Just wanted to let everyone know that I had a fellow DML'er give me a ton of help with my car last weekend....I read the list a couple times a week. I know whenever David Teitelbaum gives advice it is honest, to the point and very informative...After exchanging a few emails he agreed that I could drive up and have him go over my car in person! Having watched him do the door adjustments at the spring social you know that David has an amazing array of tools and really knows the car well...On top of his technical knowledge he truly enjoys working on the Delorean. I was having a slight rough idle and just wanted the reasusurance of someone like David to go over the car. It was a bout a 4 hour drive and was the longestg I had taken in teh car..that alone makes you a little nervous...The car drove flawlessly. The first thing David did was check just about every operation of the car. Diagnosing any problem on this car and requires skill and knowing that each part is doing its job...We took out injectors, cleaned them. We reset them with new seals. We took out all 6 spark plugs, cleaned and regapped them. David checked just about every electrical connection in the engine. From time to time he would find a broken piece of plastic or missing clip. He would then go down and magically produce the exact piece you needed! Once he was comfortable that everything was correct he then began diagnosing the problem. After scoping the car and checking relays and other operations of the lambda system he was confident the problem is a faulty 02 sensor and then a slight adjustment of the air/fuel mixture. I also need to have a valve adjustment to bring the car up to top running condition. After about 5 hours of work David still wanted to check other things under the car to make sure everything was okay for my drive home....An oil leak here, a coolant hose that needed a slight tightening, checking the operation of all lights...He wrote down a few odd parts I should pick up. I could have stayed all night but had a 4 hour night drive and I had to get back on the road.... (David and his wife even offered to let me swim in their beautiful outdoor pool but it was 30 degrees, 5 inches of snow on the ground and I forgot to bring my swimsuit :-) As all of you know after doing alot of work on this car sometimes you can cause a problem or get stuck doing something without a spare part and leave the car undrivable. It can also make you a little nervous taking a long drive after working on the engine. I drove home with no problems and the car again drove perfect.... Also, I recently bought a BTTF pinball and David took the time to go over his machine with me and gave me trouble areas to watch out for and other advice.... In all I owe a great deal of thanks to David for all his help with my car. He offers advice on the DML for the love of the car and expects nothing in return and because of people like him owning the Delorean is possible and the DML is a better place... Mike C 2109
