Yes there can be, depending on which chip you get. Most chips do the same things which is advance the timing and add additional fuel to richen the mixture and adjust the injector pulse width for more output. In most vehicles the manufacture reduces the HP to meet emissions standards and increase efficiency of the car. Example a motor that makes 400 hp may be reduced to 300 for efficiency and fuel economy also for reliability and longevity. I wouldn't go with a no name chip for something as they usually don't do the research a larger company does and most name brand companies will give you the HP and still keep your motor running within normal tolerance without maxing out the vehicle and making it unsafe. Do your research and google the chips and see if any real people are using it and what they have to say. Ebay is a good company to get a deal and variety on the chip. Good luck.

Aren't you way out ahead of yourself there?

Your replacing electronic modules when you
haven't even diagnosed the issues

Do you have any knowledge what so ever about what
your referring to?

Have you hooked the car to a professional scan tool to look
at data pertaining to the various check lights?

First check engine coolant level; if there is too little coolant in the reservoir, you should be alerted to the possibility that there could be a leak somewhere in your car's cooling system. Remove the reservoir cap and add coolant to the Full-Cold line, if a very short time after you refill the coolant reservoir the coolant level is low, there is a leak in your car's cooling system.

Engine coolant is used to heat the heater core and if the vehicle is low on coolant the heater core will stop working. The heater cannot produce heat due to the lack of heat from the engine coolant. Even if the engine is not over heating the coolant level can still be low.

Nest step, inspect Heater Control Valve that is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced. After the repair has been made refill the coolant level and recheck system.

Also, keep in mind that Blower Motor (electrical motor) is used to push air through the heater and air conditioner system, if the Blower Motor fails it will not force air through the system. Ground a test light lead to a good ground source, like a metal brace under the dash, seat mount bolt or under hood brace. Turn the key to the on position; check the fuse in the heater or blower motor fuse panel with a test light. Then lightly touch the service port at the top of the fuse on both sides. If the test light illuminates on both sides of the fuse, the fuse is okay and working properly. If the fuse lights the test light on one side it is blown and needs to be replaced.

Finally, if you are unsure of the location of the heater fuse consult a repair manual. If the fuse condition is OK, position the blower speed to the highest setting. Connect the ground end of the test light to a known ground source. Then probe both ground and power feed wires of the fan motor. The test light should illuminate on only one of the wires (fan motor failed). If the test light illuminates on both wires the ground source has shorted. If neither of the wires illuminate the power source is shorted.

Hope this clues helps; keep us updated.

Unfortunetly Cadillacs have way to many control modules anyway, So I would be able to tell you what this is just by numbers. And Cadillac is stingy with their parts and don't like to release them to parts stores, like chrysler. What is your car doing or not doing, maybe I can tell you what it is from symptoms.

The pistons do not compress like the fronts, they need to be turned to the right as you are pushing them in, like you are screwing them in.

Hello there,
Please follow the steps below to be able to replace the lamp,
  1. Park the vehicle on a level surface. Turn off the engine.
  2. Remove the four pushpins located on the underside of the protective shield on the front of the vehicle. Remove the protective shield from the vehicle.
  3. Reach behind the front bumper area from under the vehicle to access the lamp housing.
  4. Remove the largest bulb socket from the housing by rotating the socket counterclockwise. Disconnect the electrical connector from the bulb by lifting the two plastic clips at the base of the bulb.
  5. Pull the burned-out bulb out. Replace it with a new bulb by pushing the new bulb directly into the socket. Reconnect the electrical connector to the socket. Place the socket back into the housing. Rotate it clockwise to secure it in place.
  6. Reattach the protective shield to the front of the vehicle by reinstalling the pushpins.
Hope this helped. Goodluck Elect_Comp

Power steering systems are actually pretty basic as far as operation, however pain in the **** when it comes to leaks. As read, you said you had leak in what you thought was in your power steering pump, and then found out it was the hi pressure hose that was leaking, Unless your car has some type of fuse that controls it in your fuse panel. (check owners manual, to see if you have a relay type of fuse that controls the electrical circuit that triggers the pump) if so, it could of got blown. However, I believe this is what has happened. When you had a leak in the power steering, you thought it was the pump, so you replaced the pump, which of course pump was probably bad because of lack of fluid circulation with a leak, it instantly will dry out, from high heat of friction from barrings, metal on metal with no fluid. Now, that being said, you put new pump on, but sense the leak was actually off the high pressure hose, means it is highly possible that your new pump, by driving it for even 10 minutes, with the leak of high pressure hose, could of cause new pump to burnout. So, at worse case example, you have burnt up new pump, because of the time you replace the high pressure hose might of already done the damage to the new pump. But, before you go that route of replacing again, the new pump, check all your wire connections that are triggering the pump. Make sure all connections are hooked up good, and making good contact, as even the pump has to have power supply to trigger it, and check to see if inline fuse (if has one) is good and of course as said earlier fuse box to see if as a safety feature, sense would be low on fluid with a leak if it blew the fuse that controls the electronics that go to the pump , make sure it is good. I hope this helps you in the areas to look. Places like AUTO ZONE, can look up your car and let you know for sure if your pump is controlled by a separate fuse and where it would be. Thanks Mike from Fixya
