I've been driving my 82 y./o Pops 300e ('86, 190k miles) for a few weeks.
The car started and performed great the first couple of weeks.
The car has since developed problem which is becoming a safety issue. On a recent 2 hour interstate trip, the car began losing power. The issue was instantaneous. The car would take no more gas/acceleration. Also, the MPG/fuel efficiency gauge moved to high side (appox 4:30-5 oclock). After a few minutes, the 'normal' mode would kick back in - car would ride normal and fuel eff would be normal.
The issue happens now everytime I drive the car. It is particulary unsafe when I pull away from a stop and the car will not accelerate and threatens to stall. Last night, in driving rain, this happened as I attempted to cross a large intersection.
Thoughts appreciated.
