won't stay running on 1990 Chrysler New Yorker

This might seem like a stupid question to some, but I've got a 1990 new yorker that won't stay running. If I keep my foot on the gas peddle to keep the idle up it will run but as soon as I let up it dies and I have to jump it to start it and it does the same thing.

it could be many things. This car needs to have the charging system inspected if you have to keep jumping it. The Battery/Alternator system may be the whole culprit but this needs to be repaired before you can worry about anything else.

You have low fuel pressure or a vacuum line holed or off. Look for reason for low vac. EGR is suspect.

I had this same problem. I got a new battery and changed the wires. I gave it a tune up.

check idle control module, if you have one. I had the same problem with my 1998 Regal. I replaced the idle control module and problem was solved... on to the NEXT problem(s)! SMH. Coolant Leak and SES Light AND Security Light on... no wonder I'm a Chevy lover.
