Slow Accleration and Low Gas Mileage Recently, I've been getting slower acceleration and lower gas mileage.. I only have about 24,000 Miles on my 02 Civic...and I don't know what is causing this. I don't know much about cars, but I do get my oil changes done every 5,000 miles... What things can contribute to this....Fuel Injectors, Bad Sparkplugs.? At 16,000 i accidentally had put diesel in my car..but I got it fixed immediately...Does the fact that I put diesel earlier have an effect on the way my car is performing right now?
This Monday I AM planning to go to the Honda Dealer and hopefully get it fixed under warranty. I have never done any warranty work before, so I'm Hoping they will cover this...
..I only have 24,000 miles on this car with 2 yrs of ownership..and acceleration doesn't seem to be as strong..it's just sorta stiff and doesn't punch as much...and gas mileage seems to be lower....Are these problems covered by Warranty... and what would they do on my car to clear up the problems....?

Rep Power: 313 many things can contribute, driving conditions, driving style, what type of mileage are you getting? I think it's too early for the spark plug/injectors problem.....

Check the plugs. Mine were bad at 18K. Also drain and refill the tranny fluid if you have an auto. The diesel may be the cause unless they replaced every part of the fuel system when they fixed it.

Rep Power: 0 I did install new Bosch Platinum-2 Spark Plugs today but the acceleration still seems stiff..and the car just lags......Do I have to replace the transmission Fluid? ...or Could my slow acceleration be due to my fuel injectors...because I DID use Chevron Techron Fuel Injector cleaner to try and clean them up., but My acceleration still feels slow and stiff....The gas pedal doesn't push smoothly like it used to...what is it that I have to replace....?
Do Fuel Injector Cleaner Liquids actually clean the fuel injectors pretty well?....

Rep Power: 787 Sorry, you bought the wrong spark plugs. Should have gone with double platinum (like stock) or iridium. Bosch is terrible. My plugs were dead and I felt a difference getting NGK iridium IX plugs.

Rep Power: 0 if they didn't replace the fuel system after you used diesel, there is probably diesel still reside in the system, diesel doesn't ignite and it needs higher compression, so it's probably not detonating in your cylinder, causing slow speed and bogs
how long ago was the diesel in the engine? and what did they do to treat it?
check was your plugs foul when you removed it, and probably want to bring it in to get it checked. not sure this stuff would be cover under warranty though, it wasn't factory parts that failed, it was a user induced error

Rep Power: 0 if it was that long ago, i don't think the diesel could've been the problem
when did you started to notice this? stiff gas pedal could mean you have some weird vaccume going on inside your intake, check the intake pipes to make sure nothing big got stuck in there, check the throttle from the engine bay, see how difficult it is to snap the throttle
if it's an aftermarket intake, try removing it and put the factory one back in. if it's the factory intake, remove the different parts and what not so see did a small animal or something got inside
does it have trouble starting up? does it idle weird? once you wot, what do you feel? hear any weird stuff?
i am leaning toward something stuck in the intake

Rep Power: 0 I took it to the dealer..and they said there's nothing wrong with the car except that the transmission fluid may be dirty.....

Rep Power: 0 I've just got one question: How do you accidently fuel up with diesel? 
Every gas station that I've been to that sells diesel has the diesel pump away from the regular fuel pumps.
