I have Cadillac Catera 2000. The "Check Engine" light is always ON. the diagnostic shows errors 300, 302, 304, 306. what is the problem with my engine and how it could be solved?
What have you done so far. I would start with looking at the cars repair/maintenance history. Have the codes read (might be helpful). Could be anything, depending in what direction you need to go you might want to check for cyl. miss-fires, bad coil, IAC, fuel pressure, clogged CAT. CMP sensor. Let me know if I can help anymore.
