Please elaborate on what you define as "running rough". It takes a lot to make a civic junkable.
- Are you the original owner?
- Have you performed regular maintenance? If your 10 year old Honda is running that poorly then I'm inclined to believe it hasnt.
- Are there any leaks? Do you have to regularly add oil? Have you even checked all the fluids?
- Is the engine making any loud or obvious unnatural sounds, such as ticking, tapping, metal-on-metal screeching, etc.?
- Do you have excessive smoke or fluid in the exhaust?
- Do you constantly smell burning oil, gas, or anything else?
- Does it struggle to accelerate and/or sputters while accelerating?
- Does the ignition turn over alright? Does it hesitate heavily to start?
- Does the idle fluctuate?
