K I havent been on the highway in a while. And sunday I went for a ride...in overdrive and as soon as I hit about 65mph at about 3000 rms or whatnot, it didnt go any faster and the rpm's kinda went lower and then back up to 3000 again.Keep in mind I WAS on the gas lol. I thought maybe my cat was clogged up or something.. or maybe my headers just suck???

It's very possible. When I first bought my car, it had a clogged cat. I could barely get it to go anywhere. I left it sit for about a month or two, just randomly starting it up.. then one day I decided to drive it and it would barely move. I could get it to do maybe 40 MPH.. 3000 was about as high as RPM as I got to too. DO NOT take it to the dealership and let them install a factory one. I ended up having to pay 650 dollars for a new cat converter. I could have just got a high flow cat and saved myself money. Just some advice.

No aftermarket headers or anything except a p.o.s. 3A racing muffler. I drive the car every day just not on the highway. Btw..what is the TPS anyway??
Edit.. Ok its the Throttle Position Sensor. How do you fix it and how would it be busted?
Edit 2.. On the way back I took it out of overdrive and it was fine. I was doing about 72 and it was at 4000 rpms. Id much rather do 110 in overdrive though.

You take off the old TPS and replace it with a new one MFR'd by Keifco.
Takes about 4 minutes to do.
If your car is still under warranty (LOL), it's free. The Dae Sung TPS's have a tendancy to go bad. Do a search for "TPS".

Check out that tps first. (I just replaced mine yesterday....worked out good.)
If that doesn't solve your problem check the cat farthest from the engine for a clog. I also had that happen to me before and experienced problems sorta like yours. Its fairly inexpensive to replace. I got a high flow installed from a shop for around $100.

Stick it in neutral. Rev it up slowely...does it still have the same problem climbing in rpm's? Rev it up fast--any issues? When it starts to have issues do you hear any difference in the exuast sound?
Not that this little story will help but I had a peice of cat come off and drove a couple of days like that having issues accelerating. Till one day I got tired of someone tailgating me while I was accelerating so let go of the gas, then punched it to the floor. That peice dislogged, shot out of my exaust with a loud bang, and hit the car tailgating me (straight through mufflers are fun!!!). He stopped tailgating me. Don't thing he ever understood exactly what had happened.

Go to dealer and ask them if your TPS is still under warranty, tell them you know the Dae Sung TPS is known to go bad on our cars and you want it replaced. Let them know that YOU know what you're talking about... I suggest you talk to them without letting them see your car first. Have them agree to change it before seeing your car
