Sounds Like You May Have A Leaking Head gasket Try Some Fix A Gasket Solution From Your Local Auto Part Store. Also Pick Up Some Fuel Additive For Cleaning Your Injectors You'll See A Total Difference. And You Said Fault Lights Are Flashing Or Arent? In The Case That They Are Try What I Suggested Then Reset The Dash Lights By Unhooking The Battery For A Minute Then Plugging It Back In.

My 93 Geo Metro 1 liter 5 speed runs fine but ifvu


6th post wins, with Injector.
the injector can fail for these reasons.
the problem in car lingo, is FLOODING.
and after doing all that did it run? (my other shoe drops)!

1: the 0-rings bad, on side.
2: the injector is bad, it leaks.
3: the ECU injector drive line is failing. (bad ECU)
4: loss of spark always ends in flooding.
5: ECT sensor bad, sending water temp reading to -40C Siberian.
did you get the FLASH codes from the CEL lamp yet, with the
diagnostic jumper , inserted?
6: bad need of tune up, air filter clogged, spark plugs long ago, dead.
do a tuneup every 10 years, or 60k miles and win..
7: Cam belt slipped, low compression for any reasons. again, the 60k mile tune up wins.

when you crank the engine over, with the throttle at wide open throttle
this ACT, cuts all injections. cranking, this covered in the operators
manual, for UN-Flooding all gas engines. and all EFI engines.
and all Suzuki's' (or Geos)

on old dogs like this, i do compression first.
saving a fortune in parts , time and labor, if bad.
do it WOT, wide open throttle.

cheers !

1992 Buick Lesabre Idle Problem/ Bad gas mileage


If there is no "Check Engine" light try a bottle of good injector cleaner in your gas, or cleaning the throat of your throttle body with a good spray cleaner. If the "Check Engine" light comes on then put it on a code scanner and that will point you in the right direction.

My question is about the horrible gas mileage my 94 acura legend has been getting this past year. started eliminating possible causes , oil change, air filter change, air in tires. fuel cleaning...


i don`t quit remember if this year it had fuel injection or not but if it is change the thermostat,as it does affect fuel mileage as it shows the computer that it is running colder than it really is.thus increasing injector on time.i`m presuming this is fuel injected and a bad throttle position sensor(tps) could be causing a problem if it has a maf sensor there could be dirt on the sensor wire that just needs to be cleaned.if its carbureted then the carburetor may need to be rebuilt.

I bought a 92 geo tracker 4x4 thinkin it should get good gas mileage but i only gettin 12mpg but it runs pretty good "Why it not gettin better? "!!!!!!!!!!!


If it's in 4 wheel drive that would definitely decrease the gas mileage. Otherwise it could be a lot of things. It may need a tune up. Could be an EGR valve issue. Throttle body could need to be cleaned a long with the fuel injectors. Make sure your tire pressure is what it should be as well.
Thanks,

Buick regal 92 3.8L Horrible fuel mileage


Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.
