do you have an automatic transmission?

 

i do have an automatic transmission. but that doesn't explain why it tops at 105. im comparing my cars performance to how it was before the intake.

 

it makes a huge difference in diagnosing the car though.

If you want help you have to answer some questions man, we can't figure it out for you without your help.

fuel cut would be noticeable because when you got to 105 the engine would stop producing power and you would decelerate, and then pick back up and do it over again.

how many miles do you have on the car? have you checked your tranny fluid yet? does it shift as smoothly as it has in the past?

did you put the filter too far on the intake pipe? is the MAF blocked?

There are millions of questions I can ask to diagnose a problem. it makes it really hard when you aren't standing next to someone though, because you don't know the answers fast enough. I asked a ton of questions so it's easier for us to ask the next set of questions, or to point you in the right direction. the faster you answer them, the faster we can help. if you don't answer them at all you can't be helped at all.

questions that need to be answered to help you move forward are in red.

 

you have an '06, you are having problems above 4500 RPM, and sometimes the car pulls well and sometimes it doesn't.

You don't have enough oil in the car for the oil pressure sensor to trip the oil sender at the camshaft. this is how mivec operates, and if the TSB was correct your mivec switches at 4500. check you oil before you damage your engine, and if it's fine then you need to go to the dealer because something is wrong with the sensor or the sender.

good luck

 

ok first. i have about 11000 miles on it. and no i havent checked any fluids. my dealer has a schedule on when i need to bring it in. every few thousand miles i bring it in to get the oil changed and crap. i dont know anything about the tranny fluid.

second. there's nothing wrong with my filter and its placement as far as i know. in fact i think my intake is a lot better secure than most other chopped airbox intakes on here.

thanks. the oil was just changed today and i dunno if it was low yesterday. but right now i know its at a good level. so we'll see how things go.

 

you should be checking fluid levels every gas fill up or two.

what was the DTC you had set? or have you not had it pulled? believe it or not that will tell you immediately WHY your car is not performing, maybe not what you need to fix but definitely what is causing the problem, if you know what I am trying to say. autozone will do this for free, if you have one around there.

 

what is DTC and what does it do? and im pretty sure i havent had it pulled. lol..

 

Just a guess--Diagnostic Trouble Code.

 

yeah, sorry. diagnostic trouble code. what was it, you said you had a CEL? how did the oil change help?

 

haven't noticed any difference yet. i dont know when im gonna have the time and room to max out.

but what will pulling the dtc do? and is that a must?

 

I remember on december and january when the temps went down in PR in the nights the cel lights up every other day about 50miles diference and as the temps go up the cel stop comming on I think the car was lean because of my cai .It happened when I got the car from the dealer and a week later I put back the injen cai ! with the stock intake no cel. now temps are hot and no cel at all !check if the mivec is engaging as it normaly should and if its conected!

 

I have lot's of breathing mods, and my stock tune is still rich. you are going to have to have the code pulled to show us that it's too lean. I don't believe it, sorry.

yes, car852, it is a must. When the CEL light comes on it is telling you that the ECU has a problem, and it stored a Diagnostic Trouble Code for your review. The DTC will tell you what system, and maybe what part, is malfunctioning.

to be honest with you, if you don't know what a DTC is then you should never have started hacking your stock airbox. You were unprepared for the challenge that comes with working on your vehicle, and may have caused an actual problem with you car

 

Be sure that intake is installed correct and the MAF is cleaned or not tampered with. Also be sure the intake is installed correctly because i had the inner part or watever its called fall off and i had to glue it back on. Even if u had an auto... ur ralliart should not top out at 105 but more like 120.

 

thanks.

and it tops out past 130.

 

drag limited at 136, according to what I have read. hard to get there though, at least for now
