Here's the issue I accelerate and at right around 5500 rpm the pcm does a reset with the swing of the gauges and the trip meter reset, also my wideband looses power and resets. It does the same thing everytime. totally stumped.cutout2.hpl
I attached a short datalog, frame 195 is where it does the reset, if you look at the afrs you can see how they drop down to 10 that's the wideband powering back up.
I'm thinking it's somewhere in the electrical, I datlogged the voltage and it does it everytime.
If someone knows what's causing this I will gladly paypal you $50. Worth every penny to get this resolve.
thank You
Also I recently installed 28" rear tires with 26" fronts so the abs, brake and tcs light are on.
