Code P0130 adn p0133, after installing header and downpipe Options

[msk59]

Hello: After installing the header and getting it all set, I am getting these two codes. I reset them once and these two come back again. I will check for leaks etc and the reading on the first O2 sensor (7aFE engine stock, 1996 ST HB). What else I need to look for?

How do I check for sensor circuit heater?

thanks in advance.

Hello Guys: I am facing a new issue. After I discovered the leak (bad gasket) between the eBay header and the down pipe, I am stuck without a gasket. No one, even the seller does not offer spare gasket for that pipe. I have been pushing him to get me a couple so I can have one spare. So far no luck. He says he does not have spares nor he knows the part number. (This was my worst buying experience).

here is the vendor I purchased from:
http://www.ebay.com/itm/Toyota-Celica-94-9...erformance-Race.

If you look at the bottom, the second smaller gasket is the one I need. The measurements are 5 inches in the center from one side to side; the width is 2.75 inches exactly in the center. The top two holes are approximately 3.75 inches center to center.

O'Reilly guys ordered some but they were smaller. I have found several similar on eBay and one has the measurements (showing ruler on it) that seems to fit and I have ordered it which will be here next week but fitment is not sure at this time.

Any help or input would be appreciated.
