hoping you guys can give me a little help, though i don't have alot of info. on my way to work this morning the "Service Engine Soon" light came on. it is an 02 TA WS6 M6 78000 miles. all vitals (temp., batt., oil press.) on the gauges show to be fine. the car ran fine the whole way to work, it sounded fine and had no problems. i plan on taking her to autozone to see what codes she is throwing. thursday the weld for the emmissions on the third cylinder primary broke off and i had it welded shut till my new headers come in tomorrow (monday) and i pluged the hole of the hose. could this be the reason the light came on? but why would it take 3 days before it threw the code if it is? today was the first cold morning we have had maybe that is why. any help you can give will be appreciated. i wish i had more info for you.

If you still have secondary air and you plug or kink a hose it'll throw a SES light. Post the code when you get it.

ok thanks will do... my new headers are off-road so what do i need to do to delete the emissions lines and such?

ok the code it is throwing is P1133 it said something like "Manufacturer Control Fuel Air Metering"

well it just shut off. any ideas why this may have happened? from a few other threads i have read p1133 relates an o2 sensor, is this correct?

2001NBMZ28

P1133 is insufficient switching, bank 1 (drivers side) sensor 1 (precat) 02 sensor. I'd just wait and see if it comes back. Since you're doing headers you'll be removing/replacing it anyway. You can look up the description/diagnostics at gearchatter.com As for the AIR you can remove all or part of it, www.ls1tech.com/forums/showthread.php?t=673299

I'd go ahead and replace your O2 sensor. The way the PCM throws codes for that is on the second error for that O2 sensor. Thats to rule out false SES lights, do it after your get the exhaust leak situation sorted out though. Your car will run like poo until you get it replaced.

will do what o2 sensor do you suggest?

i see alot of people using vette o2 and some using bosche...

Just get the stock bosche ones. I've heard some people have problems with the Vett O2's not switching properly and throwing codes. Some have the issue some don't, I'd play it safe and get the stock style ones in there.
