Engine service light ON after using 3M Fuel system tune-up kit I followed the direction in the video. The product seem to work as I see the dense white smoke after following the steps. However, the Engine Service light is ON now. I just changed my engine oil a week ago. Does anyone know how to take care of this engine service light?

Disconnect your battery cable for about 30 seconds and reconnect it then drive normally. Hopefully the light will stay out and depending on your car type it may not have to do too much re-learning. Check your manual first to see what it says you have to re-set after a dead battery.

The CEL light is usually not a serious issue. The emissions control on your car is the usual suspect. When you cleaned your fuel system it set off your emissions due to all the excess gunk and dirty fuel being exhausted at once, thus the reason you saw dense white smoke from your tailpipe. In approximately 3-4 separate engine startups, the emissions will reset to indicate normal readings to the CEL. If the CEL doesn't clear in a week, get it scanned at any autopart store, don't go to a mechanic until needed.

The CEL light on is because of the "junk" coming of the engine parts. Should clear up in 100 - 200 miles.....

I know I'm really late on this conversation but as an alternative to the answer from Bill L. is to take your vehicle to an Autozone or O'Reilly's or some other auto parts store that will connect a code-reader to your vehicle for free, make sure the code is from the O2 sensor and have them clear it. Disconnecting the battery on newer cars can be a bigger pain because of all the advanced electronics. At the very least it will save you from having to reset all your radio presets!

Yep if it ain't broke.......screw around with it till it is!!!Like momma used to say,"You wont be happy 'til you break it".Leave well enuf alone!

It's why I'm suspect of these kits and products. Yes you may be cleaning out the gunk but that gunk has to go somewhere. So, out your exhaust manifold moving downstream to coat $100 oxygen sensors and clog $1000 catalytic convertors.

Run your car hard and get the RPMs up after this treatment. If it doesnt clear up after 200miles, go to a parts store and have them clear the code.

Overall my mileage dropped about the same amount ~15% that the performance increased according to the run on the dyno after the installation. I put a new higher flowing air cleaner, and exhaust system at the same time. Most of the decrease mileage is caused by me using the extra power. If I cruise gently, I get close to the same mileage. There should be a slight decrease from the fact that H-D runs the engine leaner than what is good practice for keeping the engine from overheating. At least that is the story that I have been told by several people. The Cobra tends to add a bit more fuel to the mix which is probably worse for emissions and mileage, but better for engine life.

It could be the fuel filter. The manual suggests you change it yearly or after 50 hours of use. I had this issue and that is what it was.

our engine is a Kohler 15.5 HP - might be a different carb, but I would bet the fuel shut-off is the same. I replaced ours because the engine would die after 10 minutes or so. 10-15 minutes later it would start and run for another 10 minutes and die. Turns out this was not the problem - it was the ignition module (provides spark to spark plug) Replaced that and it now runs fine. If you really think its a carb problem - just order a new carb and don't do a rebuild kit. Been there done that. Installed new carb and it now runs better than it ever has. 10 minute change out. With a new carb it comes complete with the fuel shut-off. Gas with ethanol seems to eat the diaphragm's up. our engine is a Kohler 15.5 HP - might be a different carb, but I would bet the fuel shut-off is the same.

Changing to this EFI system will remove the leaks causing the gas smell. Additionally, you will see fast starts, better throttle response, increased power, and better fuel efficiency. We have it in stock and ready to ship. Thanks!

Your oem sensor under normal conditions will give you 3+ years of service. Signs of degradation are: a decrease in the amount of km per full tank of fuel; the engine with give a rough idle similar to that which is gives when then AC is turned on (this is due to an inconsistent signal returning to the ecu resulting in either a richer or leaner mixture) ; if you have a a/f Guage installed you will see the Guage give a sporadic reading. The reading will fluctuate a lot and you may even feel the vehicle feel like it's losing power. If you rpm is behaving as you describe it can also be a result of your distributor.

If the fuel has gone bad then you need to drain and replace with fresh fuel. That point on I would recommend using Lucas to keep the rest of the fuel system clean.

Hello there! I'm sorry to say (or is it good?) that we haven't had the Filter in that long to have to Clean it yet? I believe, but am not sure, that K&N; have their own type of Oil to Re-oil? Not for sure though? Sorry I couldn't be more help. Really like the Filter though! Seems to really help in the Midrange of the Power-band. Good luck! :0)

Yes, the battery appears to be working now and I am seeing the goodbye image when I shut off my ignition. It looks like the same unit I sent back. How did you fix it?

I wait till my tank is almost empty than put cleaner in, I than run it up the freeway HARD to clear out as much carbon as I can then stop & fill up. My vehicle is running GREAT again by the time I get to the gas station. Hope this helps. Best Fuel System cleaner on the market well worth the money. Mechanics must hate thus product!

The instructions recommend you shut off the gas and run the motor out of gas each time you shut it off.. They really know what \they arte talking about.. On start up it always starts second-third pull. Runs great and is economical on fuel

i would return it as mine does not do that and runs fine on either fuel! john hundley ps i dis agree with the othe answer as i do not believe that you should be a mechanic on a new item

I would check for spark first, a simple test for this would be unscrewing the spark plug while connected the putting the against a piece of metal if you see sparks consistently then the coil is good and it most likely is a fuel delivery problem. This one way work I would mesaure and make sure the screw holes line up otherwise you may need to machine new holes. hope this helps.

I was afraid of the same thing before I installed mine, but since I have installed it I haven't had any hassle from the dealership when I go in for routine maintenance. It could be a factor if the engine fails in the future due to some unrelated problem. Hope this helps

Haven't used it recently, but I do recall there is a quirk with the pilot light... you have to hold it down for a longer amount of time than you would think. Especially after starting a new tank of gas.Sorry I'm not more clear on this... but it is not anything 'wrong' with it. Maybe you can read more about the pilot light... I recall having to hold it and count to 20. My memory is foggy. Hope someone gives you a better answer!!

I do not know for sure. Remove the fuel filter and try. If it fixes the problem then you have a bad fuel filter. Maybe something is stuck in the fuel line going in to the carburetor. I used it to bypass my weed trimmer once to bypass the bad original priming system and it worked. I never seen this primer bulb installed in a weed trimmer before. If nothing fixes the problem You might have a defective primer bulb

I have had the same problem and I found out it happens the most when the fuel canister if full. Make sure to hole the canister so the threads are up as if the canister is setting on the ground when you thread it on. thread on slowly until you feel it getting tight then quickly turn it on to avoid excess spay. You will notice the difference that very little if any comes out.
