Hey guys,

Im set to move across the country in 2 days and I have been finishing up work on my 01. I took it for a shake down drive last night and everything was going well until (fortunately) right when I got back near my house. It starts to surge and stutter and wants to and does shut down. I took it for a short drive the other day and I had the same issue. I chalked it up the Hot Rod VP that WAS in it, because it was giving me a really hard time loping at idle and low load. I went ahead and switched out the VP for a DAP SO unit, since I had wanted to switch back to an SO anyway. I finished that up along with a new cam sensor, and she started and run beautifully. So as I got home it was surging stuttering and shut down. I could get it to turn over and catch for a second but not run. Fast forward to this morning, I pulled the VP connector off and put it back on and it started right up.  

The codes, which have not returned since I cleared them were a p1689 p0232 and p1693.

 

I ran the diagnostic for the p0232 and I am getting odd readings. The voltage fluctuates between .09 and .5 volts My power probe says that somewhere I am getting a 13-14v spike but its so fast I cant see it on the meter. I probed the wire at the VP connector and back probed it at the ECM as well. Same readings. The diagnostic says you need between 9 and 14.5 volts. The diagnostic seems pretty conclusive that if you dont have that voltage, the ecm is bad. I just got a new ECM from Auto Computer Specialists.

I thought maybe since I had pulled the VP connector and reattached it that maybe I just had a crusty connector or bad wire, but the readings are the same at the ECM as mentioned.

At this point in time all codes are cleared and not returned. I just cant risk going out on the road without knowing whats up.
