  1. Ok, my software isn't Durametric, but it still does pretty extensive data logging. I'll let it run for a couple of days and see what it has to say. I'll report back when I have some good varied data. I'll even try to make it miss out on the road by being a leadfooted nutjob.
  2. Thanks, I'll report back on all of that. I'll be doing this in my driveway in neutral since I don't want to take it to WOT on the road while looking at DME numbers. Is it safe to let it sit there and bang off the limiter while going WOT and letting the info register on my tablet?
  3. Ok, I'll check it and report back, thanks! Also, just to be sure... the misses have never occurred at high revs, just at open throttle. I've had the engine revved pretty high at partial throttle with no issue. The misses have always happened when I stomp the pedal all the way down, before even having a chance to rev high. Are we still talking about the same thing, fuel-flow-wise?
  4. My Bosch Mobile Scan software on my tablet shows the real-time fuel info as the engine is running. Is there something I should be looking for? Should I be noting differences before and after a misfire occurs when I floor the throttle?
  5. Hey, thanks for the fast reply! I don't know if the coil packs have ever been changed, but I'll look through the giant pile of receipts I have from the PO. When we did the job it didn't look as though they were. I also went back the next day to make sure everything was connected properly and remained torqued down. I'm planning on going into the garage today, I'll check and see if any of the coil packs- especially on the passenger side bank- are cracked. I don't have a compression tester in my shop... maybe I need to find one. I changed the fuel filter in April, probably about 6K mil
  6. Hi everyone, I've been reading the RT Forums for a while but now I'm finally registered in order to try and track down an issue I've been having. I've searched for related issues through the forums already, but nothing is showing up which is a match for mine. '99 2.5, 5 Speed, 99K Miles Only upgrades are headers and catback. I've owned the car since March of this year and it's been great so far. I've even taken it to the local PCA Autocross. A couple of weeks ago I was cruising on the freeway when my CEL came on steady, no blink. There was no noise or indication to me that an
