A malfunction indicator lamp (MIL), also known as a check engine light, is a tell-tale to indicate malfunction of a computerized engine management system. It is found on the instrument panel of most automobiles. When illuminated, it is typically either an amber or red color. On vehicles equipped with OBD-II, the light has two stages: steady (indicating a minor fault such as a loose gas cap or failing oxygen sensor) and flashing (indicating a severe fault, that could potentially damage the catalytic converter if left uncorrected for an extended period). When the MIL is lit, the engine control unit stores a fault code related to the malfunction, which can be retrieved with a scan tool and used for further diagnosis. The malfunction indicator lamp usually bears the legend check engine, service engine soon, or a pictogram of an engine. In the United States, specific functions are required of the MIL by EPA regulations.[1]
False triggeringHigher amounts of methanol/ethanol (or other additives) than the engine is equipped to handle may trigger the MIL(see E85). These burn differently from gasoline, and the EFI system may mistakenly interpret the oxygen sensor's readings as being incorrect. Oxygenated gasoline can cause this false triggering in early EFI systems.[citation needed]
Then when I would accelerate I would get some light bucking. Also seems like my temperture is going up just slightly. Usually stays right at the mid point and not it is going up 3-4 notches
I'd LOVE to help, but every time I read one of your posts, my mind goes to the gutter: Seriously, is there a gas additive that you could use?
e85 is not gas. Drain that crap from your tank or dillute it with 93 octane.
How full is your tank?Easiest thing to do is drain the tank and start with fresh gas. Find a local garage to do it for you... they probably won't change more than half an hour of labor. Or you could do it yourself. Your tank should have a drain plug (bolt) on the bottom somewhere (or you could siphon it into the neighbor's garden ).
Do you have a portable gas can? Go buy a gallon of fresh gas.1/4 tank is about 3-4 gallons. I would siphon or drain the tank and start over.
Yes. But that's no fun.
It should if you have a very small amount in the tank.
I just wondered.I never put the wrong fuel in a motor vehicle--I watch what I do--and so this is an experience I haven't had.But to carry this on a little further, what if Gina had put diesel in there? Would that work, putting in the appropriate fuel so as to thin out the diesel?One doesn't think the motor would work so well, but that ultimately the diesel would be gone, and everything back to normal.
I didn't put the wrong fuel in there!! I have bought gas there lots of times. I got regular unleaded.
And you got the gas cap back on correctly? Sometimes you don't get the cap on just right and the vehicle gets all 'I am so unhappy". Just another thought. Bad gas has been known to happen even if it is the right gas. Alcohol (e85) has a tendency to attract water. I vote try some fresh gas. I don't think I would get all concerned about draining the existing if you only have 1/4 tank. You could also go bat those long lashes at the local dealer and ask him to read the computer code or find a friend with a reader. Depending on the vehicle they use to sell a key device that would let you do it yourself by counting the flashes of the CEL o MIL or whatever they are calling the idiot light now a days.
EWWWW Autozone will do it for free and I don't have to bat or bounce anything
Wanna Tiger in your tank? I don't think you can get "free reads" at Autozone, at least not here or I'd suggest that. The dealers filed a class action lawsuit to prevent it, so now you have to 1. buy one. 2. know someone with a reader, or 3. go to the dealer who will be MORE than happy to turn off the light for $29.99, then tell you what it said and how to fix it. How convenient.
