Well i did that and i see any numbers at all :/ that wire is yellow right?

the problem is NOT your supercharger as your WOT the SC is building air pressure (i bet the gauge reads higher than it ever did before!) till it cant anymore, the problem is more than likely a lack of exhaust flow (would make a wierd sound) possibly broken/plugged cataltic converter/ or a severly colapsed inner tube on the double wall downpipe. which will not let the engine rev/breath.

real simple thing fer ya to test, jack up the front of the car and put on stands then on the exhaust downpipe take off the two 15 mm bolts holding the downpipe to the rear manifold then start it up i bet it will run lots better, take it for a drive

this is why backpressure is a bad thing in exhausts
i have seen the same problem in two SC 3800'* (one buick regal GS and the other a GTP-he crushed his cat going to fast over a bump or somethin-squashed flat!)

The terminals are visually numbered or anything, you gotta count over to the one you need. I don't remember what they are because I'm not lucky enough to be able to do that trick lol.

Ok let me fix this i founf a yellow wire that said A dn B on ti and i pulled it apart (is it a wire or a box?) and i put the paper clip in and no numbers came up on the dash.

Number aren't gonna show up on the dash. The Service Engine Soon Light will flash. Under the dash almost in between the gas pedal and brake, closer to your knee, you'll see a plug in for a scan tool.....That'* where you put the paper clip into it'* respective terminals to put the cars computer into "Diagnostic Mode" When you do that, the Service Engine Soon light should flash once......twice. Meaning Code 12 which means that the cars computer is sucessfully in "Diagnostic Mode."

Here'* an example. This is what will happen when you plug that paper clip into the connector and turn the key ON....NOT RUN:

Flash......Flash Flash= Code 12 *This will happen 3 times before Flashing the codes out, and after flashing the codes (when it'* done)*

flash flash......Flash Flash Flash Flash Flash= Code 25 (Has no meaning I don't think, I just made it up.)

Flash........Flash Flash Flash Flash= Code 14 (Another Made up code)

Assuming you only have 2 saved codes in the engine computer above, it will flash Code "12" 3 times again to inform you that the code flashing process is complete. If you think you may have miss counted any of the flashes, leave the key on, and the process will start all over again. By flashing "12" 3 times, then the codes, and then "12" 3 times again when done.

Hope this helps.

Damn this is tech info worthy.....lol

Ok, Well i thank you sooo much for clearing that up for me all it did was tell me code 12 the whole time so does that mean someting good?

No problem......It means that you have no codes stored in your PCM.

Brandon, put your location in your profile. And do a full tuneup. Plugs, wires, air filter, fuel filter, PCV valve, etc.

ok , well the car just got a tune up about 1 month ago., i did hit some big speed bumbs today and it sound like part of the car hit the ground, sound like a problem?

I got 20:1 that you smashed your catalytic converter then or pinched your exhaust pipe damn near shut....That'* gonna be expensive......Take a look at the exhaust pipe and inspect for crimps, kinks, and bends that aren't supposed to be there. (Where ever the most scrpe marks are)
