What to replace when MPG is bad and the car is feeling sluggish
I know it could be the change of weather, but the car started to feel sluggish, especially when getting into the HWY under WOT, it's just not what is used to be. It's also consuming more gas than normal. I started by replacing my CAI filter, that thing was terrible, I never cleaned it in 3 years, bought new spark plugs, what else should I replace/check (fuel filter, any sensors)?

Moodist & agranado, Yea, im actually changing all that stuff this weekend; plugs, oil/oil filter, radiator flush, ac filters and see how that goes before I go and replace the IMRC, that's a $125 part. Just wanted to know if there is anything else I need to replace other than what's mentioned that would make the car feel sluggish

Jersey weather is at about 85+ but the humidity is terrible due to some recent rain. Also last oil change, I know for a fact the place I went to used X brand oil, filter doesn't even have a name on it, it started to feel this way 2 weeks ago right after the oil change too, the air filter was really bad also, I will get an oil change with good oil/filter, install/change my plugs other fluids and test my IMRC Thanks guys

Stop flooring it when you're driving. 
On top of the heat and humidity, remember that your new shoes are probably not as light as your stock ones. And shouldn't your IMRC still be covered with your warranty? How many miles are you at right now?
I can't think of anything other than the air filter and the plugs. What about servicing the fuel injection system?

well the new wheels are only about 19-22lbs with the tires so I don't think that would be the issue.
I was wondering if the IMRC would be under warrantee, I made an appointment with the dealer, Im at 60k, I have extended warrantee

I was just thinking about this... I used Lucas Fuel Injector cleaner in mine awhile back when she was feeling sluggish. That made a huge difference. The guy at the parts store recomended it to me. I'm glad I used that instead of Gumout or something. That Lucas stuff is the shit! It's WAY better than anything else I have used.

Thanks fellas!
I will check the IMRC and add the Lucas Fuel Injector cleaner to my list
LMAO yea ok Ray, caught me off guard, I was looking at my cheese burger while you floored it, that's why we had to go buy new screws for your mugen gas pedal, ripped off the pedal with those big skippies you had on

Well I used the awful search button that everyone always tells somebody to use. I searched imrc and IMRC and got nutin. So heres the ? Can someone please post detailed instructions on how to identify and check it? Im 95% convinced that anything on my car that is made out of metal has been issued. I think its because its from Maryland. I dont know. Ive been replacing and cleaning everything. Sometimes I wonder if by the time I done, if it would have been cheaper to build this bitch from scratch one piece at a time. Thanks

I just installed the thermoblock spacers and the intake was horrid. under the aluminum manifold cover was all kinds of carbon and oil deposits. my car has 75000 miles on it and i had to pick most of it out with a coat hanger. I disassembled the entire upper intake manifold and it was disgusting. the car runs much better now. I highly recomend you really clean this part if you have more than 50000 miles. my car runs much smother now.

your IMRC could be failing and is most likely the culprit. It could be the vtec if your speedometer is acting up. it could also be the primary o2 sensor. good luck. pm me if you have any questions.

Hess gas has like 10% ethanol in it and I have been using allot of that gas lately, hmmm
I cleaned the intake manifold and throttle body when I installed the thermblok spacers last year.
After changing the plugs, CAI filter oil, and fuel injector cleaner, there was an improvement, but slightly, tested the IMRC and it looks good, I’m thinking this may be a CAT issue, , is not that bad now though, it's probably starting to go bad, I thought CAT's last over 100K miles, I only have about 60k right now

All the reports I have read show anywhere from 12-25% worse gas mileage on the new "ethanol" mixes. It's supposed to be "cleaner" and make us more reliant on our own energy sources. So who foots the bill?? Of course the consumer!! Higher pump prices and crappier MPG until engine design starts taking better advantage of it. All the while the oil companies post record profits. (Note, I said profits, not just income based on the price of oil.) Anyway, in short, no it is not a rumor. It is worse MPG.

If its not a Type-S then there is no IMRC. Definitely replace the air filter!! I just bought mine and it was from an Acura dealer that said it was "certified". Yeah, well their "inspection" must suck! I assumed the air filter was fine but when I checked it while changing my oil today, it was terrible!! Replaced it and the car is driving much smoother and more responsive!

Hi octane, yes - less likely to knock, but also lower energy density - poorer mileage.
From what I've been reading, this stuff is really a bad deal for the environment, and just a fancy farm subsidy.
