Car Forum / Chevrolet / Chevrolet Trucks / October 2005Drinking Gas
All thoughts welcome. My 1999 K1500 that has a 5.7 liter automatic transmission with a 3:42 rear ratio has just recently started liking gas more than it usually does. I've dropped from an average of 15 mpg to 13 mpg. Just sort of happened over night. The truck has only 67,000 miles on it and other than the sudden gas usage seams to run fine. I'm going to borrow a friends code reader this coming week and see if there are any hints in there. As far as I know the plugs and wires are original, I replaced the cap and rotor at 55,000 miles. I looked at the plugs then and they looked good still. Air and fuel filter was changed within the last 10,000 miles and I looked at the air filter today and it looks good. So in the event that I don't get any codes from the computer can anyone offer some suggestions? Could one of the oxygen sensors be bad and not give a code? I guess that I could have a leaky fuel injector too? Thanks Brian bad O2 sensor will do that if you can get a 'real' scan tool, watch the O2 volts each sensor should switch back and forth, above and below 0.45 volts if one is stuck on the low side, it is telling the ECM that there is a lot of free O2 in the exhaust, and the ECM adds gas > All thoughts welcome. > [quoted text clipped - 14 lines] > Thanks > Brian I assume by a 'real' scan tool you mean a good one?

I honestly would have to do a bit more research on the scientifics of it. But I do know that I used to get worse gas mileage for sure, and was very evident in shorter trips around town. Longer trips tended to be just slightly less, but I chalked it up to having to stop and go when there was a winter accident on the roads.... > That's interesting, I live in Cincinnati Ohio and we have just had the > weather change to cooler weather in the last few weeks.

It seams like you would want a vehicle to get the best mileage for a cleaner overall tailpipe........And also, whats the deal with the vehicle having to run RICHER because of the fuel? The whole thing sounds like an oil company conspiracy. "Ok, it will burn cleaner but it will cost you more per gallon and you will need more of it per mile".....Hmmmmm. Oh, and if your truck's O2 sensor and plugs and fuel filter have 67K on them, change them all (It's due:). > I love my old truck though, 1971 F250, 6 MPG, winter summer, full empty, > It [quoted text clipped - 25 lines] >>> Thanks >>> Brian >> I believe California has some of the worst gas in the country (due >> to EPA regs "Helping" then environment) Get about 12 in the summer, [quoted text clipped - 11 lines] > Oh, and if your truck's O2 sensor and plugs and fuel filter have 67K > on them, change them all (It's due:). plugs, O2 sensors, air cleaner, fan belt, dist cap and rotor, trans fluid, and diff fluid are all less then two years old (15,000 miles max) Thinking about a set of MSD wires... but how much would that really help?

I was just wondering if you moved from another state to cali, would you have to get your vehicle an emission test?

As for moving to CA from another state. The answer is YES any vehicle has to pass testing before it can be registered in CA. I believe they also restrict the year of the vehicles brought in as well. Something like 5 years or newer.. > > Air cleaner and tranny fluid sound like they are due.

Brian ===========Þvil Dude, I would suggest checking the mpg a couple more times before I became overly concerned with the symptom. as fer the code reader and other mentionings in this thread......... Random Thoughts:: A code reader.......reads codes. A good scanner will show you the data. When there are no codes, a code reader is useless. By observing the data values that the computer is showing, you can determine if the sensors and the outputs are operating correctly, and more importantly if the computer is telling your truck to be a gas hog. Regardless of codes existing or not. GM vehicals use "long term" and "short term" logic to adjust fuel delivery, aka Fuel Trim. The values of the two on a scanner should idealy be the same under "perfect" conditions. The values are represented by a percentage. (the same= reeelly, reeelly close) (pefect conditions= nonexistant) A "Drive Cycle" is logged each time the computer is turned on and the factory programed "required" conditions have been met for logging a "complete drive cycle". Eng. temp, tranny temp, mileage, stops, takeoffs, etc...etc..etc.. (drive cycle= each time you run to the liquor store...unless the liquor store is jest down the street, then it's = to each time you go a little further than that) GM computer systems are constently upgrading its command parameters based on drive cycle demand and percieved enviroment and load conditions. (it adds more gas, air, spark, over long periods of time....not jest when it wakes up one morning and yer teenager with the lead foot drives it for a day..what's the chances he's been drive'n it to school fer the last 3 or 4 weeks..hehe) It takes "up to" 50 drive cycles for the computer to make a drastic change in fuel, spark, and air delivery because of percieved changes in the way the trucks being asked to perform. Long-Term fuel trim data would reflect this. (up to 50= i'm not sure, but i'm perty shure) (perty shure= handgrenade close) GM computers will also make immediate short-term changes based on percieved conditions. (short-term fuel trim) Nominal long-term fuel trim is around 128%. Short-term fuel trim should reflect close to that. If....the two values are'nt close, then the computer's trying to make them close, and if it's possible to do so....the values will fall back in line with each other after several drive cycles, and all will be back close to normal again. Gas mileage is directly related to O2 sensor performance. A sluggish O2 sensor does not always set a code. It can be detected in data on a scanner. Can be, not always. A downstream O2 sensor that's reading the same as an upstream O2 sensor will not always set a code.....but by law .... it's suppose to. (but then...it's against the law to smoke Hawain Red-Bud tooooo) Your truck has several temp sensors and engine "load" sensors, and sensors for detecting quanity of air being used. Cold engines need more gas. Your computer "percieves" values given it by sensors. It doesn't know if the values are true.....and does NOT always set a code for sluggish or even bad sensors. Your computer will dump more fuel when it thinks that the engine needs it, once it figures out that what it dumped was to much, it will take a little bit away and things will kinda of level off again. Your symptom could be..... a bad sensor a change in climate a change in fuel grade a change in driver habit a change in engine mechanical condition or.... normal Averaging MPG over several tanks of gas is perty sound way to diagnose an overnight change in MPG.

I did check for codes and there were none, I then drive a few more tanks and the mileage came up to almost what I had been getting in the spring. So I'm starting to speculate that it was either a fuel quality issue or with what you've said a product of the computer or sensors.

I'm somewhat of an amateur Visual Basic programmer and can program PLC computers so I have a great interest in that anyway.

You've had them for six years and that's way too long. A visual inspection won't cut it regarding the wires. Just know that those wires and plugs are cranking hi volts all the time and wear on them is more like metal fatigue than something you would see visually. I change my wires and plugs at least every year and a half or sooner. Also dump a can of fuel injector cleaner into your gas tank four or five times a year.
