car running like crap after header install-need help
me and a buddy of mine installed some pacesetters on my car saturday, they are the off road version. the only problem is my ORY didnt come in in time so i had to drive it home open headers. it was loud and annoying, but my car ran like crap also. it felt like it was missing or something. so i took it today to get the codes read, i thought maybe one of the spark plugs i bought were bad or something, and these codes popped up:
P0140
P0160
P1134
the first two are because i have no 02 sensors, im still unsure of the last one. i looked it up and it says: "H02S transition time ration sensor 1"
my question is, does anyone know what that means? is the car running like crap because its open headers or have i uncovered another problem?
any help would be appreciated,
thanks,
anthony

open headers never gave the problem of which your describing to me so you must have stummbled upon something else. Unless its one of those things that "some cars are okay but others act wierd" sort of things but I dont believe so. Good luck with the problem.

More than likley the car is running like crap purley because your running open headers. First off get O2 simms for the rear or have them deleted, secondly your front O2s are sucking fresh air on decel making the car think it's super lean. To run open headers the right way you need about 18"s of pipe behind the O2 sensor.

Here's the exact description of the purpose of the P1134 "TIME RATIO BANK 1, SENSOR Monitors the ratio between rich to lean and lean to rich transition times, The ratio of rich to lean and lean to rich oxygen sensor transitions."

whats funny is 5 codes came up, and 4 of them were the first 2(2 times each).
JRP figured the PCM was going squirly because of the open headers rich to lean mess.
thanks for the input. for those that are curious i will post up result after i get the ORY in.

what you may be experiencing is that you are feeling/hearing the individual cylinder exhaust pulses up under the floor of the car and it seems like a miss
now it may in fact be running like crap with no O2 sensors in it but put it to the floor and hold it while you run through a few gears and it should run steady then, but its gonna be so loud and annoying that you wont be able to feel a whole lotta grattification from the headers

of course, the more input i get without hearing that its a major problem, the better, so keep em coming!

again sorry on the ory delay, i threw codes when i first did my headders, i forgot what the code numbers where but the codes where insufficent switching (or heating i dont remember) due to no rear o2s, but your car is probably runing bad due to lack of exhuast back pressure, i ran mine with open headders just to hear it and it ran like ***, once you get the ory get the pcm tuned, itll ran great

thats cool man, im not mad at you. i was just thinking of this being like running open headers on my old school small block i had in my 72. was looking forward to turning heads and annoying everyone with the noise for a few days. didnt anticipate my car running like crap and scaring the crap out of me!

update, i got the ORY on this morning, and all is well. i reset the PCM and the car runs great. man i can feel the difference. and for anyone who is curious, the TSP rumbler sounds great with headers!
and a little advice, dont ever try to run an LS1 open headers!
