no.. I am actually testing the tps and wiring.. but I dont really know what is the problem with my xj, its a 99 automatic, but it suddenly started shift very late making me waste alot of gasoline and does the same thing with reverse... late shifting, very late shifting, does not stall but them rpms goes to 1500 without even accelerating when I barely turn on the engine. and while driving it takes for ever to move, rpms have to go really high in order to shift.. and sometimes it would go to neutral stat even though its on first gear or any other gear.. its really frustrating.
