Hello All! Thank you for welcoming to the world of Mach1club! I am the owner of a 2004 Mach 1 Torch Red (Auto) that I purchased back in 07 at 40k miles and since have raised that number to 134k miles…..The car has not had any serious issues other than having to replace the rear end as the pinion bearing started to scream and howl like hell until 20 mph. Didn’t have to but found another mach rear end for 150$ so might as well and keep the other for parts. The radiator had to be replaced as it became ragged after its life in the Arizona dreaded Heat, which is responsible for the ac compressor dying and being replaced also as the thing is always on!
I have been extremely meticulous with the maintenance on this car and have addressed all concerns as quickly as they have arisen. Always synthetic changed every 4k. Never abused or raced…It was my love and I took care of it like it was significant other!
Now…..This is why I write my thread because im rather baffled at the new problem that this beauty decided to throw at me. The car was a daily driver for a period of years and always saw just freeway time to and from work. I got a 24 mpg consistency for the entire time that it saw the road.…A few months back I parked it in the garage with no problems and its been sitting mostly, driven on Sundays occasionally since I have a Honda that gets 50mpg why not right? Well the Honda took a dump on me for a week while I had to replace a few things…Big surprise the Mach never let me down but my ultra nonviolent Honda couldn’t make the 12 mile trip to work….
Anyways….When driving the Mach I noticed that at slow speeds the motor was sluggish and hesistant… It wouldn’t really produce Mach Power until about 4 thousand rpms as to before it was spunky off the get go…Spinning tires was never a problem from a slow roll. Now I feel that the car could only spin tires if I was holding the brake…No check engine lights… Have never replaced any sensors meaning 02, maf, iac, nothing! The check engine light has never even come on for the car…. Now thus being said I expected for the week of driving to get my 24 or even 22 mpg while driving back and fourth on the freeway to work.. This absolutely did not happen the car produced barely 15 mpg and rolled a measly 200 mpg to a tank running on fumes if it got to 200….I used to get a solid 280 and it never fluctuated! The only difference is before I parked it I worked at a different store and drove the car immediately on the freeway at 70 mph the entire way…. Now im driving to a different store and the car is doing 75 on the freeway the entire way? That wouldn’t justify the decrease by 8 or 9 mpg… Something has to be wrong in this whole equation…
The car has never been tuned except when it rolled off the assembly line and the only mods that have been changed is a roush exhaust when I bought the thing back in 07. I have replaced the spark plugs, fuel filter, water pump, ac compressor, radiator, all hoses, all of the idler pulleys…. Any comments or ideas on where to start would be greatly appreciated! Im thinking maybe start with the 02 sensors, maybe a cat plugged but I don’t smell any sort of oder that would indicate so. Ive been pondering on where to start and don’t want to just go throw money at something replacing a bunch of sensors that happen to be just fine! Thank you for your time and help guys! Hopefully we can get this Beautiful Stang back to where she was!
