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)?

 

have a check engine light or anything?

 

No check engine, but the maintenance required which I reset already

 

Check your IMRC. I noticed similar symptoms when mine wasn't working

 

did you do the basics, like plugs, Oil.. is it time for that to be changewd yet?

 

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

 

How hot is it in NJ? Humidity?

I know I've lost about 20 whp due to 95 degree weather. And it's the same every summer.

 

You should be able to find that IMRC for about $90-ish. I'd be willing to bet thats the problem. Have you tested it?

 

Mine still feels "fast" in WOT, but I've checked the IMRC, I can never see it flipping over.

 

pull the black plastic engine cover off

 

ok. I'll try

 

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?

 

LOL

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.

 

Wow, that's pretty light.

 

sea foam?

 

Yes the IMRC should be under extended warranty. I had mine replaced under it. First check it yourself before you take it to the dealer, it is really simple.

 

Its not the car its the driver you noob, don't forget I smoked you the other day.

 

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

 

I agree with phipark It realy the weather hot and humid my car is running so slow at the track

 

 

Women love guys with big skippies and you just reminded me I do have to put my brake pedal back on this weekend. Maybe I'll stop by tomorrow

 

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

 

couldn't it be the ethanol in gasoline that's also causing the car to lose a few MPG? or was that just a rumor?

 

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.

 

It very well could be.

 

interestingly i read an article and E85 ethanol is between 100-105 octane i would have thought it was 85 oct as it's name implies

 

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

 

Repito it's the driver not the car...cabezon

 

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.

 

what is the IMRC and how do we check it....

thanks

 

 

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!

 

12-25% less on cars that dont need the higher octane ...i wonder how hi compression engines would respond to the E85?

 

now my IMRC doesnt work at all at any RPM I used a voltmeter to try and check for something from the plug on the IMRC but got nothing. is my pcm fucked or is there no ground on that plug for me to get a reading from? please help

 

85 = 85% ethanol.

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.
