bought yesterday while driving home after about 2 hours car started shuttering around 55 tach was moving all over. Fluid levels look good car not running hot . In excellent condition for its age . Next day car starts and runs good but when you drive it cuts out under acceleration and also died a couple times . Also during all of this the throttle got stuck open . Got it home it runs and idle good still cutting out any ideas !!!!

 

My first inclination would be to address the sticking Throttle issue. Would not want that on a highway! May just need a lube job. If i's fine when started, perhaps it's a heat related issue on the cable. I would pay a great deal of attention to that cable. If it starts from cold and starts cutting out once warmed up, I would suspect the coil, or the wiring to the coil, or the ignition/injection grounds located on the RH side of the engine at the rear of the intake manifold. Just my two cents.

 

Thank you I will start with that is the 79 considered a series 2 or 3 try to find the throttle cable

 

Series II

Nice looking Jag. Stately color. Congrats.

 

The second tank ended up having bad gas . I cleared the fuel line changed the fuel filter plugs and the coil . Took on a short drive today and I made it home 🍾. Still waiting on a new throttle cable. Also the fuel filter was under the air cleaner
