Anyway, I’m stuck in the same boat. I got a 94+ header with the sensor on the bottom and it has poor bottom end, especially when cold. You can actually feel it kick when it warms up. I’m wondering if I can maybe wire a heated sensor to a thermoswitch, at least for the winter
[QUOTE=~ink~93jdmDA9;2093920]do what 2ndJenn said by reseting the ECU after you install the damn sensor. Just install the DAMN header its a DC Sports header for gosh sakes DC Sports is a badass company and very reputible so install the damn header get better performance like im sure you wanted which is why you bought it an who gives a F*** where the damn sensor is…DC Sports put it there for a reason and gave you the extension for a reason…it will still work perfectly fine, so install the damn headers already an stop bitching if you want to bitch then return the damn header already…hope you dont do that though cause DC Sports headers are freakin amazing!!! sry if i came off like a dick but this post is getting annoying an dumb lol :bang:

I’m sorry but are you retarded or something? If you bothered reading this thread at all you would of realized I already installed the header 3 weeks before this stupid ass post. :bang:
My mistake, it is actually a Megan header. But yes it is for sale if your interested. Hit me up. Integpk@hotmail.com
Did you get a 4-1 or a 4-2-1? A 4-1 might explain the poor bottom end. As for mine it’s a 4-2-1 and I don’t notice any real loss in bottom end once warmed up. And when cold I’m not sure becuase I always take it real easy on my car until it is up to temp. If the 92-93’s don’t have a heated o2 sensor and don’t have that problem I don’t see why we would.
It’s a 4-2-1. I’m gonna try replacing the senor. After all, it’s a cheapo Bosch 
after installing the header you lost bottom end torque. thats almost impossible even if you had a 4-1 you wont really loose torque considering how bad the oem manifold is. even a defective o2 sensor wont make you loose any torque, your fuel consumption will only go up a little.
Well, I replaced it with a used OEM sensor and it didn’t bog on the bottom, but still wasn’t right, and still threw a code when it was really cold. I got to thinking, and since the B1 has a higher pressure FPR than the A1, maybe the cold, dense air was leaning it out too much (which was supported by how white the inside of my exhaust manifold was, and the 36mph I was getting in the summer) so I pulled the vacuum hose off and plugged the manifold port and now it’s running much better. Is it safe to run without the vacuum for the winter? Or should I find a 94+/adjustable FPR?
do you still have your stock FPR? you can just put that one back on.
