Engine Codes
 

I got my engine codes checked out and here they are

1. 34 ISC Solenoid Valve Circuit Problem
2.Split Air Solenoid or Circuit
3.058 dunno what it is
4.Air Pump Relay

If anyone can help me out are these major issues?

Is the car an automatic? Have you check the components listed?

No its manual, where would these be located?

One more thing if my car is turning over slow should i replace the spark plugs?

Check the battery first and make sure it has a full charge.
