1991 Toyota Celica GT Engine 5S-FE Auto Trans. Mileage: Car 158,000 Engine: unknown junk yard replacement. Problem: Will mot pass Maryland emissions test. Hydrocarbons: State standard- 1.00GPM Inspection result- 1.97GPM Fail Carbon Monoxide: State standard- 20.00 GPM Inspection result- 71.41 GPM Fail Oxides of Nitrogen: State standard- 2.2 GPM Inspection result- .636GPM Pass Current gas mileage mostly highway driving is 22.2 MPG The engine starts and runs well and occasionally is a little jerky when not under an acceleration load. I replaced the engine in March 2007 with all new tune up parts at that time and have put 7,000 miles on it since then. After failing the emissions test I took it to a shop listed in the brochure given to me by the state testing office. The shop found a vacuum hose that had a hole and replaced it. They also checked the timing and scoped the engine. Next they checked compression and cylinder leakage with good results. They checked the emissions at 900 RPM and the results are; HC 214 limit 220, CO 1.18 limit 1.20, CO2 17.0. They told me to use 40wt oil and run it through the state dynamometer which I did. The results are listed at the beginning of this statement way above. I then decided to look into this myself a bit so I pulled the spark plugs and found all four of them with thick black carbon, much the same as the end of the tail pipe powdery carbon. The next thought was that maybe the cold weather injector was stuck or being told to spray while the engine was hot so I removed the injector, plugged the manifold hole and started the hot engine to see if any spray was there, none was observed. Since I had the old engine I replaced the injector anyhow but no change in fuel mileage was observed. That brings me here any ideas?

We have a 2001 Windstar LX that has recently begun not unlocking the passengers side rear door when pressing on the main unlock button. If we try it a few times, it was eventually unlocking. Well today it did not want to unlock for anything, and we repeatedly tried it and started to smell something. It smelled like that "burnt electrical smell". The other doors still lock, but obviously something is not right. And if something burnt up, seems to me it must be local to that particular door as the other door locks still work. I would like to know how all the doors are controlled, how all other doors can work and not this one. My kids ride around in that thing so having smelled something burning isn't a good feeling. But I want some understanding of what is in place before I go into the Ford garage and get a line of BS with a huge estimate to fix the problem. I just want to be armed with some info on how it works and if there is any easy way to fix it. Thanks in advance.
