The car has been making a squeak when I turn it over for a while but hasn’t struggled starting until the other day the revs just bounced under 1k and it shut off tried a few times, one time it started badly then just died. Eventually got it going. Any idea of what’s wrong with it? I’ve tested the battery and it’s okay & changed the spark plugs.

It’s starting first time (most the time) now but still has the squeak/ squeal when starting.

Hi.

Is it spinning over ok..?

The fact it shut off isnt great

As a 1st step..
Disconnect battery overnight...( charge if you can..)

Then reconnect and see how it is..
This willl restore factory ECU settings

Any news??
