I have just removed the pre cat and the
cat from my 88 190E since it was partially
clogged. The car now is even worst. The
car is hesitate to go, look like to mixture
is too rich and the idleling is rough as well.

What could be wrong ? Do I need to retune
the CO and HC again ? The car run fine if
I disconnect the O2 sensor wire under the
seat but I feel is is less power at high speed. (Probrary it is running lean).

your help will be appreciated.
