Vane air flow (VAF) units are a common failure on these cars. It is the the sensor mounted inline on your intake tube that is aluminum and black plastic with a round twist plug. If you unplug it an it runs better that is most likely your culprit. The gentleman above is on the right track. Intake boot cracks/failures are quite common on these older cars too as are the EGR tubes/hoses - listen for air leaks/sucking noises.
The idle air sensor (IAC), made by Bosch looks like a small coke can with two tubes and a plug going to it. Sometimes they are hard to find/hidden under intake. They do go bad, but can usually be cleaned with car/brake cleaner. The internals should rotate; they are just an oscillating valve that regulates extra air to the intake.
You never said it it runs fine once it us up and going. If it does, it could also be a oxygen sensor. You should really consider having the codes read... it really shortens the list of parts to check!
Last month, my wife complained of high gas usage as well. I suddenly remembered that I had forgotten to change the air filter the last time I did the oil change. It had been over 5 months since I'd put a new one in. So, we got a new air filter, and monitored the usage, and it was back to normal again. Maybe try this?
rubber pipe , its at the back under the pollen filter , comes as a
double pipe one fat one thin , fat one is for air flow , thin one water ,
both for cooling the engine. The fat one was actually split , causing
my engine to idle bad , so i replaced the part , engine idle is fine but
now i gt that noise , and i get air suction when i take oil dipstick
out while engine is running , so i am guessing something is not right
but dk what
hello right have u had service done recently may be sh**y plugs check oil lvls and get her running with someone reving and unplug air flow meter se wht happens if theres no change in engine noise it prop tht otherwise take off air intake pipes etc check for blockages (very rare) i can also suggest common fault is pipe from air flow meter to the engine suffers dramaticly from lil cracks and alsorts check tht over completely and the hoses beneath it try all tht first if you dnt have any luck thn start thinking fuel filter alot of crappy fuel about nowadays but i rekon its your pipes either crackes of poped off let me know how ya get on
try checking the fuel filters for dirt, clean if necessary! i don't know if this is the exact copy of the idle adjustment of your car the idle adjustment screw is on the carburator area. nearor just below the air filter.
