I just put a starter and computer on my car. It started right up but it is not running right. It is a 4 cylinder, 2 litre 1994 sunbird. Could it be the oxygen sensor, wires or gas filter or what?Could you please get back to me. Annette Thank You

If it's not running right there may be a service engine light on. If it is you need to get teh engine scanned. Most auto parts stores do this for free. If there are no codes then check the fuel pressure as it may be low. Other than that you'll pobably need to take it to a pro.

How long since overall tune-up? Any applicable codes? Use a gage and check fuel pressure.
