I need some help
 

I have a 93 SC300 and i just installed some headers and midpipe and i have a o2 simulater to install and was wondering if anyone knows how to install it.

The car tries to start and wont and im guesing its cause there is no signal from the o2 sensors.

The old o2 sensors are different from whats on the headers so thats y i didnt use them.

hey i have the same problem..where did you get the o2 simulaters

i got mine with the headers from the guy

A couple questions for you:
What header / frontpipe combo do you have?
What did your stock O2 sensors look like? Threaded or flange type?
If your header came with a simulator, I can assure you it isn't meant for the primary sensors. If anyone needs help installing a O2 simulator for the secondary o2 sensors, I can definitely help you there
