So for the past few weeks if been noticing an odd problem that started when i got the car back from my mom, and sometimes (usuallyafter i drive the car for more than 25 minutes and go about 20 or so miles) the car will idle at a higher RPM than normal. Im not sure exactly what the RPMs are at because i fooled with the gauges a while ago but its pretty close to 1000 or 1300RPM when i stop at a red light or put the car in park,the tib just sounds different, like in park it just sounds like im reving it a bit and the problem dosnt go away unless i take teh key out and start it. i have 90,000+ miles and i just did an oil change last week. HELP

 

could be two things. Air leak or a bad TPS

 

i had same problem before.
bad TPS

(check if your TPS is Daesung. if it is, change it to Kefico, and it'll be fine)

 

quick question, whats a TPS?

 

Throttle Position Sensor. It's on the side of your throttle body. Hyundai has to replace it free if you have the DaeSung.

 

Alright thanks everybody, i actually looked it up after i asked, im not too bright. And i started to read up on different engine mods.

I'v never really been interested in turbos and superchargers due to problems that people encure as well as other things, so iv been wanting to get into N/A mods, and this summer ill be looking to spend some money as well as help prolong the life of my tib, so im looking into replacing some engine parts and well i guess what im trying to get at is that i want to replace:

CAI, Big Bore Throttle Body, Intake Manifold, and headers through to (possibly) custom dual exhaust.

I know i want the AEM CAI just cause of the name and quality.

Iv been looking at Big Bore Throttle bodies but i just dont know how big i should go or what company is the best to buy from(so far i only know of R Side, i know it all depends on the price im willing to spend and i dont want to buy crap any more so if i have to spend a couple hundred then ok, as long as it stays on and dosnt crap out)

Iv read some on the AirRam intake manifold, and the only thing im afraid of is that the inlet size will not match the Big Bore Throttle Body size, are there any TB+intake monifolds out there that work great together? also how easy would this be to replace, would there be problems with having too much air forced intot eh cylinders with just the same amount of gas (you may notice im not sure of what im talking about so any help would be great).

And exhaust, i need something that will still pass inspection(meaning has two O2 Sensor openings and 2 cats) and not sound incredibly geh (as my SSA header back sounds now) Should i get a 4-2-1 or a 4-1 header?Oh and whats this MBRP exhaust i see tibbychick used to have and others have? where can i get it from, iv been looking all over?


any help would be greatly appreciated

 

Now that's what I'm talking about. Good questions.

You've been searching.


Let me answer a few things.

1. ONly way you can get an Rside is used, they went out of business about a year ago.

2. The best to get these days would be the Tigerilly 65MM BBTB.

3. The airram IM opening is 68MM, as long as your TB is that size or smaller, you are fine. Therefore, the 65MM will work great with it. Especially for high RPM N/A and small to mid size turbo or SC.

I've got a 58MM Tigerlilly BBTB I'll be selling shortly, for right around 190. Let me know if you want it.

Headers.

Some point certain headers towards certain transmissions, I just say get the best ones out there. Right now that would be the Maintec GT Headers or a step down to the Maintec Racing headers. Pricey, but VERY good in quality and performance.

4.2.1 or 4.1, it's up to you. The 4.2.1 will have higher gains in the entire band I belive, but the 4.1 will have a bit higher than the 4.2.1's in the upper RPM band. Personally, I say go for the 4.2.1's, they are easier to find and give a more constant result.

Soon there may be an offering from Hotshot for a cheaper price. They make very good stuff, but are being pretty slow about it. We'll see how that goes.


Exhausts.

MBRP no longer makes exhausts for us. You can only find one used.

I'd say you should pick up a Moteria catback from Importshark.com or the ARK Catback. Both are very good quality, both have very good performance and sound characteristics.

 

WOW ..... what happened! Did this thread change of what?

It's the throttle sensor ....... $180.00 at the dealer.

 

yea i know its just the sensor but iv been looking to add some nice mods....


OK so i was looking at the airram intake manifold and i noticed that it says you need a 2.0 tiburon and i have a 1.8 so im assuming i can no longer get that, with that knowledge, should i still go ahead and get a new TB and the Maintec headers with a HKS axle back along with the AEM CAI?

or should i just replace the sensor and not worry about engine, just focus on astetics?

 

The 1.8 and 2.0 both use the same head. There is no reason the Airram would not work on a 1.8.
