Brake Warning indicator

[Larry C Leung]

Josh,

Your the MAN!  Added an 8 ga ground, cleaned the others (had measurable
resistance, more than 10 ohms) and the results are:

1.        Sensor coding has stopped
2.        Brake warning light has stopped
3.        Better (not great) drivability. Car starts right up instead of
starting and stalling.
4.        Smoother idle.
5.        After two hard (such as they are) hard runs, where
INTERMITTENTLY it runs
                like a rocket (stock chip) I replaced with the chipped
ECU. Whoa! Forgot
                what a chipped 10V will do. I wonder if the percieved
poor drivability is
                "normal" for a stock 10V  (NOPE, car should never go
flat, and have to
                "back off " then go again to get boost). Anyway, I'm
going to try the new
                ECU to see if fuel starvation is still an issue (recall,
new fuel filter, injectors
                new as of last year.)

Anyway, MUCH better. It's a drivable car again.

Thanks, Josh! And note, your diagnosis has even fixed Doyt's car too!
