I just checked my car & I have 3 SES codes stored.
I have code 26 which I know is a quad driver circuit,

then a code 34 something about the mass air flow, which i just replaced, but is still on

also a code 63 exhaust gas recirculation flow check????

Anyone have a clue on how to try & fix these?

Plus the car is hard to start. I have to try & start the car 3 or 4 times to get it to start. But after I drive it for a while & stop for a few minutes then go it will start right up with no problems.

Oh yeah the car is a 1989 Bonneville SE
