Why can't I pull trouble codes for my 1994 Buick

You need a specific adapter to scan your trouble codes. Vehicles prior to 1996 use OBD1 scanners, which are very expensive. Your best bet is to call around a few shops in your area and ask what they would charge to diagnose the code. It sounds like you may have more than 1 problem. The emissions could be due to a bad oxygen sensor and acceleration problem may be due to bad plugs, plug wires, clogged fuel filter, rotor and distributor cap, etc. Do a tune up on it, then see where you stand. At least you won't have to pay a shop to do it if that fixes your acceleration problem.

How do you manually get trouble codes on a 1991 buick regal

Locate the ALDL(diagnostic lead/connector) which is usually on the right of the steering column, and as you are looking at it, take a paper clip and and place it to jump the 2 right upper terminals. Count the flashes, ---- -- = 42(as an example). Let me know if you need further help.

1997 buick lesabre, engine light stays on

The are many things that can cause your "check engine" light to stay on. One possibility is that although you have fixed the trouble code for your crankshaft position sensor, the code has not been erased from the computer's memory. Another possibility is that you have another issue going on that is causing a new trouble code to come up. You're going to need to have your car hooked up to a ODB-2 engine code reader to see what the issue is. These code readers are available for purchase at any auto parts store. In addition, many of your local auto parts stores will check trouble codes as a free service to customer. If not, many parts retailers offer the option to rent one of these code readers. Which ever way you decide to go, run a full engine/emissions trouble code check. If the only code that comes up is the code that came up previous to fixing your positioning sensor, then all you need to do is erase the trouble code from the computer's memory. (Most code readers have the option to erase trouble codes, but if you're going to rent or buy one, I would suggest that you check to make sure that the code reader that you're getting is capable of erasing trouble codes as some code readers only indicate the codes and will not remove them from your computer's memory.) If your trouble code scan reveals other codes, then you'll have to fix and erase them as they arise.

FYI- In my experience, I've noticed that 95% of the time that a check engine light/trouble code arises that it is usually an emissions problem (oxygen sensors, mass air-flow units, MAP sensors, etc.). However, General Motors products are notorious for getting trouble codes for having loose battery/ground connections and for having worn-out fuel caps. With any GM vehicle, I always check these two things first to try to save me from having to look further than I need to.

Hope this helps! I'm sure once you've scanned your cars computer and erased any existing trouble codes, that you'll stop being annoyed by your check engine light, as I know how bothersome it can be. Have a great day!
