So this happens usually only in the mornings I have yet to see it happen any other time but when I go down for work and start my car sometimes it stalls sometimes It doesn't start right away but when it does start my check engine light turns on and my D4 starts blinking but after driving it for a little bit i will turn it off and turn it back on it goes away and doesn't do it for the rest of the day please help?

 

Pull codes from blue connector by glove box. D4, cel srs and abs will blink respective codes if any when key is turned to ig2 but not run

 

could be dry joints on the main relay under dash drivers side

 

It's most likely an ECU issue. These control units are almost 25 yrs old now and the discrete electronic components (electrolytic capacitors inside with a gel material inside a metal tube) are ether drying out or have swelled and failed.

If you have any soldering skills you can repair this issue fairly cheaply.

Please post an update. Thanks.
