Skipping very hard and son't hardly pull up hill

The cam and crank sensors have the same power wire. Go after that one. They also have the same ground, but other sensors connect to it also. So it's not the ground. And they have separate return signal wires. Not them either.

COULD BE PLUGS OR COILS

It sounds like the catalytic converter could be clogged up.

Drive shaft may be loose at differential.Just solved one of these the other day.Could alsoo be worn u-joints. don-ohio

when ever you have to unhook battery the computer has to learn the engine all over again ,how much fuel ,how much air u get the picture -i believe u have bad oxygen sensors that are bad & maybe something else could be wrong thats why runs rough - cutting off maybe have a diagnose test done on it

vacuum leak in the intake manifold.leaking injectors seals or bad stop up fuel injectors.stop up fuel filter.bad plugs and wires.ignition timing off.weak spark from ignition.and low compression.

is this skip like a miss does it run rough at an idle try changing the plugs and wires cap and rotor and see if this helps also run a good fuel system treatment through the vehicles intake and gas tank and clean it out could have a lot of carbon build up in the engine this usually helps with performance issues.

when's The last Time you got A Tune up??? It's Every 3,000 Miles Or every 3 Months. My car was doing that and i got a tune up ( Change The spark plugs, Oil Change, Change Filter.) And Now My cars Not skipping, it skipped even when my foot was on the brake...

SOUNDS LIKE A TRANSMISSION VACUM MODULATOR,THET ARE CHEAP,MAKE SURE VACUM LINE DOESN'T HAVE ANY HOLES OR DRYROTTED AND YOU HAVE VACUM

Howdy,
the rattling sounds like its the hydrolic lifters (tappets or cam followers called also) not really a hard job just a pain cause you've to strip the engine to pieces to do. Its very time consuming so unless you've some experience i'd place this in the hands of an experienced mechanic. This should also stop the smoke problem.

The engine service light is on a timer from service to service so thats nothing to do with it.

The cd player your right about it just need the lazer llens cleaned. You can buy a cd cleaner kit for cheap in any music/record store.

Hope this helps if not let me know and I'll try and find the solution

Cheers
