After having the gas line replaced on this vehicle I found the fuel line filter was left out. Now the vehicle bucks and stalls after a short time on the road. However, it will start right away, time after time. Could junk in the gas line be plugging the injector(s)? Thank you, Daryl
I would think the CAT. they tend to clog and make a rattling sound when driving .Seeing you say you did fuel lines witch is another issue with the vehicle in a snowy part of the country they rust out but your fuel pump must be working because who ever replaced the line would have known if the pump was bad they last 10 years then you have to up grade to the new pumps I'm not going to get in to that now.The only other thing it could be is the fuel regulator in witch case just replace all of the injectors and the regulator comes as a unit .But I think its more then likely the CAT is clogged .

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

here are some signs of a bad fuel pressure regulator: the vehicle runs rough, the engine will not start(usually in morning) MANY TIMES ENGINE STARTS BUT STALLS SHORTLY AFTER STARTING. a bad regulator can result in fouled spark plus, and fuel milage will decrease noticeably. the only cure is to replace regulator. what makes it fail usually it gets a tear in the diafram and it cant maintain fuel pressure. hope this helps toolman,

There are NO choke coils on your vehicle, so don't bother looking for something that doesn't exist, just like there is NO carb on your engine. What you have is either a 3.4 or 3.8 liter V-6, sequential multi-port fuel injected engine.
The first thing you should do is replace the fuel filter. This is located underneath your vehicle, in front of the rear suspension. You will need a 10mm socket or wrench to remove the bolt that holds on the mounting bracket for the fuel filter. You will then need to push the fuel line forward towards the filter, while you are pushing in the white plastic retaining clips, then while holding them him, continue to hold the filter with one hand, while pulling back the line with the other, It should easily come off. Repeat for the other line. I recommend this as the first step, because many vehicle owners don't bother to get their fuel filter changed as often as they should. It should be changed at least every 24,000 miles.
Drive the vehicle and see if that took care of the problem. If not, you most likely have a bad fuel pump, which is mounted in the fuel tank, a bad fuel pressure regulator, which is mounted on the fuel rail on the engine, it is usually black with a vacuum line going to the top of it, and you may also have a catalytic converter that is starting to go bad, as once they heat up is usually when the internal grid expands and can begin blocking the exhaust.
This may all seem overwhelming to you, but an easier solution might be for you to take it so a reputable shop and have them run diagnostics on it, with you then bringing home and doing the repair yourself to save on parts and labor. Diagnostic fees could run slightly less than $100, to slightly more than that, but could save you from buying and replacing parts that you don't need.
Hope this helps.
