2007 Mazda 3 S 2.3L Long Crank Time VIN: JM1BK32357
The problem has gone away. Customer is driving it and will let me know if it becomes a problem. My belief is its going to need a fuel pump as the suggestion on it being a stuck open purge solenoid doesn't make sense as it never sets and evap codes (still sligh...

We found the miss/surge only occurs with the coolant temp at 80°C; the engine would smooth out at coolant temps lower or higher than that (verified by installing variable resister in place of ECT sensor.) We suspect there's a glitch in the ECU that causes the ...

Hello all. Thanks to all who replied. They were all valid suggestions. A leaking valve made more sense to me than a plugged exhaust, so I went ahead and performed a leak down on the #3 cylinder. This did verify that the intake valve was bad, causing the issue ... Trouble codes: P1131, P1152 (Lack of H20 - B2 S1 switch indicates rich).

Ty hit the nail on the head. The positioning sensor was 180 out. I knew it was possible to be 180 out, but I didn't think it would run at all if it was. The vehicle also had a bad idle speed controller and after replacing it, I had to set the timing. Also foun...
