Question
QUESTION: I have the above, showroom, just put a 383 stroker in it pulled out all original componants,but check eng. lite on dash is now on, any thoughts on how to put it out, thanks ,FRANK

ANSWER: Hi Frank:
I assumed you reconnected all the sensors to the new engine. If not, the light maybe on for that reason. If everything is connected correctly, then the new engine is not meeting the computer specs that controls the check-engine light. Most importantly, air/fuel mixture and exhaust emission.

QUESTION: Hi Vern, no there is nothing at all put on this motor, zip,pure HP, i took everything out except computer,if i take that out will that solve it? thanks

Answer
Yes. That and removing the bulb or fuse will turn the light off. Keep in mind, many states inspection still inspect automobiles older than 1996 with an exhaust sensor in the tail pipe to determine CO2 emissions. Also if a check engine light is on, it won't pass inspection. So check your state laws before removing the computer or see if your new engine can be connected properly to the computer.

Expertise

Visit my website at: http://www.classytransportation.com/ I can answer most questions about autos built in the 60's 70's and 80's. Specifically, Lincolns, Rolls Royces and the Excaliburs. Mechanical issues and technical questions are my expertise. I also have a general knowledge of most older automobiles. Keep in mind, I can only provide answers if the questions are very specific and complete. Without details, I can only speculate and that's not good for solving your problem.

Experience

I have owned and maintained Silver Shadows for over 10 years now. I find most mechanics and even Rolls Royce mechanics have very little knowledge about these automobiles. I have researched these cars in quite a bit of detail and can pretty much tell you what is wrong, if you can describe the behavior in detail. I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis. I am the owner of Classy Transportation, LLC a luxury limousine service specializing in antique cars, classic cars, vintage cars and exotic cars.
