Chip stop working

Chip stop working ? I gather your Caddy has VATS - vehicle anti theft system , with the resistor pellet on the side of the key . It's not the pellet or the key that's bad , inside the lock cylinder there are contacts that read the resistance of the pellet . Most of the time the wires coming out of the ignition lock cylinder break . If you look under the dash near the back of ignition lock cylinder ,at the steering column you should see two wires inside a orange or a yellow sheathing .The wire colors are white , now if you take a ohm meter you can check the resistance of the pellet , stick the key into the lock an turn it to start ,check resistance at those two wires an see if they match the reading you got from the pellet ! If you get no reading one of those wires are broke , at this point you can spend a couple of hundred dollars for a new one or you can spend 50 cents or a dollar at radio shack for a resistor of the same value as the pellet an solder into the wires .

Now if it's not the lock cylinder wires you have other bigger problems , like the anti-theft module .Well then your out of luck because you'll have to take to the dealer or an ASE certified repair shop that can fix this problem .

Go on youtube an check out video on vats bypass , they will show you what I told you about .

Excessive white smoke from tail pipe

White smoke:

White smoke is caused by raw, un-burnt fuel passing into the exhaust stream. Common causes include:
·Incorrect fuel injection timing
·Defective fuel injectors
·Low cylinder compression

Low cylinder compression may be caused by leaking valves, sticking piston rings, ring wear, cylinder wear, or cylinder glaze. When white smoke occurs at cold start and then disappears as the engine warms up, the most common causes are fouling deposits around piston rings and/or cylinder glazing.
Continuous evidence of white smoke indicates a mechanical defect, or incorrect fuel timing.

My 95 neon smokes alot at stop an go when hot :rings ? valve guide or egr?dose not burn that much oil.

ii suggest to look on the valve guide's valve seal.
the smoke (white smoke) from tail end means eating up so much oil.
rings,if you mean piston rings, it's internal and affect the entire performance of the engine.
egr valve - it's only re-directing exhaust gas to the cylinder and be burn again.

Why is white smoke coming from the tailpipe of my 2000 monte carlo?

Is the motor running when you hear this noise ? Is the car using coolant, does the level change ? Is the smoke like normal condensation you see when its cold outside?

The most likely cause of your car producing lots of white smoke from the exhaust is a blown head gasket. The reason it makes so much white smoke is because the leaking head gasket is letting water leak into the cylinders and when combustion happens it actually produces steam which looks like white smoke.

The water comes from the cooling system. There are cooling passages around the combustion cylinders to help them stay cool. The head gasket is just there to make a tight seal between the engine block and the cylinder head.
Unfortunately there is no fast and easy fix to head gasket problems. Some people buy "leak stop" products, but I caution you not to do that. The problem with them is that they contain products that are supposed to stop leaks (which they rarely do) and these products actually get stuck in the radiator and other cooling passages and cause them to become blocked. I would never use a product like this. It is better to just replace the head gasket.

You should take your car to a good mechanic to double check and make sure that is the problem. There are several tests they can do which will confirm that the head gasket is bad if it really is. They can do a cooling system pressure test or a cylinder leak down test to see if it really is bad or not.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I havea daewoo nubira and we replaced the valve cover gasket yesterday , did an oik change and now the engine is smoking white smoke. Try to check to hoses, could not see a leak. Where is the cylinder...

Hello and welcome to FixYa!

The cylinder head is located on the center of the engine. Yes it can be a worn out head gasket or piston rings. If the piston rings are worn out the oil is burnt that's why it emits white smoke. You will need to replace the head gasket and piston rings.

Hope this helps and thank you for using FixYa! Have a good one!

Exhaust smoke upon cold start up

you don`t say what color the smoke is so this is a basic indicator with different colored smoke.if it is white smoke like you would see from any car started up on a cold day then this is normal for cars as the exhaust is hotter than the ambient air temperature.if it is a thick heavy looking white smoke and has a sweet odour then this can indicate a coolant leak into the combustion chamber after sitting overnight such as a bad head gasket,if it is a blue smoke then this indicates oil leaking into the cylinders past the valve seal or valve guides on a cylinder that is on the intake stroke when the motor was shut off,if it was rings it would show only under acceleration,if it is black smoke this indicates an overly rich fuel mixture.

Smokes really bad at the beginning, but after you drive the car for 15 min or so it almost stops. What could that be?

Hi :) What is happening? you say Well when you shut the engine down the oil is hot and it runs by the valve stems because the stem guides are warren out and sits on the piston till you start the engine next time. It take a bit to burn it off then it burns clean till the next time you stop running the engine for any lenght of time.Take it in to the shop and have new valve guides put in it or unbrella seals put on under the valve spring this will stop the oil from leaking past the valve stems. I put a cup of transmission oil/Fluid/Dexron2/3 every time i change my oil to keep my valve seals soft and rubbery and it helps

I have an 1994 Ford Escort 1.8 Diesel Van, As i was driving i have felt that smoke was coming from the exaust and very heavy smoke covered the whole road.So immedietly switched my hazard lights on and...

I will try to answer some of your questions, we do not have many vehicles like yours in this area. If you had white smoke out the tailpipe, that was steam. At least a head gasket is leaking, if not the engine block. You can have the Radiator pressure tested and the test should indicate a leak. There are products which are suppose to seal small leaks internally. Your Diesel has a higher compression ratio than a gas engine, therefore it will be more difficult to seal.

If the smoke was Black or Blue, this is a sign of the Diesel fuel getting past the piston rings. If your Fuelpump Regulator is bad inside the Fuelpump, you will have flooding problems or extreme RPM and a runaway motor. This sounds like your problem. The unused fuel is suppose to return to the fueltank. The valving inside the Regulator or Fuelpump has failed and you can not control RPM. All the fuel is going into the motor.

You need someone to disassemble the components and inspect them for cracks and replace bad parts.

It doesn't have to run hot to be blown. Sounds like you have oil getting into one of the pistons when you make that turn. After a couple of times, it ruins your plugs and that's why you're getting a mis-fire. It sounds to me like the engine itself is blown. The pistons along with the plugs are firing (burning the oil that gets into the cylinder walls. It's time to look into a rebuild.

My 1995 Acura is spewing white smoke even after warm-up. I have tested the oil and have put in more to full capacity. What is causing the problem?

If the smoke is truely white, then I would be looking for a cause of coolant burning in the cylinders. A bad head gasket, cracked head, or block could all cause this. See if your coolant level is low after cool down. If the smoke is a light blue (almost white) then I would look for reasons the engine is burning oil. If your oil level is constantly low without leaks then it is likely you have an issue with piston rings, valve seals, cylinder wear, oil intrusion into pcv system, or some other problem allowing oil into the cylinders.
