200tq check engine light, but no codes!?

[Ivan Tuma]

Ti,

Turns out that the ECU was right .... the "mechanic" who performed the 
last timing belt installation apparently didn't properly allign the 
distributor rotor
with the notch in the distributor housing (it was about 5 degrees off of 
center). That's why the Hall Sender fault code was being reported.

I adjusted it today, and no more check engine light ... runs better than 
ever (so far). Now I can continue working on my resistor mod. I got 
14psi of boost
today (TOOO MUCH, I hit an overboost fault) I need a bigger resistor 
(around 1.4kOhm) to bring it down to a conservative 12psi. Currently I'm 
at 9 with just a wastegate spring.

Anyway ... thanks for your advice.

Tschus,

Ivan
