turbo cel

[blaze14501]

I have an o5 tc with trd suspension,sway bars,strut brace,exhaust,short throw shifter,18 inch trd wheels,and a stage 1 turbo kit.I'm getting 250hp at the wheels and 255lb/ft of torque.It runs great but i can't get my cel to stay off.I tried an antifouler and it lasted for about 20 miles.I would appreciate any fix help or advice.

its your short throw shifter. Seriously , you should have the codes read and find out what the problem is. CEL has much more to o than your O2 sensor.

yea, what kind of turbo kit is it, ZPI, you should really have a specialist check it out, what kind of engine management do u have?

its an o2 sensor code po128 if I remember corectly.I work for a scion dealer in pittsburgh and had it scanned a couple of times by our top techs and said that it was a sensor code.The turbo was perfessionally installed at a shop called hybrid dynamics,they do top notch work.As i said,everything runs great,but because its running leaner than the factory intended,the o2 sensor reads too rich and sends a cel code.I ordered a o2 similator and hopefully it fixes it.The computer is an e-manage with 550cc injectors.Wish we didn't have so many cats.Thanks for the replies.

maybe just a clogged or band oem narrowband. Try putting a new one in there. The heater element could be bad. 20Kohms 10 watt resistor jumpered to the heater wires would simulate a working one.
