Exhaust changes causes problems

BINGO. i agree with the above . ebay has a real deal on fuel pump assemblies. but i remember in the bible it talking about one of the fuel pumps turning off as stated above . good catch

If it is a primary fuel pump, would I need to drive it to get the fuel presure or would it show the problem at idel. The reason I ask this is that I am having a hard time finding a fuel presure gauge that has a long enough hose to drive and check it.

Try this first,hold both heater up & down arrow buttons for 5 seconds you will see 00 let them go and just hit the up arrow till you see 16 now hit auto button that will be your engine temp in celcius let your car idle till it hits 75 celcius if it dies then the primary pump is gone.
We have 2 pumps both are on at cold start up @ 169 F secondary shuts off.

Well, all you really need to do is pull the secondary fuel pump fuse and keep a gauge on the rail and key on. Pump should run for about 2-3 seconds and pressure should be between 48-5 psi and hold after the pump stops running.

If you can find just a gauge, and hydraulic hose shop can build you a custom length hose.

I did what you said Pete(pretty cool btw). The car didn't shut off at 75. I decided to take it for a drive with the power key off. It drove like sh**. When I applied the gas, the car shuttered and vibrated for a couple of seconds then smoothed out. My question is even though the car didn't shut off at 75, can the primary fuel pump still not be preforming correctly. Just wanted to see if this rang a bell with anyone. I plan on getting a guage tomorrow and trying what Jeff said to do.

BTW I appreciate everyone's help trying to educate my ignorant a**.

Injectors were all changed in August.
