Help me out here guys. I have have 4 02's, but this is my 1st tii, she seems to run rich, i have petronix, and a blue coil, other than that it is stock. I ahve played with the timing some and seems to have no effect on the mixtures.

First of all, the blue coil is wrong for a tii. You need the Bosch red coil, as supplied originally. That's not your rich problem, but in the process of elimination, you have to start somewhere :)

a) does the car startup fast and then slow down to normal idle? This air/fuel mixture will be rich if not set right or is stuck in the "cold" position. This could be a faulty/bad warm up regulator. If that's ok, then

B) is the cold start valve shutting off? It could be leaking gas and running rich.

At the end of the day, the correct setting of the tii O2 mixture requires special tools and the right equipment. Try a qualified TII mechanic in your area... if you say where you live folks will heip.

Hope that helps,

Keith
