Changed battery- Now car won't run- on 1997 Mercedes-Benz C230

Acts as if not getting fuel- sputters- Starts but can't accelerate. Ran perfectly before we changed battery

Newer cars need to relearn idle strategy after replacing a battery but your car shouldn't have this issue. Are the battery connections clean tight and secure. Check your fuses, perhaps a fuse blew, do a god visual check in the engine compartment to see no vacuum hose has perished or has inadvertently got knocked off, look for bad electrical connections.
