i have a ford thunrderbird 1997.v6..i had the catalytic convertor replaced with a straight pipe because it would have been too costly to repair...now every like 30 miles when im driving the check engine light comes on and starts flashing and then it seems like the car loses power and acts like its going to stall...why is this?

LoL - dude did you also remove the 0xygen sensors ??
The car uses the catalitic convertor to control fuel consumption - and burn off extra fuel that the cumbustino chamber does not use ... if you remove it from the loop you will have problems.
IF you did remove the Oxygen sensors , you might want to go back to the shop that put the straight pipe on and tell them , to get a clue when doing shitty work and replace them.

Cars rely on many things to run properly. One of the things dealing with operation is backpressure. There should be a certain amount of resistance in your exhaust. The other problem that you are facing is from your o2 sensors. I believe that your car has atleast 2 sensors one should be before your convertor the other should be after it. Without your convertor your car is going to have fuel mixture issues because of what the computer in your car is seeing from it's exhaust. Also, not only is removing a catylitic convertor on a street use vehicle illegal (federal emissions laws), but most repair facilities wont work on it if is not there. As for your light flashing it is most likely due to a misfire condition that may or may not be related to your missing convertor. The check engine light in your vehicle is designed to flash if the cars computer detects what is considered a catalyst damaging condition. Most likely you have one or more cylinders that have an intermittent dead miss. If you know your way around under the hood I would suggest inspection of your secondary ignition components (plugs, wires, cap & rotor, or coils) and make sure they are okay. If not then take your car to a repair shop that has the ability to scan your cars computer and they can tell you what will need to be done to fix the problem. Also keep in mind that they may not be able to properly diagnose the problem unless they can duplicate the symptoms you are describing.

Your check engine light is coming on because of the removal of the catalytic convertor. You can buy a part called a mil eliminator to solve this. The car is feels like it is losing power because the computer is taking readings off of the O2 sensors to adjust your air fuel ratio. Without a catalytic converter, the sensor is telling the car it is running rich. So the computer in turn will start to pull timing out of the motor, which will make it stall or feel like its losing power. Chips are the expensive way to fix this. A mil eliminator will cost you around $50 to $60 dollars. Good luck!!

when you took off the converter you lost back pressure which will reduce power at low rpms, I'm shocked that taking off a emition component didn't permanently turn on you check engine light, the check engine light is just a light that lights up when a sensor is triggered by a component or a bad sensor, if it is flashing that typically means you engine has a miss fire, but i think the cat conv. was just the tip of the ice berg that's strange if your car ran like a top before you took of the cat, i would defiantly have it checked

you need to have a professional look at the car
I took my catalytic converter off my 87 Grand National to increase the speed- which it did
I had work done by a professional- he replaced the chip at that time

You need the diagnosis codes from the computer. This isn't as hard to do as you might imagine. Go to the auto parts store and buy the workshop manual for your car and it will tell you how to get the codes. (Usually you don't need anything too special to get them)
My gut feeling is oxygen sensor.

A cat went on me in a petroleum automobile, I too lost potential yet i spotted the temperature went proper up into the pink, yet i do not recognize if the unexpected upward push in temperature impacts diesels.

it lost power because you took off the cat converter........duh
sounds like exhaust problems making light come on.......need a new chip maybe? Take it to someone who knows......
