Well got the car started and now a new problem. When I drive the car will lose gas and choke spit and sputter almost cut off and then WHAM it starts going again and will yank you back in the seat. Only does that every now and then not all of the time. Then last night on the way home I go around a turn and car cuts off. I get it started but it want idle so I have to keep RPM up around 1,500 rpm to stay running. I was one block from home so we just coasted into the garage. Now this morning starts just fine and idle is fine.
I think it's my fuel pump but I really have no idea.

Throwing any codes ?

Does sound like a fuel supply problem. Fuel filter OK ? Any recent fillups/fuel adds ?

It's throwing a MAF code. I changed the fuel filter/Maf/Air filter and still does it.

I'm going to check the water gage and look for a hose off somewhere. I will post back what I find.

What's really weird is that I am having this exact same problem the past day or two. My first thought was vacuum hose and checked all those last night. None seem to be an issue. Just started it up earlier this evening and it was running just fine. This monster's gotta mind of its own I tell ya.

Drove my all day and no problem. Come home and take wife to the store and it did it again, so I told my wife that it's here fault! I can't find anything wrong with the car so it seems like the thing to do.

Were is the crank sensor? I'll replace that as well and see if that works. I had someone else tell me that as well.
