Engine Shuts off while driving

kpulido315 · January 25th, 2012, 01:06 PM

Help! Ok i am new to Modded and i am a noob with mustang but i want to learn.

Here is my problem I drive a V6 3.8 2000 and i recently went to a shop to install Long Tube Headers by Pacesetter. I installed them and had to cut off my EGR valve so i did. I had to do this in order for the LT to fit because they did not have EGR. So the shop disconnected it and capped off my EGR vavle.

I got my car back and had to install resignators ( silencers) because it was to loud and i didnt have the cash for super 40s. which I will be installing soon.

My problem is now when i come to a stop i shift out of gear and in Neutral the car's RPMs fall to 0 and the car seems to stall even though it is moving. As the RPMs fall if i accelerate they can rise before it hits 0 but it sounds messed up like its about to stall.

It sounds as if you are at .5 rpm and accelerate not to stall.

P.S

My Exhaust set up is only LT and resignators no cats nor mufflers.

My plan is to remove the resignators and have LTs with O/R H pipe and Super 40s

Please help if you need more info just ask and this is my first post.

Could be your fuel pump.

kpulido315 · January 25th, 2012, 01:09 PM

They didn't touch it could it be anything to do with the header installation. How can i check the Pump

dgt_mustang · January 25th, 2012, 01:14 PM

How is the egr capped off? is it actually secure? could be a bad vacuum leak.

kpulido315 · January 25th, 2012, 01:16 PM

i need to check that out. ALso i havent removed the EGR from the computer could this be a problem??

ReefBlue1994 · January 25th, 2012, 01:17 PM

Sometimes fuel pumps just crap out with age, that happened on my old carb setup, it would drive okay if it was revved but if it got low rpms, for instance at a stoplight, it would die. Your fuel pump should be right by the gas tank, its a simple fix. But check vacuums also. Throwing any codes?

dgt_mustang · January 25th, 2012, 01:22 PM

He would have to be throwing a code if they cut off the EGR, without a tuner to turn it off. I would look in the relevant places first the EGR system, fuel pump does not seem logical to be dead if he is able to start, just has the problem while driving.

ReefBlue1994 · January 25th, 2012, 01:24 PM

is it hard to start at all?usually if something goes wrong after you do something, it has something to do with what you just did, more than likely its soomething to do with your EGR.

kpulido315 · January 25th, 2012, 01:28 PM

no the only time it was hard to start was today after it turned off in like 3rd when i was runing it hard. I had to pump the gas to start it up.

ReefBlue1994 · January 25th, 2012, 01:29 PM

mine was never hard to start up in the morning, but it would be hard to start after it died..(fuel pump issue for me). i would check out what they did with your EGR, then proceed to a fuel pump change if you cant find anything wrong, its a cheap part and a 5 minute fix.

kpulido315 · January 25th, 2012, 01:29 PM

beside today it would restart right up without a problem. Also it has no check engine light and i need a computer to see if any codes are coming up but i think the shop reset the light because they removed the EGR and no light came up.

kpulido315 · January 25th, 2012, 01:31 PM

Yea thats whats going on it is easy start in the Am then today for the first time it wouldnt start up after it died i had to pump the gas to start it up.

dgt_mustang · January 25th, 2012, 01:31 PM

Money is on the EGR system.

ReefBlue1994 · January 25th, 2012, 01:32 PM

slap a fuel pump on it.let me know how it goes,might want to throw some fuel injector cleaner or StaBil in there, ccould have had debree that might have torn up your fuel filter. Ive been saying fuel pump this whole time i meant fuel filter...sorry.

dgt_mustang · January 25th, 2012, 01:33 PM

lol how do you justify fuel pump? when the work was done on the exhaust system DIRECTLY cutting something off?

Reaper_88 · January 25th, 2012, 01:33 PM

Id say take it back to the shop, sounds like they fucked something up

kpulido315 · January 25th, 2012, 01:38 PM

I went by the shop today and they were busy ima go back tomorrow and see its a pain the the #@!$ because i suck at Spanish and communicating is difficult with them..

Ill take a pic of my EGR and show u guys. Do you all have an EGR still ?

And where is the fuel filter, i acess it through the trunk where the pump is

kpulido315 · January 25th, 2012, 01:39 PM

Reaper 88 do u have the SCT tuner did u disable EGR?

dgt_mustang · January 25th, 2012, 01:42 PM

KP, You HAVE to disable your EGR. Its not a choice really. You WILL throw a code, and if this shop was shady like someones backyard then you probably have a huge leak on the system somewhere. Am i invisibile or something lol, why would you waste money on fuel filter? its like 4.00 bucks but still. think about it, your car starts right? you have pressure right? so its getting through.

kpulido315 · January 25th, 2012, 01:46 PM

no man your not invisible lol sorry . No the shop is legit just in the Spanish part of town here in miami. I havent disabled my EGR i need the Tuner for that right?

Could it be a gas leak or exhaust?
