Hey guys:

Got a question for you:

Every now and then, I encounter a problem where I try to start the car, but IF I can get it cranked over, it idles very rough, and dies out if I try to give it any throttle.

Fuel Pressure, Battery Voltage, and Oil Pressure are all OK according to my dash gauges.

Anyone else ever encountered this and have any ideas?

I'm thinking dead coil or spark plug?

Right now she's parked in front of my garage and I can't even keep her running long enough to pull her into the garage

 

you have a fuel pressure guage?, cause I'd say it sounds lika a fuel pump....Who knows though....I had an oxygen sensor go out on my focus and it did something very close to what you are experiancing....take it it and have it looked at....something is definatley wrong.

 

Yes, something is definitely wrong lol. No doubt about that. I'm wondering if the dealer can send a guy to my house or if I'll have to call a flatbed to take it there $$$$$$$$

 

It's not throwing any trouble codes (won't even get to an RPM high enough that the CEL would come on), so there's nothing to read or clear w/ the SCT :hs:

 

Did you get any part of the engine wet sounds like what happened to me once ?

 

one of the coils got some water sarted to arc out I guess and blew so when they tested them and found one gone bad and replaced it was off to the races.

 

Or try to reload your original tune back in place , maybe do that first !

 

Go back to the stock intake and tune and see what happens, before you spend money on hauling it up to the dealer.

 

Doesn't Ford Roadside assistance pay for the tow?

 

Mustang operational

Took out the MAF (looked super-clean ), put it back, re-flashed to stock, the car started, idled ****ty as hell for a minute then went back to normal...pulled the car back into the garage and re-flashed back to the 91 octane tune...**** started right up and idled fine Progressive revs to 4000RPM saw no issues or hiccups

Going to have to call Brenspeed on Monday and talk to their tuner, and set up an appointment at Ford to have my O2 sensors, Coil Packs, and Fuel Pump/Filter looked at

 

Great News ! glad its workin
