Hey guys.. Im not a new guy here I just forgot and lost my user name... Well I still have my Black GT and ive been driving it alot and I LOVE IT!.. but shes starting to have a developing problem.. i wanna see if any of u stangers have delt with this before...
Well he we go, It has a problem starting on its own like not touching the gas pedal as u shouldnt have to anyways.. Lets say i go into the garage and start it up cold.. it will start fine and run all day.. I could drive 1000 miles in one day and not have one problem. Problem is when I shut it off to lets say get gas then start it up again...It wont start on its own it will whip over and only will fire if i give it like 1/4 throttle.. now if i let off the gas it will imedietly stall... when i drive the car like this its hard to shift cuz the rpms drop so fast like the car dont even try to idle... Before it would do this to me once in a while.. and i would just drive it and it would straighten itself out after like 10-15 miles or min of driving.. Now lately it will do it and not fix itself.. soo im getting worried that whatever is going is only getting worse... I thought it maybe a ignition control mod but these cars dont have it on front of the dist? like the older fox's did.. Or maybe a coil? my buddy said something about the fuel pump ball valve? not sure what that is..... Well hope i didnt confuse you guys.. not very good at typing haha... Any questions just ask... thanks so much!! stang on!!

Cars stock other than a C+L bigger Maf and a cold air intake.. and catless exhaust.. I cleaned the maf with that CFC Maf cleaner.. no difference... i switched Maf's with a friends.. still nothing.. actually been driving the car last couple days.. has not acted up but a couple times when i start it it wont fire up alone i have to give it a tiny bit of pedal. But once its started it stays running on its own...

I had a similar problem recently...about one in a hundred starts she would just crank & not start...then try again after a little pedal & it would start up. Finally it would not start at all, had it towed in to my shop & there it fired right up! We checked many things I was certain it was electrical but they insisted Fuel problems...they found that my fuel press was leaking down as it set sometimes, & sometimes not..ended up changing the fuel pump, & fuel filter & so far it runs great again. I still don't completely trust it yet for a long trip!
