bad gas mileage…. and getting worse

[Matthew]

last time i mentioned this i got about 15mpg mind u my daewoo is 26 city 36 highway well since last report its gotten worse i am 1/8 below 1/2 a tank and ive only driven around 92 milees since fill up beginning of this month im not sure what to look for. the ripped hose i replaced didnt change the problem re-gapping plugs didnt fix this gas problem. my air filter is pretty much clean i cleaned the throttle body earlier this year i am really thinking MAF sensor but im not sure what to do i was thinking taking it to autozone tell them i need a scan but i did unplug my maf sensor one day b eginning this month so im not sure if a MAF code will show up from that or if a MAF code does show up im not sure if its because of a bad maf or cuz i unplugged it. i do have a map sensor too im just out of ideas i though ixing that hose and regapping plugs would have fixed it. What should i do?

@grg8888:

I did have a misfire before regapping the plugs… I STILL have a misfire after plug regap but not as bad so it is possible i need new wires too. I cant afford to get the timing fixed if that is the problem nor can i afford to get a new timing belt as doing so would mean well over $600 in repairs over atleast 2 days. The way the engine it is physically easier to pull the engine to replace the CPS or timing belt

1. Not sure what you mean “Running the engine dead cold” Its around 40F this time of year or even colder.
2. I dont think a Temp sensor is a Issue my Temp guage works perfectly.
3. O2 Sensor is a possibility but i dont know if i have more than one.
4. I dont think Exhauset is pluged. When i stated the car after the plug regap the think bellowed thick white smoke for a good two minutes. Ignition timing could be a issue but my Timing Belt is not due for a change yet.
5. Impossible. I have what many Foreign cars have: a gas door that needs to be opened remotely my car is a lever others such as the VW Bug is a button.

Also i have a leaking valve cover the mechanic i took it to to fix the brakes said its common with my engine. I plan on replacing the valve cover gasket anyway assuming i have a socket the proper size to take the nuts off with.[/quote]

The sending unit for the gauge is often NOT the same one the computer uses to determine engine temperature.

Have you had the car scanned for codes yet?
