Ok, most of us here are amatuers but this just makes me fume. During the winter, I had a loss of confidence and sought a mechanic willing to work on my car. He admitted ignorance in all things DeLorean and I told him that if he were a normal, competent mechanic that he could handle working on a Volvo engine if I supplied the manuals. I ended up paying him $400.00 to teach -him- about the fuel system. I told him I suspected that the primary pressure regulator was rusted shut. He argued. I told him I was paying him to do what I want. So we pulled the fuel dizzy off. I was right, he was wrong. We freed the regulator up. Against my wishes when my back was turned, he opened the fuel dizzy. Now it's ruined. It leaks. He put wrong size O-rings on the plunger so it doesn't move freely. Ok, fine. I'm resigned to a new one. No problem. Next, he noticed the O2 adjustment screw was plugged up. I told him this was correct. The DeLorean has -electronic- idle control. "No it doesn't". And again, behind my back, he drilled out the plug and set a screw in it thinking he was setting the idle. He also drilled into the 3mm allen head adjustment screw. I can't adjust it now because the screw head is hamburger. If anyone has a spare screw of this type, or a spare venturi off of a parts engine for sale, please contact me offline. Thanks, Rich
