Hi! I had mpguino in my car long time ago then I removed it and now I tried to put it back in and run on some problems.
My mpguino now causes misfire when i connect it to car. Wiring is the same as before and it run without problems. Vss works normal, but as soon as I connect inj, idle gets rough, I can smell gas and got CEL and codes - random cylinder misfire on 1. and 3. cylinder... I am pretty sure wiring is correct, only differences are - I built a stand alone circuit refering to this diagram - http://opengauge.googlecode.com/svn/...no/mpguino.png and intead on using 50k resistors I used 67k and 1/4w zener diodes which are smaller then those I used before. What could cause these problems?
I googled around and could not find simmilar problem.
Vehicle is Lexus, so basicly a Toyota...
Thanks!
