First I was sitting in my car in park talking on the phone for about an 1/2 hr and it started idleing a little rough. I shut the vehicle off and the next morning when I cranked the vehicle it was running rough again.

Then I noticed it was using a lot of gas and that tank lasted about 1/2 as usual.

Then about a week later as I was driving the vehicle just went dead I sat on the side of the road for about 5 min and then it cranked and this has happend several times so I got some one to run a dignostic and I got an error code P1456.

I have never changed the fuel filter and I have not done a tune up in 60K.

I am going to do a tune up but do you have any other suggestions.
I can't afford to get a mechanic at this point in my life and I am unable to drive because in the DC area
this is too dangerous.

I need my car for work so any help you can provide would be appreciated.

Hi Highpockets,

DTC P1456 & DTC P1457 - EVAP CONTROL SYSTEM LEAK DETECTED
1. If either DTC P1456 or DTC P1457 is indicated, check for:

A faulty fuel filler cap.
Proper vacuum connections.
Fuel tank leak.
EVAP control canister vent shut valve malfunction.
EVAP control canister vent shut valve circuit malfunction.
EVAP purge control solenoid valve malfunction.
EVAP purge control solenoid valve circuit malfunction.
EVAP by-pass solenoid valve malfunction.
EVAP by-pass solenoid valve circuit malfunction.
Fuel tank pressure sensor malfunction.
Fuel tank pressure sensor circuit malfunction.
EVAP control canister malfunction.

It could be the reason the fuel consumption has increased.

HARD TO START

Check the battery.
Check fuel pressure.
Check ignition wires, ignition coil and Ignition Control Module (ICM).
Check for low engine compression.
Check for intake system air leaks.
Check for contaminated fuel.
Check Manifold Absolute Pressure (MAP) sensor. Check Barometric Pressure (BARO) sensor.
Check Evaporative Emission (EVAP) control system.

The EVAP system should be the cause of both problems.
