Chugging?

Would a bad cat through a code though? I mean, it's pretty bad.

My car didn't show any codes.

To check you could pull your front o2 sensor out and see if it runs better

I found this thread so I thought I would ask about this too.. My car seem to pulsate on the RPM's around 2000rpm. It will go up and down by about 200-300 rpm's. This will happen on light acceerationas well. If I hit the gas it will go away. Mine seems to do it more when its cold.( I think) I also noticed it when I had all of my work done on the LIM gasket and UIM replacement. They put all new seals in including the throttle body gasket and the MAF sensor I think.. I have been wondering on what is causing this.

I have all new O2 sensors so thats not ti

Anyone? I haven't tried disconnecting the battery yet.. are those pars in the trans expensive to replace?

Clean the TB, do a tune up if it hasn't been done recently. Igniton is usually the most common item to cause this.

Just brought the car into the shop today... Waiting to hear back to find out what it was..

Any update

Nope... Just waiting on them to tell me what's wrong...

So I took my car to two different mechanics..... Neither one of them can find out what's wrong... They definitely can tell a loss of engine power but can't figure out what is causing it. I'm stuck...

Update: Cleaned the tb... Still nothing... Still runs like shiot.

dirty tb

video of it.... it feels worse than it looks

The video seems normal to me i didn't see anything abnormal.

It just seems a little sluggish for wot... When I'm under light acceleration it's a lot worse.

Also, could a bad fuel filter cause these symptoms?

Ok, so I just pulled the TCC fuse and the car ran like 50x worse... So does that mean it's not the TCC?

And I just realized there is a large amount of heat coming from below my center console. I can feel it coming through my cup holders.

thats your exhaust pipes, you shiftier cable boot is likely torn up and letting heat in the car. the cat is pretty much in line with the middle of the console too.

I've never felt it that hot before.... Like it was blazing... I took out that little cubby like thing near the front of the console and put my hand down there and i'm pretty sure i burnt my fingers.

look under the car after its been running for a while at night in the dark, if its glowing red its shot/clogged up.

I looked... but where my car was parked I couldnt really see all that well but I stuck my hand just to feel how much heat it was giving off and it was very hot... Is there any way except a back pressure tester that you can tell if it is the cat?
