Hi to all, my jag is saying cruse not available and its running real rough, i noticed there was a crack in the hose from the top of the engine where the pcv valve is so I replaced the hose and pcv, there was no change, any ideas ??, the car has no power its like it bogs out when you try to move,, Help !!!

 

Pull the codes You probably have P0171/P0174 /P1000 OR check further for vac leaks in the plentum hoses from the brake booster and egr assy. also there is a line running behind the plentun and the hose connecting the throttle body to the air cleaner and the air cleaner box for cracks. You can also clean the MASS air sensor w/ tuner cleaner (but only when it's cold AND a soft spray). Check the bands around the air intake to the throttle body on both sides. Erase the codes and see if they come back or if the idle changes. I might take a couple of drive cycles before the lite stays out.
