Alright so after a few weeks of troubleshooting, me and a few other friends gave up and took my car (90 civic dx) to our local mechanic to find out what was going on. So when I got my car back the guy tells me he got 5 codes that popped up.

07 - Throttle Angle Sensor or Circuit
10 - Intake Air Temp (TA) Sensor/Circuit
14 - Electronic Air Control Valve Circuit
15 - Ignition Output Signal Circuit
16 - Fuel Injector Problem

Yup, that's about it. Now for my question....

If I fix this car up, anyone have an idea of how much this could run me?
