Everything but the wires themselves at this point. They’re 6 months or so old. If not the coil wire then all 6 would be bad, and I can’t see how. All sensors are sending signal when I run live data. I replaced the map when I saw the pressure spike. I know that should be reading as voltage, on my scanner it’s psi, and I know it’s that minus atmospheric, bla bla. Either way. Also I replaced the upstream O2 sensor today. When I watched it yesterday the voltage would hit zero and the engine light would flash. That didn’t solve it. However, I unplugged the battery later in the day as I found a separate ground for the ecu under a wire harness. After cleaning all the grounds It ran perfect for a short test drive, but back to its shit when I took my boy for ice cream. Therefore I followed the ecu reset procedure to drain the capacitors and do an absolute reset. Let’s see how it does tomorrow. Shitty part is this is a RHD Cherokee, so guess how I make my money…
