Do you have an insurance device on the OBD connector? Have you had the codes read?

This car has only gave me problems once before... The accelerator pedal wire had come off... I've wrench a lot on my own cars growing up and I'm actually changing the crankshaft out on my S10 Blazer this week... Just pulled the motor yesterday... I guess you could say im a backyard mechanic.. Learned from my father whom had a shop 20 years ago but never got licensed

Have it checked for codes.

I suspect you will have a P1516, which is likely a a throttle body going bad.

Let me know the codes and I will advise further
