Battery wont hold charge - 1993 Jeep Grand Cherokee

doesnt hold a charge is not a good battery --have battery and alternator tested

If you have to remove the PCV to get it to run, it's starving for air. Most likely a bad idle air control valve. Battery wont hold charge is a separate issue. Get your charging system tested

Check the water level in your battery cells. Low levels wont let it hold a Charge. . .

how old is the battery

You most likely need a new one it happened to me many times you drain it so bad that it wont hold a charge anymore.

take it back they have to replace it,they either have a 60-90 day warrenty also see if battery cables are tight.if you have a chrger see if battery holds a charge.

You may have a bad alternator... you can have it checked at any auto store for free... Also check your positive/negative wired connections...your connection to your positive cable that goes to your starter may need to be replaced, or your negative cable could be bad also.

Take it to Sears or another large auto parts store and have them test the condition of the battery. They do the testing for free!

that sounds like your battery... do you have an alarm or amplifire not running off your accessories? or could be a faulty battery

check for battery voltage at the charge post on the alternator and at the 2 wire connect with the key on .if you have it then its a bad alternator. if you have a belt spinning the alternator.
