Thanks for clearing that up makes sense. I am going to change out my coil packs to see if that helps the issue. Would removing the IMRC contribute to the loss of 1 to 2 lb of boost since it can flow more?

How does boost affect Fuel pressure? I have a 6lb kit but for some reason it is only making about 4lb.

I am running an Autometer Fuel Pressure gauge off the fuel rail. I pulled the plugs out and they have carbon build up on them. unless there is a problem with the ignition side wouldn't it be running rich? would the car be running well other than WOT if there is an ignition problem? I...

Did some Research and came across this. Since I swapped the Cobra motor into the GT and did not realize the fuel pump was different flow capacity, would this have an affect on it? Wouldn't that be making it lean if anything rather than rich? What would swapping a better fuel pump do to...

I am running 20% and I thought of this while doing a road test so I put it to 10% but still doing the same thing. Then tried 0% and same thing. Could there be a problem with the MAF? I talked to Kenne Bell about the Air pump code and they said it will have no effect on the drive ability...

So I changed the spark plugs to the e3 plugs, old ones had some carbon build up. cleaned the IAC, MAF, and Throttle Body. She Seems to be running smoother and starting better. She still has a problem at WOT at High RPMs I talked to Kenne Bell and they say it would still be running rich. It...

Is there any difference in the fuel system between the '96 GT and Cobra? Mainly talking about what is in the tank. Thanks in advance.

Thanks for all the help guys, I am going to take a look at the fuel pump and see about deleting the PPRV, yes I will change the fuel filter at the same time and yes I do change it regularly. I will also Clean the IAC to see if that helps. Is there any difference in the fuel system between the...

I'm not trying to insult him I'm making sure everyone knows what app I have so that it wont get off topic like it has when I tried getting this problem solved prior times. I hope he did not take offense to this and If so I do apologize.

Well It is well known that it is NOT a GT Engine, Cobra's had 32V and an Air injection system which is what is in the car.

the only code I have is for the air injection emissions which I don't have

key first time Fuel at 25psi key second time Fuel at 40psi "I just went to check it and it only needed one key on this time to get to 40psi, Most of the time I double key it if it has been sitting for a while" once started idles around 40psi step on gas fuel goes up to 50psi and engine...

When starting I turn the key on and off twice to build pressure. Don't see any leaks around injectors. still stutters. well more like it starts then chugs to a stop. start it again and it idles fine but if you give it gas it stutters. The PCM has the Kenne Bell Tune so not an issue there...

Wires are new Ford Racing 9mm, No Codes, Do have fuel pressure gauge. When starting I turn key on and off twice to build pressure.

When starting car after it has cooled down like over night it has a hard time staying started the first time unless I flick the gas. Then stutter while under hard acceleration until up to operating temp. Note the temp outside is avg 70F to 90F. Also at any time at WOT I need to play with the...

I have a 1996 Mustang Cobra with Kenne Bell, Headers, exhaust, ect. I am looking to buy a tuning software that can actually be tuned. Not just plug in what kind of headers i have, what kind of intake. I am looking for one that I am in control. Does anyone have any sugestions? Thanks...

96' GT 5sp Stock with 125,000 mi It takes about 2 sec longer to start than it should. It runs fine and the fuel pump sounds to be priming alright. What could be the main factor behind these long starts? Could it be the fuel pump? Starter? Coil packs? I am curious because the car drive...

It just blinks like it is in "theft" mode. For some reason my car will start and then shut off with an un coded key instead of not starting at all.

Ok so here's the thing, I am using copper plugs and they have fouled out on me before so I was quick to think that that was the case! I looked at my cluster and the THEFT LIGHT is flashing. The car is Obviously trying to stop but it is still sputtering. I am trying to make it to the parts...

Well I finally got to go home on leave to do some work to my car and take some pictures. That has come and gone because now I am leaving for Iraq in a few days! Then again what makes driving my car that much more fun is storing it and the anticipation of getting it back out! I just got some...
