so i was told when i got the mustang that it was good on gas... i may just be use to my old toyota but it seems like im at the pumps all the time now.. do's any one else find this happening or is something wrong with my car??
i just bough a 91 mustang and it was getting horrible milage like 15 if i was lucky, so i just replaced the fuel filter( i do this with every car i buy) i check the plugs and they need to be replaced so im doing plugs wires and pcv valve today and ill check the air filter. check all that stuff first youd be amazed at how some of these things could effect you gas milage.......Id love to get 30 miles like some people claim they get
ya that would be so nice im at the pumps ever second day it sucks.... and ya im going to look at all that soon when the weather gets better up here lol u should tell me how it gos after u change every thing
How about calculate your actual milage? It is simple and will tell you if you actually have a problem or not. When my 2.3 was stock, I never got less than about 21mpg and got a best of around 26mpg with an automatic.
If you're getting 14 mpg then why haven't you looked into that? Especially if the check engine light is on? Run the codes and find out what's wrong. Could be O2 sensor, could be something else entirely.
i ran the test threw 4 codes I looked them up and they made no sense and no one could tell me exactly what they were, then again some people at autozone arent too smart ill run em again and post the codes
A code reader is not necessary; the stock Check Engine Light or a test light should be more than adequate for reading codes. Ford EEC-IV trouble codes are all over the internet and in most service manuals. I average 28-31mpg in my '94 Toyota truck and 25-28mpg in my SVO. You should be averaging at least the same with a 2.3 Mustang.
i got a test from autozone a guy left in years ago ill run the codes tomorrow and post them let me know cause i had trouble determining exactly what it was i found websites but still was confused lol i post tomorrow
ok is there a diff way to get these codes i can get to around the 3rd code then eveytime i get lost in the middle of a code and the pauses screw me up anyways this is what i have so far 117 (O,M) ECT sensor is/was low or grounded - ECT 118 (O,M) ECT sensor is/was high or open - ECT 622 (O) Solenoid/circuit failure - shift solenoid 2 - Transmissions the trans was rebuilt rite before i bought the car but any ways theres more codes but i can distiguish the pause from a new code so if someone can help me out let me know
If there is a fault in the ECT circuit, then the ECU is probably not going into closed-loop mode when the engine warms up. That likely accounts for some of your poor fuel economy. On a side note, wth is with those links in the quote of my post?
engine coolent temp sensor circuit. You need to get that checked out, your sensor could be bad or there might be a problem with the wiring, but at any rate, like 65shelbyclone said, the engine is probably stuck in open loop (cold) mode which means it's using more fuel than it should be.
Ok so discard those other number I ran it again and this is what its showing... 136 Injector pulse width higher than expected with BP/BARO sensor 223 Loss of dual plug inhibit control 224 EEC processor/ECA detected coil 1,2,3 or 4 primary circuit fault WTF does all that mean
