HELP ! :SLC hesitates @ 1000-1500 RPM

Sounds like the throtle body needs to be cleaned. I found the passage ways at the top of throtle body right under where the three vacume lines attach was the main reason why my 93 sl2 was hesitating. Try cleaning that see if it helps.

Thanks, I'll give it a try...

Any others want to chime in..??

Make sure you use TB cleaner. Some carb cleaners aren't compatible.

A dirty throttle body is a definite possibility so it is worth the time to do a thorough cleaning using an old toothbrush, some good TB cleaner, and a soft rag. If that does not do it for you, then since it is a mid-90's, I'd change the spark plugs and ignition wires (assuming they were not replaced lately). Then go for the fuel and air filters as well. If it still hesitates, next I'd look at the fuel rail pressure (possible weak fuel pump) and then the injectors since they may be clogged. If none of those do it, then make sure the Coolant Temperature Sensor is functioning properly since it is a common failure (but this usually has a high idle symptom on start up with a warm engine and a rough idle as well).

Good luck
