[urq] Engine stall under heavy electrical load

[Mike Del Tergo]

The first place I'd look is electrical, not to the mixture etc.  Sounds like the ECU or injectors or both are not getting enough juice under high electrical load.  Could also be bad grounds in these circuits that would have nothing to do with the starters ability to do it's job on a different circuit.  A qiuck load and or continuity tests on the affected circuits should ferret out the problem.  After all that has happened to get the car EFI'd, it seems silly to threaten tossing it out of the garage for a probably simple electrical gremlin.  > From: Louis-Alain Richard <laraa at sympatico.ca>
