Before i start, i have seen the idle surging checklist. Im not too familiar with the terms used and i just want to know what could have caused this out of nowhere
So i got a 1993 Mustang 5.0 and I've had it for about a month now. I would notice on startup sometimes, the RPM's would jump from 500 to 1500 and then it would die if you don't give it gas. As the RPM's would drop to around 500 the battery guage would slightly drop down too and then back up when the RPM's would hit 1500. While driving the RPM's would be stable at 900 and it would run fine. Yesterday I took it for a spin and coming home it suddenly started surging again while in first gear. As I pulled up to a stop sign i put it in neutral and it kept on surging up and down from 500-1500. As i put it into first gear to leave the stop it dropped really low and the car shut off.. it started back up and while driving home it the RPM's kept jumping up and down wanted to die again if i let off the accelerator.
Why has it started doing this out of nowhere, the car isn't able to drive now since it just dies if i don't give it gas..
