so its is a stock intake with a drop in K@N ifilter? double check your connections on your intake since you took it a part. When did your car starting driving like this? after cleaning the intake? after installing the hi flo cat?

 

Check it all.........oh, and I re-wrote the post above, so you might wanna look at it again......I copied it below in red.
Make sure all clamps are tight. Make sure the MAF O-ring is okay.

Did you break or crack one of the plastic elbows on the accordion when you took hoses loose to take the accordion out, or did you just leave it on during this cleaning?


Are the screen(s) still in the proper places in the intake track and haven't been removed, knocked out of place, or mangled?

 

its ran like this since right after i bought it. the screens in the intake... well the only one i see is ripped to shreeds. ill recheck the connections and where is the Oring exactly??

and to clear it up. everything on this car is stock but the exhaust. its a highflow cat with 2 and 1/2 pipe to a singke chamber flowmaster to a 4 inch tip. thats the only mod done.its just a drop in filter.

would these be recommended?

the mesh screen is ripped?????? that will cause some serious rough idling.

 

i honestly think BHR ignition system is your best bet. they have a good name here in the forum.

 

oh it ildes rough. i didnt know if that had anything to do with this or not.

 

ill look those up too. i mean hell.. might as well get some kinda performance if im gonna spent tha much money.

 

huge reason. It can even cause the car to stall. You should have two wire mesh in your stock setup. each screen makes you lose 1 hp but without them, you will get possible stalling and a horrible idle. My REVi intake only has 1 mesh screen and is fine.

 

i was thinking about gettin an AEM cai

 

There is a 'velocity stack' curved lip piece inside the top of the air cleaner - make sure it's in place.

That is also where the thin wire screen should be, the lip holds it in - if there isn't one (or it's torn (bringing up the question of wtf went thru there?)) get a new one, you need it to straighten out the air for the MAF to read correctly.

Clean the MAF. Properly, not just a squirt and a shake.

Pull some code numbers before you post again - we don't like guessing games....

I love my REVi intake with ram air but I heard the AEM is pretty good. You will have to use the stock screens though.

 

well damn. cant use them if i dont have them. haha. ill go lookin under the hood tomorrow. post the code. and see exactly what i can do for all this bullshit.

 

ok so the code WAS -EVAP emission control system leak, very small-. the code went off friday when i took the airbox apart and checked the elbows on the accordion pipe. there is one screen still in the intake. its the rear one closest to the engine. the other is torn to crap. strangely enough, today the tire pressure light went off also. but im still having that jumpin and jerking going on.

 

evap leak is most likely from a loose gas cap after a fillup.

 

Get a new gas cap for the evap code.

 

dumb question but what do you have your tire pressure set at?

 

left front- 31
left rear- 30
right front- 29
right rear- 31
that light has been going on and off.
still havent got the plug wires in yet. but as soon as i do ill figure it all out and if its not that its gotta be the coils.

 

When it comes on.............is it solid or flashing?

Solid......tire is low(below ~26 psi, or it will even go off on the high end at about 50 psi).
Flashing.......TPMS issue itself, most likely battery in the TPMS itself.

You check your tire pressure with more than one gauge? Maybe gauge is off?
If stock tires, you should be running about 32-34psi in each. Might wanna bring them up a pinch.

 

yeah its solid, for days sometimes.

 

If you read 29 psi and this was with the tire warmed up........AND...........when it was solid it was either on cold tires, OR your trips were not very far, then I think you might be below the threshold. Put some air in and see what happens....can't hurt.


If it works....at least you will feel like your making progress and can then get back to the real issue at hand.

 

will do. which coils would you recommend Mazurfer??

 

I am not an expert by any means.
If you want stock coils, then just find the cheapest place. Don't get them at the dealer, look on here and you can get them fairly cheap. This is but one of many places to get them.

If it was me......and I had the money, I would go for the BHR kit hands down. http://blackhaloracing.com/products-...tion-system24/

 

i know you say youre not an expert.. but whats the real difference??

 

It's a disclaimer...so you can't hold me responsible for anything I might say.


To be honest, I was never into cars that much until this one. So I only got a little bit of time under my belt.

Used to attempt to fix and learn things on my past cars only when something went bad. Kept up on basic maintenance, but that was about it.
