Default Need Help..

Driving my GS down the street and all of a sudden the engine starts to cut out...i try giving it more gas and it only seems to exacerbate the problem. Eventually it cuts out, i start it and it'll idle for about a minute or so and if i try to rev it up its really hesitant and just wants to shut off. Now it won't even turn over..any help here??? I think it's a fuel problem of some kind..maybe a fuel filter or pump.

thanks in advance

_Tom

Wait...did you replace the TPS without adjusting it to OEM specs?

In ethics, it could be anything. Asking a vague question like this is not gonna get you no where. I suggest you take it to a mechanic and stop the guessing game. Just saying.

Nope, not at all. There's two screws on the side that you loosen so you can twist the TPS and adjust it. It has to be spot on.
