My 2003 Honda Civic 1.7L 4 cyl has some performance issues?
The symptoms I'm experiencing are sputtering, basically it almost sounds like an 80s vehicle… It idles rough, and the temperature gauge also goes up during idle for an extended period of time… Yes I just had my cooling system topped off. As far as rough idling, it only idles rough. Once I start driving it seems to dissipate and drive like normal. I've gotten several opinions so far. Some say spark plugs, some say fuel filter, some say injectors, or could it possibly be the idle control valve? I'm so confused what it could be. I just want to get to the bottom of this. Anyone have any ideas?
It's almost 15 years old. It's going to have some performance issues. A qualified mechanic can tell you what the problems are.
Did you pull the plugs out and see what they look like? When was the last time they were changed to start with?
Fix the over heating problem first.

- What are some performance mods I can add to my 09' Honda Civic Si without hurting the lifespan of it too much? I will be commuting 50mi. Each way once college starts this summer so I won't be able to add any sort of turbo/supercharger. I'm planning on getting an intake, throttle body, and headers. Just wondering if I can do anything else besides those listed ^ :)
- Should I buy a 2008 honda civic ex-l that has 100000 miles or a honda civic lx that has 82k miles? The honda civic ex-l has only one owner and the honda civic lx is from a dealer. They're fairly the same price
- What are some affordable modifications I can make to my car to improve performance and maybe spruce the? I have a white1995 Honda Accord Ex wagon with 225 miles in it. It has a few rust spots and requires some basic maintenance, which I'll take care of myself. I'm going to add a cold air intake and am looking for other things I could do to customize my car so it's something I like to drive. I'm not looking to spend big bucks but if there are any good ideas I'm willing to the work? Also I'd like cover up the the white worn out paint.
- My cars (2003 Honda accord EX 4 cyl) RPM is really low when my car is idle and makes my car shake? When driving the RPM will also lock up or drop low randomly and make my car shake, like it doesn't want to go. Yesterday I was on the highway and the RPM was stuck barely above 2,000 when I was going almost 75-80 MPH which is usually at almost 3,000. It felt like my car didn't want to go much faster than that.
