1994 c280 problems
 

my 1994 280 has multiple problems and I'm wondering if all points to 1 fix. It looses power when accelerating (not always) as if it is not running on all cyclinders, but if I restart it, it runs normal. It has a irratating noise coming from the trunk, right side, the engine temperature rises to 100-110 in traffic when the outside temperature is above 90 degress, the ac fans go off and on. Are these mulitple fixs or does it point to 1 item. Thanks

sounds like you have multipal problems.
time to take it in and have it diagnosed properly.

you are also in that area of the bad eng wireing harness
so have that checked closely.

I've had the original harness replaced about 3 years ago. Could it go bad again this soon?

most likely not. but i would recommend that all the connectors
be rechecked. there have been issues of corrosion but mostly
were the connectors were not tight in their housings thus causing
bad connections.

Thanks,
I just ordered new spark plugs (f8dc4) and wire set (beru) w/ connectors. Hopefully that will correct the misfire issue.

I changed the spark plugs, wires, and connectors and everything is back to normal. No more power lost. Thanks

Good Ole Tune-up fixed the problem ehhh

spark plugs fixed the temp problems?
