After installing a short ram intake on my 00 TL, it wont pass a certain rpm. At first, it would only rev to 3k and stutter and stay at 3 k going no further. After turning off and turning on again, it stutters at 5k, going no further. On the freeway, as soon as it hits 5k rpm it drops. I've also cleaned the throttle body when i installed, using throttle body cleaner. What might be the problem here? I also got check engine light, which has disappeared as of now when i plugged out the backup clock fuse.

This goes a bit more detailed to show how it goes. If it helps at all

 

i think you should check your throttle body. make sure that all the connections are secure and correct. intake sounds bad ass tho!! love the sound of vtec. keep it up.

 

Hmmm...well i never had this problem. But then again i had a shop do mine & i had exhaust installed (which may i add, sounds awesome !, you should get it too). But i think your ECU sense that it's taking in more/less air than stock so it's stopping you from reaching 6k(limp mode). i would recommend to reset your ECU and see how it goes

 

That's supposed to happen, you're in park.

 

rpms drop after i reach 5k on freeway, so its not just a park thing.

 

So are your lines connected to your intake correctly? Cuz it sounds like a vacuum leak maybe.

 

i can hit the rev limiter when i'm in park.

 

you say you cleaned the throttle body earlier, did you take the throttle body off? or did you clean it while it's still connected to the intake manifold? if that's the case, did you possibly not torque the connections right? (18 ft./lbs if i remember correctly)

 

I didnt take the throttle body out, i just put a rag under and sprayed it with throttle body cleaner then used a toothbrush to get in there, and then i wiped it down good with a rag.

 

Go out and make sure EVERY thing is plugged in. Installation of the CAI shouldn't cause this. something got disconnected. Did you unplug anything? or any hoses?

 

my limiter is around 5K in park. was this before or after your 6 speed swap? although MTs dont have a park gear...

 

dude i was watchin the vid again and i heard some one call your car a rice rocket? wtf is up with that. acuras are NOT rice rockets. acuras are performance luxury vehicles. dont listen to anything he saids. keep up the good work. what car does your friend drive?

 

this is with both stock ecu and type s ecu. i'm still running stock engine till the end of this week.

 

still unable to figure it out. anyone know how to reset ECU.

 

and how to check for possible leaks that i cannot seem to see.

 

soapy water

 

Testing for vac leaks:
spray carb cleaner at hose connections and tb to manifold- air flow tube to tb.
if rpm changes you found the point of leak

Hooked the pcv sytem into the new cai? other vac lines connected
Ck master vac port presure with vac guage- should be 20+

the clock fuse IS the secret backup power to the ecu and will force a master reset and relearn

are you getting vtec engagement on freeway? the connector for that has gotten left disconnected before

what else did you do at install== any other work?
seafoam?

 

assclown- I have to ask- soapy water is for locating `pressure out leaks` in most uses--how is it finding vac leaks???

I dont want soapy water going into my engine--regardless of its steam cleaning abilties!

 

I would just disconnect everything and start over. It doesn't take long to begin with. Check your hoses while they are off. Get new ones.. They are about 3 bucks or less. Disconnect the battery. Has to be something minor.

 

where exactly is the connector for vtec engagement

 

and seafoam was not done, only cleaned throttle body without taking it out. Pics help ofc of all connections

 

 

Do you have a CEL? If not resetting the ECU will not do any thing. Vtec connector is down by the oil filter. Go back and double check your connections. Make sure they are all connected and that you didnt miss anything. The vac and coolant lines, did you take any off the TB

 

none off the tb, i did disconnect the electronic thing on the top of it while i was cleaning it

 

why don't you just take apart your intake and reinstall again making sure you have done it properly.

 

I was going to suggest a reinstal as well.

How much have you driven it after the instal of the intake?

 

I've driven it maybe 50 miles maybe a bit more, everything runs fine, just wont pass that 5k rpm

 

how about you just take it all apart and reinstall and then see if the problem appears.
