986 dies on startup or idles rough and gas pedal does not work
 

Hello, this is my first major problem with my 01 986. I bought and installed 2 Downstream Bosch smart link o2 sensors and wired them onto the existing post-cat o2 sensor connectors.
When I started up the car it died immediately. After a few tries while holding down the gas pedal, I was able to get it roughly idling on 1000 rpm but now the accelerator pedal does not work. After driving it around the parking on 5 mph, 7 cel codes pop up and they are as follows: p1219, 1578, 0103, 0132, 0152, 0138, 0158. First 2 are accelerator pedal related, p0103 is MAF related and the last 4 are all post and pre cat related. What could have gone wrong to trigger all of these cels and what can I do to fix it? Did someone have this happen to them before? Any advices?

I’d go back to oem and see if the problem still exists.
Eliminate any changes before last know working solution.

Even if you have to buy new O2 sensors, it’ll be cheaper than paying any mechanic diagnostic fees.

If you still have problems, then get some help
