2005 GT Failed Texas State Inspection

MexGT · 07-22-2008

switching to the stock tune with the stock airbox is no problem, just for inspection.

CRico · 07-22-2008

Hi guys,

I just had my state inspection done and I failed. The things that I failed on are: Catalyst: Not ready, O2 Sens: Not ready and finaly O2 Sens Htr: Not ready.

The tech said maybe my computer wasn't programmed. Wouldn't that mean the car wouldn't run? He also stated that I should disconnect my battey and reset my computer. The question is that I have a few mods and am wondering if I have to go completly stock durring the "relearning" stage. He said it would take about a day of normal driving for the computer to get back to normal. Problem is I have to go back to work in a few which is 200 miles of highway driving. Will that be considered normal driving?

This is the first place I came when I was told of the problem. You guys always have the answers.

BTW the mods I have are: JTL2 CAI W/SCT Tune and Slp loudmouths (the straight pipes)

Any help in this matter would be GREATLY appriciated!!!

Thanks in advance!!

You should disconnect you battery. Do you have any type of muffling device do you have you cats? I'm in west Texas and just passed!!!

Agree that you should return to stock. If you don't, the O2 sensors are going to continue to be a problem.

If you get the 'not ready' error refer to the following:
ALL MONITOR DRIVE TRACE

I hear you! No tests here either (fingers are crossed).

crzyhorse11 · 07-22-2008

yeah here in Texas its relatively easy to pass as long as you have cats and some type of muffler however if your check engine light is on you will not pass nor your gas cap light. also you cant have any kind of leak in your exhaust or vacuum hoses. Texas is pretty simple

**stlwagon** · 07-22-2008

Most states use the OBDII readiness check (for post 1996 vehicles). Most will permit a number of failures/not ready conditions before failing.

CRico · 07-22-2008

I had no fault lights or check engine light. The only thing I can think of is that I had a satalite radio installed around father's day. I'm pretty sure they disconnected the battery. If there anyway to check to see if the problem is corrected once disconnecting the battery? I guess I can dig up the stock air box and go that route, but I was in a hurry to get back to my second home (which is 200 miles away) and didn't grab it. I guess I'm wondering if there is a different route other than going back to stock (which isn't that hard with the few mods I have.) Would the SLP's alone cause the fault? I was under the impression that the cats were further up the exhaust towards the engine.

Also on the SLP's, there are no mufflers, just straight pipes from the center pipes (which is all stock up to the engine)

Just seems a little odd that I wouldn't get any fault codes or check engine light.

Thanks for all the input so far!! You guys are great!!!

Good info! Forgot to mention my GT is an auto....

Most of it I can follow, but unfortantly I am not gifted in the repair of cars.

Fixing airplanes I can deal with

That is seriously scary

You cannot pass because you need a muffling device and catalytic converters to pass TX inspection. That is unless you can find someone to slip 20 OR some one who wont check. By muffling device I mean any kind of muffler (flowmaster,magnaflow,spintech, glass packs) you have to have some type of these. Also the exhaust must be exiting out from under the car via side or rear pipes (no dumps). Your car must also have the original number of mufflers and cats. So maybe that is it. I know its a lot easier when you know someone!!! Still not as gay as California but they are strict about exhaust now days. Lets me know if that helps you, if not just ask em next time exactly why they wouldn't pass you and how to fix it and they should tell you.

However if it is only your O2 sensors they have a code for get an MIL inhibitor. They may possibly in the wrong place or in a midpipe sometimes not connected. Either that or its switch back to stock.

GOOD LUCK

Thanks buddy for the info. I was under the impression that the SLP's were 50 state emission legal. I guess just to be on the safe side, I will install my stock air box, put back thouse 50 pound weights on the back and return it back to the stock tune. I'm not sure that "tipping" the inspector will work, since all of the checks were done through the computer and would make sense to me that it has a bare minimum amout of thing to check automaticaly, like a diagnositc program. I guess I'll be under the car on my weekend off and hopefully have it ready the next day. And BTW since you are from TX will my sticker be good for longer than a year. I have no idea the rules here since I have just came out of the service and spent 14 years overseas.

Thanks again for the input!!!
