Question about Cadillac DTS

2 Answers

Question. I've read about using Sea Foam in my outboard motors to rid them of carbon build up especially effective for removing carbon from the piston rings and crown. Is this product good for my older cars, or would you recommend another product or engine vaccuum.

Works great in all cars, do a compression test before and after and you'll see results.

Rev the car to around 2500 rpms and run it through a vacuum line while the car is running (brake booster line works good) if the car doesnt stall turn it off immediatly and let the car sit for 5 minutes. Restart it and enjoy the smoke show, rev the motor a few times and take it for a drive. I do this in all my cars (Volvo s70, Isuzu Trooper, and Ford Taurus) and do this treatment every oil change.

Most oil additives are not effective and a waste of money, or worse damaging to your engine. Nothing substitues for regular maintenance, oil capacity, and oil weight.

Save your money and be cautious of claims of miracle cures with these products.

My 2010 Jeep Wrangler sport 3.8L engine constantly pings on acceleration or if there is any load on the engine. I think it has something to do with throttle body. Not sure what the issue is.

Try using a higher quality fuel use 93/91 and use the fuel for 2 tank fill's also add a bottle of sea-foam to the tank for the two times you filled with the higher quality fuel. Most likely it's the ethanol in the fuel slowly clogging you're injector's as well carbon build up. The sea-foam will help with this.

.... Robert Grove
johnallen496, when you say it stalls at low speeds and stops, do you mean when slowing down and coming to a stop? does it stall at low speeds while the car is moving with your foot on the pedal just a little like when driving through a parking lot?...

I used the wrong box above, oh well ....

The most common cause of stalling at low speeds, especially idling and decelerating to a stop is carbon buildup. The throttle plates get coated with carbon closing down the opening slightly, this affects the idle speed, causing the engine to stall at idle and coming to a stop.

also carbon builds up in the cylinders and absorbs fuel intended to be burnt, leaning out the mixture and causing rough/low idle and stalling - especially when the engine is cold. Dirty injectors can cause the same symptoms/results

As a maintenance routine It's good to have the throttle plates cleaned and perform a top engine de-carbon treatment, and fuel injection service in more severe cases

Sea Foam makes a spray that works great for minor de-carbon service, just spay it into the throttle plates while it is running, one to two cans will do, add a can of Sea Foam or Techron to the gas tank each time you fill up for the next few tank full's.

If you still have problems sek out a qualified professional

Good luck!

Why is my fuel light on but my tank is full?

Does the gauge read full? If not, change the fuel pump assembly. The level sensor on the assembly isn't working. Check engine light on? If so, it may be telling you the level sensor is not functioning.

I have had American behicles that had level sensor problems and was remedied by adding Sea Foam, a full bottle, to the fuel. Corrosion build up from using cheap gasolines cause conductive interference and the Sea Foam will dissolve it. It may work, may not.

If after 150 miles of adding it and you still have the problem, replace the fuel pump assembly or just the level sensor if available from KIA Motors. Either way, the tank will have to be removed from the van.

Engine knocks at cold startup. knocks more under load. lasts about 5 minutes till warm. Dealer said: 1. " They all do that. 2. Piston Slap, don't worry. 3. Valve train slow to warm up in this...

I bought my wife a Lex and she also experienced the SAME problem. It is TRUE that that's one of the engine's characteristc's,but it can be corrected. These are the step's that i took.

(1) First step is to change the oil and filter if you HAVE NOT done so lately. (Get a GOOD filter(Fram or Puralator) and oil ( I use ONLY Castrol).

(2) Get a 12oz bottle of Sea Foam(insist on ONLY Sea Foam,because auto part's store's will try to sell you what's on sale. I KNOW that Sea Foam work's). Pour HALF of the bottle in your oil and the other half in the gas tank(Make sure that you have atleast a half of a tank of gas BEFORE you pour in the Sea Foam). The Sea foam will clean your engine internally to promote better oil flow,especially at cold start up when ou need it the most. When added to gas it act's as an upper engine cleaner to get rid of carbon build up in your Intake and EGR Valve which can cause the symtom's that you describe.

(3) Protect your internal engine part's during cold start wam up's by pouring in a bottle of Slick 50 AFTER you do the recommended oil change.

(4) Lastly, use NOTHING but 93 octane gas in you vehicle.

If you do ALL of these step's, you should notice the difference.

Is there a way to change the spark plugs in a 5.4 without the danger of breaking them in the head? I understand it is a carbon buildup on the plugs in the com. chamber

Trust me, no matter what you do, the danger exists. Ford says to crack the plugs loose not mere than 1/4 turn and spray penetrating oil into the spark plug holes and let it soak for at least an hour. Then, carefully work the plug back and forth until it comes out. The problem that I have experienced is that the cracking 1/4 turn is what breaks the "blankety-blank" things. Once they are broken, you are done without the special tools needed to extract the thread part of the plug, then go fishing for the lower end which just fell down into the cylinder. This is definitely one of Fords WORST ideas.
I highly recommend that you do not try this at home!

Wont start when warm without pumpin gas, and engine revving to high

A high rev problem is due to either carbon build up in the iac passage's not letting the iac close to normal idle or the iac is just bad and stuck in that position.

iac= idle air control solenoid

Inside the throttle body intake is a butterfly and just above that is a small opening that the iac uses to move air past the butterfly and this sometimes gets plugged with carbon build up so spray some carb cleaner down through the passage,and sometimes you have to remove the 4 bolts and take the throttle body off to clean them out.

Saturns are known for carbon problems,and they are hard on egr systems,I recommend using sea foam a couple times a year to help fight the carbon build up,just follow the direction and use it in the fuel and vaccum lines as directed but do it on a warm engine and let sit for a couple hours so the sea foam has time to loosen the carbon

Ticking in the motor

Sounds like you have a lifter that is sticking. Purchase a can of Seafoam Motor Treatment at Advance Auto Parts, Walmart, and many other suppliers. I have used this product many times and it is fantastic. This is not a motor treatment such as some of the others you see advertised to improve mileage or stop oil burning. This is a legit product that many mechanics trust. To clean lifters, add 1½ oz. Sea Foam to each quart of oil. Sea Foam will slowly re-liquefy the old oil varnish residue that builds up on lifters and prevents them from functioning normally. This process can be done as part of a pre service cleaning by adding the Sea Foam to the oil at least 30 miles before the next oil change interval. OR it can be done as a preventative maintenance process without changing the oil. You can leave Sea Foam in the oil indefinitely as long as the oil is clean. The addition of a high-detergent oil like Sea Foam may cause the oil to become dirty faster than normal as buildup oil residue and contamination are cleaned. Check the oil at regular intervals and when it gets dirty, change it.

2001 cavalier sputters at high spee

This is an obstructed fuel delivery system. i recommend replacing the fuel filter and pump as well. replace the air filter also.I suggest using an additive like sea foam to flush the fuel lines and, clean them out. This treatment will scrub the intake as well, getting rid of carbon build up.

Code P0506, Idle control system RPM low

It's common that you get a lot of carbon build up at the base of the throttle body. Give it a good spray cleaning with injector cleaner and dry it with a hair dryer. If you find it still to dirty, you can try it again with a second can or if you can try using Sea Foam that you can buy at an auto parts store like Auto Zone. The Sea foam will clean out the carbon but also create a lot of smoke.
When i say lot's of smoke, just do a search on You Tube for Sea Foam. Good luck and hope this helps.
