Answer:
Anytime a check engine light is on, the first step is to get the codes read from the computer so as to have some direction for diagnosis. Many things can cause a check engine light, and many things can cause the problem you are having. You could be having a sensor problem, a wiring problem, a fuel pressure problem. Getting the codes is the first step.

Question:
What is causing a code of P0107 on my delta 88. 1996 olds delta 88. 3800 V6 Warning lights = check engine codes = P0107.

Answer:
Both of those trouble codes are for the MAP sensor (Manifold Absolute Pressure). If you take the plastic cover off of your engine, you can see the MAP sensor is located in the upper intake manifold, on the right side(passenger side). It is on top of the PCV valve access and will have a wiring connector running to it. Usually these codes set due to a bad sensor. It would be a good idea to remove it and look for any debris in the hole.

You can also remove the top of the PCV cover by turning it counter-clockwise to release it from the two tabs that hold it in place. If you have recently replaced the PCV valve or need to do so at this juncture, be sure to not forget the two o-rings that are inside it. Failure to replace these or if you leave one out, you will have a major vacuum leak and the car will burn oil. If this is the case, it can cause your MAP sensor codes as well. Your best bet is to replace the MAP sensor, and PCV valve kit.

Question:
Where in the heck is the EGR valve on this car. I have looked all over this car the only place i think is in the intake manifold. It is the 3800 V6.

Answer:
The EGR valve is located on the back side of the engine, between the throttle body and brake booster. Without any stored emissions codes or the readings from your test, it would be impossible to help with this problem. We need much more information on these problems. Removing and cleaning the catalytic converter as you said, is not going to do anything.

Question:
I have a Buick Oldsmobile 1993, when i back up it screeches like something is dragging and it also, seems stalled to back up. When i drive it does the same thing what does that mean? I also, have the break light thing on in my car but i don't know what that means.

Answer: It could be something in the brakes that is hanging up or broken and causing the noise. If it seems to be dragging the car down or slowing it up, then you definitely have a problem with the brakes. If the red brake light is illuminated on the dash, you are either low on brake fluid or have the emergency brake applied.
