Are my coils failing?
Ok, so I finished up my MSM Swap into my 99, The tune is looking a LOT better and was running a lot better. I have a DIYPNP MS2. Here lately, the engine wants to die. And by that, I mean the Tach drops to zero and I lose power. The lights, radio and everything else stay fine, but the engine feels like it wants to shut off. At first it was just random, during my 125 mile commute. Then it was whenever I went into boost... Now it is pretty much any thing about 3k RPMS.
If I let the car cool down completely, it will run ok for 30 or so minutes.
When it dies, I can usually push in the clutch, it will backfire, then start back up. Sometimes I have to downshift and left off the clutch before it will.
I have also noticed a sound under the dash when this happens, That could be described as either a relay kicking on and off really fast... or maybe arcing.
I have checked my grounds and all wires. Everything SEEMS to be good. I pulled the ECU apart last night and could see no signs of Carbon arc traces.. everything on it tested ok as well.
My MSM motor is completely stock, except for an airbox and MAF delete. It has 44k miles on it.
