My 88 300SE has been having stumbling at idle and initial acceleration problems. I've gone through the serch function and it appears this could very possibly be an OVP problem. I checked the fuse and it's fine. My question is, before I go out and buy a new one to see if this is the problem: Is there a way to open the OVP and clean out the contacts? I've located the OVP and removing it should be simple enough but I'n not sure how to or if I can open it once I get it out. Any ideas? I don't want to start prying at it and destroy it.
