First take a look if the ABS light is on, if yes, check your OVP relay.

Behind a plastic cover in back of the battery, it is a black box about the size of a pack of cigarettes. One is the fuel pump relay the other is the kilma or climate control relay. You will see the fused OVP relay also.

if its a 116 engine, that is, it has one air intake on the passanger side to the air filter then the relay is on the firewall, on the left looking at the engine is the ecu, big black thick connector on it, next to it directly on the right is the fuel pump relay, maybe marked kickdown, next to that klima, for ac, next to that ovp overvoltage protection. if u have 2 air intakes for 117 engine let me know, I can look in my books for you.

89 190E 2.6 you bought the car six months ago and it ran ok you had to tun it over for 5-10min but you would start the car needed a cat so you took it in to get one but the car sat there for 2 months?
It probably just needed an OVP (over voltage protection) relay that directly behind the battery and only cost about 89.00. It's also possible only the 10amp fuse is blow in the OVP. This is especially likely if your ABS light is also on. Exactly the problem I have with my 89 190E 2.6.
Hello My MB 560 sel 87' sometimes turn on the a ABS light and simultaneously the engine accelerates at 2000 rpm I need help in the diagnosis?
This is your OVP (Over Volt Protection) relay. It will probably fail completely eventually. I think they're about £135 (part no 201 540 32 45) to replace. It's the small metal relay box between the engine and cabin bulkheads, close to the wiper pivots - easy to replace yourself.
1990 Mercedes 300e where is the ac relay located?
I find that the tacks are not usually bad. The Problem is the fly wheel sensor atached to the transmission houseing.This picks up rotation RPM's of the fly wheel ,sending the information to a control unit that controls the tack. The pick up unit can get dirty with oil and dirt or metal particles from stater gear, or the fly wheel [ring gear] can becomedirty enough that the pick up magnet does not make a signal. Also check the wireing for this unit to make sure ,no breaks or bare spots that can contack metal. Before doing all those things check your fuzes. Those old type fuzes may be alright but get cruddy over time and need moving around some to make contack. Sure hope Iwas able to help. The A/C relay, A.K.A. the KLIMA relay, is located behind the battery next to the firewall. It is a little black box that plugs in next to the OVP relay.
