Idles rough once it starts to warm up and cuts off after it gets warm.

scan for codes and check fuel pressure first then check for a vacuum leak

If its getting to much fuel then how i go about fixing it?

check your pressure first not "that it's getting to much fuel". it can either be a pump or regulator. unless you decide to use the shotgun approach and spend money unnecessarily on parts that may not fix it. You've done that already. fp should be 30-45 psi engine running or 35-45 key on engine off

The fuel pressure regulator is mounted on the fuel rail isn't it? Has 3 bolts and the vacuum hose running from it the intake right?

yes

Okay. I just wanted to make sure. Thank you. I will try an see if this is the problem after i check the codes.

Fuel pressure is fine and i changed the fuel regulator and checked for vacuum leaks and there is no leaks. What else could it be?

fuel pressure is fine? what is fine? how much psi? scan for codes as well.it cold be leaky injectors but you need to eliminate everything else

Its has around 32 psi when its off and around about 36 with key on.

originally I said scan for codes so do that and look at spark plugs if wet throw them away and replace them it may start like that. it can also be bad injectorsbut I dont' have any specs for them to check for resistance. Other than that not seeing this vehicle I couldn't tell ya what else to do.

Ok. I ran the code check and it kept coming back to egr low voltages so i replace the egr vacuum thing and then the egr valve but after looking at the plug for the voltages on the egr i noticed a ground wire was loose so i pushed it in and it seems to be doing a little better. As it was throwing up codes for that it also throw up system pass code. It never the whole time throw up the O2sensor code like i thought it would cause of s little leak around it.
