Check engine & SRS light!!!!!!

[exzercist]

i just put a autometer boost and a/f gauges in my car, hks bov, and a 3in ss downpipe which eliminates the cat. i just put all this in yesturday and this mornig i threw a check engine light and srs airbag light. i figured it was becasue of the downpipe. any suggestions on what it could be and how can i get them to go off??????

go and get the code pulled....I got a Check Engine light after I installed a Greddy EBC. I had a P1400 Manifold Differential Pressure Sensor Circuit Malfunction. Just called the dealer to see how much the sensor was....cost $130

Get the code pulled like he said, but are you recirculating the bov? or venting? That won't help.

For the SRS light you will have to get it reset at the dealer unless you wanna buy the special SRS scan tool.

well what caused those to come on? thats my real question because i didnt realy do muvh to my car and now these lights come on. i never had a prob before but now its all messed up.

I dont know what would cause the SRS light to come on since you didnt unplug any airbags, unless when you installed the gauges maybe you tapped the wrong wire (just a guess), what wire did you tap for 12V? And the CEL might be from the downstream O2 being gone (what did you do with it after you took off the cat?).

I tapped into the cigarette lighter for power and the downstream o2 sensor is still there. the O2 sensor is after the cat so if you take the cat out with the dp replaces it the O2 sensor is still on the other half of the pipe.
