Problem with my 2002 Chevy Venture.
3.4L v6 3400.
Question = I stopped for gas a local gas station one Saturday afternoon and filled my van up with
gas. The gas gauge was working at that time I bought the gas. At first I thought it was bad gas. It
has not worked since that day .

It will read full unless is idling then it will go to empty but go back up to full  after I've driven it and
went around a curve or stopped and turned. Then it goes back to full. I've learned to drive without
a gas gauge by using my  mileage and gas purchases every time. So plan on the miles I can drive
on full tank or whatever.

I'd like to solve this problem soon. Being a single parent of 3 children still  living at home I am not
sure I will be able to afford the repairs.
If it is something simple I can do myself I step dad was mechanic  and I learned a lot from
him plus working for a car dealerships over last 9 years has not been a bad thing either.
Added freon, cold on driver side, blows warm on pass side, now all warm

A few other Chevy questions.
Two possibilities. The  most common is a faulty fuel level sensor. This  sensor is attached to the
side of the fuel pump assembly in the fuel tank.  The tank would need to be removed to replace
the sensor. Another  possibility is a corroded connection for the wiring to the fuel pump. There is a
connector under the van that is prone to getting water into the connector  and causing a fuel
gauge problem, and sometimes ABS light. It's just a  matter of unplugging the connector, cleaning
the terminals, and adding a little grease.

Question: This morning I took my daughter to school and the van seemed to be
accelerating, or pulling itself,  on its own.  Once I got home and put it in park the engine
revved up very high and continuously.  I shut it off and then started it up again and it
didn't do it. Any thoughts on what would cause this?  I would like to have some help
information wise before I go to a mechanic.  I am female and not mechanically inclined
by any means.  They usually see me coming! Help please, Sherry.
First thing that is needed is to get the
code scanned from the computer to see if any
are in there. Most of the large national parts store chains will do this for free. If no
codes, or there is a code for a Throttle position Sensor (TPS), then this is a common
problem on this engine. The TPS is most likely the problem.
