150k miles, Automatic

Hello all, this is my first post so I'm just going to go ahead and throw this out there and prey to God that somebody responds.

So, where do I start. My problems started a while back when I noticed my car was pulling and realeasing driving at semi-high speeds. To describe this more accurately it felt as if the engine was running super low on gasoline. That feeling of tugging and releasing as the engine is trying to suck fuel that isn't there. Of course an empty tank wasn't my problem. I went ahead and replaced the distributer cap and rotor first off. After I replaced it the problems continued. One day when the car was doing it's normal malfunction routine, there was a complete loss of power and loss of the power steering and then dying altogether. If I'm not mistaken my engine was misfiring and then completely failed. After that it wouldn't start again.

After self-diagonsing my car improperly (as far as I know) I went ahead and changed out the fuel filter as well as the fuel pump. Only to find that my car once again was having misfiring, loss of power and eventually completely died yet again. So... I decide to take it to the mechanic. He informs me that it's putting out codes for the crank position sensor. I end up having him replace it (extremely expensive for part and labor). He then tells me that the camshaft sensor (aka TDC sensor) is putting out a code as well. Just my luck. I end up deciding to replace that as well (also extremely expensive). I end spending around $1200 in sensors (2) and labor. The camshaft sensor is finally replaced. The mechanic tells me the car is running well.

I'm driving to work and it seems to running great but when I get on the interstate I realize at higher speeds (65-80 mph) I am once again feeling the engine lose bits of power and jerk and pull awkwardly. Not as severe as it was, but still quite noticeable.

I have spent an enormous amount of time and money trying to get my car to run smoothly and not leave stranded on the highway. I have replaced the distributor cap and rotor, the TDC (camshaft position sensor), the Crankshaft position sensor, the fuel pump and the fuel filter and I am STILL HAVING THESE PROBLEMS!

Does anyone have any idea of what else could be causing this misfire in my engine. I've also run injector cleaner through a few times a while back. Any feedback would be GREATLY APPRECIATED!

Thanks,
James

 

Just a shot in the dark...failing ecu/ecm?

Catalytic converter clogged?

Ohm check the injectors hot/cold?

 

Read this for some ideas.

Didn't see anything about spark plugs. If they're original they should be replaced.

Not familiar with V6s but the symptom you describe is a classic clogged-EGR-ports symptom on four cylinders. Maybe someone with V6 experience can chime in.

 

I thought that as well,but like you,not familiar what the V6 set up is.

Eric the Car guy on youtube has a video instruction for cleaning it.
