I installed a new alternator and new battery for my rex and it ran fine for a couple days. I still see the check battery light and check oil light on. Plus wen i turn on the car the rpm's keep bouncing up n' down and it eventually make the car die. So wat is the problem with my car? O2 sensor? something electrical or fuel?

 

Check your wiring. Did you even check the oil?

Sounds like bad wiring.

Changing your battery does NOTHING TO THE PERFORMACE OF THE CAR OR RELIABILITY, except for the first 5 seconds when you crank the engine over.

 

oil is good and this motor is a ZC and i bought it swapped. Its running on a pr4 ecu atm. So it might be wiring issue?

 

first things first- when was your last tune-up? Also, double and triple check the connections on the battery- make sure that they are tight, and completely free of corrosion.

 

Im thinking its distributor is it common to have hondas distributor go bad?

 

Check the alternator belt tension. It may have loosen. Try tightening it again, and see if it make a difference.

 

honda distributors are notorious for going bad. But usually when they go the car does not start anymore. DIAGNOSIS DIAGNOSIS then repair. Don't waste your money on a 150 dollar new dizzy if that is not your problem. Engines swaps have inherent problems. It may take you a while to figure out a problem like that or you might find one connector or ground loose or corroded causing the whole problem.

 

Back track what you did, double check anything you replaced or touched.
