Hi all, I've used this group to find tons of answers before, here is a
first post after searching for some time.
1986 420 SEL
About 4 of the last 10 times I have started the car, the following has
After about 1 or 2 miles of driving the car begins to bog down.
Pressing the accelerator down will cause the engine to struggle/bog
down, then finally catch up to the throttle level I am giving it. The
efficiency gauge goes all the way into the red until teh engine/car
catches up to it. Giving it VERY gradual throttle is the only way to go
from a stop smoothly, though it takes forever to get up to speed.
The real strange thing is why it happens only a few times while
driving. Other times, it runs strong.
- Injector nozzles replaced @ 60K ago
- fuel filter changed
- premium fuel (2 or 3 tanks used now)
- Not driven below 1/3 tank of fuel
Thanks in advance on any thoughts you may have...
