I've been dealing with this car for what seems like the entire summer and I have made little to no progress.

Here are the symptoms:

• rough idle
• sounds like a miss
• gas smell
• loss of power
• low idle and near stall condition

I've replaced

• Plugs
• 1 coil that was throwing a code
• IAT sensor
• Coolant temp sensor
• MAF sensor
• Throttle Body
• Fuel Filter
• Fuel Injectors

The wiring harness was replaced prior to me receiving the car.

I get codes that relate to low voltage at ecu, misfire on coil 2 (brand new coil), and then the codes for not having things plugged in. The only code that is really consistent is low voltage code, but the OVP relay is updated to the newer style.

Any suggestions?
