Hey everyone, first post here!
I have a 2005 hatch with the 2.3l engine and manual transmission. For the last few months, I've been playing parts-darts trying to improve the MPG of my car. When I bought it last year, I was getting close to the 22/29 factory rating. Since around last winter though, I've only been able to get about 18/25 at best. Is this somehow normal for a car of this age, or am I right in trying to fix it?
So far, I've tried...
>New ignition coils
>New spark plugs
>Compression test (all 4@185psi)
>Cleaning the MAP sensor
>Cleaning the fuel injectors
>Upping my tire pressure
>Not driving like a child
The engine has been well maintained, has only 130k miles, and still has plenty of power. The only thing I will say is that twice now I've gotten a check engine light for a random misfire. It never feels like its misfiring, and after clearing the code it stays gone for months.
I'm really hoping this is a common problem, as it seems like MPG is a common topic around here. I'm getting to my wits end with this car, and would really hate to have to sell it. I'm kinda sick of just dumping in money though. Any feedback is appreciated!
