yea i posted this in another topic a few days ago, but now ill make this a priority.
i can easily attain 30+ mpg on the highway no problem, but in the city its a consistant 9-10. i dont drive hard on her, and last year i replaced all gaskets/hoses/plugs/wires/filter. i use 93 octane (as i heard anything less the MSD wont run correctly) and my trans was rebuilt 2 years ago. the engine temp indicator stays perfectly over the N (whatever the heck that temp is :dunno: ). could it be my exhaust? im runnin 2 1/4 h-pipe to flowmaster 40's, then 2in from lers back, and have the cats removed. and performance seems adequate.
any help would be appreciated.
Your exhaust is not all out nuts so I would think this is not the cause of your problem. Heck I had a 2.25 system with glasspacks on my old 3.8 and she didn't suffer with city gas mileage. Your good highway mileage would indicate your car has a good tune up and is running properly. Is there a possibility that your car is holding on to first gear too long? Maybe not even using second at all?
i do have that cable that adjustst your shifting points set a little higher than usual, maybe about an 1/8th of an inch. cuz in the "stock" position, when i have her WOT, sumntimes shes shifts to early. so i set that cable a little tighter so she shifts at around 15-18 mph into second gear while cruising, and shifts into 3rd gear around 35-40.
those are just what i think i remember the shifts points are. i havent driven the car sence june :(
doest mean i cant work on it tho :)
The fuel economy in these thing sucks especially if its stock, i mean if its pushing more HP you expect it to be thirsty. right
look for a vacum leak. I had one , but I never bothered with it because the car would idle perfectally. As a matter of fact, my auto teacher said that he never saw a ford(chebby guy, cool as hell though) run so smooth. I got about 7 mpg in the city and about 25 highway. I have been known to punch it when people try to pass me though. After my car died, I decided to tackle the vacum leak. It ended up being the line to the map sensor :brick:. also, I had jet black exaust, and the car always smelled like gas after I floored it.
