Very very peculiar problem. I have a 1987 190e 2.3-16V and it is supposed to go 0-60 in 7.8 seconds. Odd tho how it takes 13 seconds!!!! I have a whole new exhaust system because I figured the catalytic converter was plugged which brought the time down to 11 seconds. I checked the camshafts and the lobes are fine. Any idea what this could be? Possible distributor cap or the camshaft timing? Would love to hear some input on this and if someone has had the same problem or not.

If you just throw parts at it that could be very expensive. Do you have any error codes? I suppose it could be a lot of things! How about Compression? Air filter? Wires, dist cap, AMM? Timing? What have you verified already?

From what I have seen on other sites, your 0-60 in 7.8 is a little optimistic. 13 sec. is slow.
I would suggest you start with the obvious (and cheapest) steps.
Is you accelerator cable properly adjusted for full throttle opening? Air filer and air intake clean? Then:
Spark plugs, distributor cap, rotor spark plug wires (?)
Fuel filter, clean air intake, check timing.
Now that the external engine ar in top shape, do a complete compression check and leak down test.
