It's 7:30am and I have been working on it all night.

Swapped on another opti, still does it, but does run a little better
Swapped pcm's, still does it
Swapped to a 1 bar map sensor and put in my 1 bar tune, still does it
Weird thing is on the 1 bar tune I had to add 22% fuel to get back to where I was before when I made the tune :???:
Started checking ohm's on all the wires from plug to pcm...
icm/coil/tps/injectors/iac all good


Opti harness I can't get off without removing the waterpump(damn the idea of a wire tuck)...so started chasing my wires back from the opti harness to the firewall and noticed the black tape around them is burned off. It's way underneath where I couldn't see it until I got my head way up in next to the cross over pipe from underneath.

The wires are about 2" from the crossover pipe, I tied them up very well and took my time, I'm really suprised they burned where they are at. I guess later today I will try to tear the harness out and go through it all, not looking forward to that.

Sleep time now. :yup:

 

justin, at least you made some practice. If you want, i'll be in indep. saturday night, i could always come give ya another set of eyes

 

Here is a pic of the graph from the dyno a few weeks ago, finally got a hold of it.



That doesn't look like it's valve train related.
