1999 ford mustange v6

That's very strange - my car has the exact same problem.

Whenever I push the accelerator down to the floor, it really surges. Then, when I let up off of the accelerator, it slows down - until I push the accelerator back down, and then it surges again.

Weird.

are you using the accelerator peddle or the surge peddle?

Wait. You're confusing me. I've only got two feet, and one is reserved for the brake pedal at all times. I like to rest my foot there, so my brake lights are on all the time. That lets all the other drivers behind me know that I might be stopping. Some time.

why does it start to sputter like it aint geting fuel but it has a new fuel pump. can it be the throtle body?

Have you checked the fuel filter?

i have a new fuel filter also it seems like if you hold the pedal down it does just go to spitting and sputting until you let go of the pedal then it takes off.

It's probably a bad sput sensor. Check the voltage drop across the sensor with the KOEO. Should see about 6 volts.

for get the sput sensosr for now, but clean the air throttle bypass with carb cleaner real good.

You mean the Idle Air Control valve??

yea thatsssssit. Always forget the name of it,

could be they didn't polarize the new fuel filter when they put it in......or if it's one of those oil bath air filters, they might not have put oil in it first.

would help to know how many miles on the car, what else has been done to it if its high miles, etc.

but I think this whole thing is a joke since you say it's a V6 and you have problems when you take off FAST.

to: snipped-for-privacy@webtv.net (its from click) the mustang has about 122000 miles on the motor. but it doesn;t just have trouble taking off fast,it also has the same problem when you try to get passing gear it starts to go bup bup bup, until you let off the excelarator,then it will go back to normal.it didnt have a oil air filter when i got the car. and the fuel filter was new. if you have any more ideas i would sure like to hear them....

I am just wondering if there is a mechanic out there with a verry good answer to my car problemwith the 1999 ford mustang v6 3.8. I have put a new fuelpump,new mass air flow sensor cleaned out the idle air control valve,replaced the air cleaner. The problem is when you take off fast , or try to get passing gear it starts to act up by going bup bup bup, until you let off the gas throttle or (pedal).then it goes fine it will go fast as long as you dont push the pedal or try to pass any cars. any sugestions anyone?

I speakthis. Did replacethe fuelfilter?
