Yeah, I think all the recent problems are likely computer related.
These ECUs just aren't up to their tasks.

The problem, according to NHTSA, may be linked to onboard computers.

the problem could be linked to the onboard computer, or electronic
control module. "

Really. The ECUs definitely have problems, but please show us a better
way that doesn't involve electronics. Carbs worked well, but wasted
fuel. Without electronics, are air would be dirtier, we would use more fuel.

Please suggest a better way.

I didn't read his comments to say ALL ECUs, just the ones in these
vehicles. Most vehicles with ECUs don't have this kind of stalling
problem.

I have seen tons of problems with a range of ECU's, particularly GM.
GM had a run of ECU's that were very dangerous in that they would
stall (die) under full speed freeway conditions if you lifted your foot from
the pedal.

I fought the f***ing dealership for a long time on this, and they didnt
even read the bulletins.

Finally, I got to the right guy at GM and he roasted the dealer over the
coals, but got me a new ECU under warranty which cured the problem.

We went electronic because it was powerful and simple. There were
certainly mechanical systems, even with FI. Fluids computers might have
been able to take some of the trouble out of the system.

Military standards for components would have helped insure that the damn
ECUs would work longer than a string of Christmas lights. But this might
have
been very expensive. Adequate quality would not have been expensive and
could
have removed most of the problems.
