I have had starting problems with my 91 300e. i replaced spark plugs(were bosh platinums) with correct spark plugs and adjusted eha, for the most part solved my problem. i looked at my ovp and it only has one fuse and there is no place for a second fuse? i thought there were supposed to be 2 fuses in it. is this a problem?

P.S. could a bad fuel pump/ filter cause slugish acceleration?

thanks in advance
