The car feels as if it wants to die or a miss fire, When checked at repair shop they say its starving for fuel and the codes refer to lean 1 &2. I also started haveing a problem with filling up about the same time the nozzle keeps shutting off every few gallons.

Fuel Air sensor is the most likely cause, but can be other things.

Change the #1 fuel injector to #2 and #2 to #1 position.If the miss fire code changes to #2 cyl that fuel injector may need to be changed.I would try that first before spending $$$

with out a doutb its the o2 sensors. replace them and all codes will go away.

check fuel pressure if low probably [one of the most common problems] need fuel filter -others need tune up -egr valve carboning up [clogging]-- carb needs adjustment/cleaning-air filter clogging -feel and listen to exhaust if sounds like starving or little air coming thru possible cat clogging

Use the codes you have to diagnose

Could be a rich condition & computer
is driving fuel trim lean-thus the code

Could be a bad O2 Sensor stuck lean

Could be a vacuum leak & lean codition
as a result

Need a repair shop or lots of studying
if your going to resolve & you can

A few things to check:
1. A bad intake manifold gasket
2. A missing O ring gasket between the air filter cover & the MAF sensor.
3. A dirty fuel filter.

What's the code? P0171 & P0174 would indicate a vacuum leak. P0171 could be the MAF sensor. Good luck, I'm still fixing all my Verona's annoying "quirks".

P0171 - System to Lean (Bank 1)
P0174 - System to Lean (Bank 2) Lack of fuel or too much air - unmetered air after the mass air flow sensor ! vacuumn leak . Not enough fuel - low fuel pressure , clogged injectors .
P0171 - System to Lean (Bank 1) The Adaptive Fuel Strategy continuously monitors fuel delivery hardware. The test fails when the adaptive fuel tables reach a rich calibrated limit. Refer to Section 1 , Powertrain Control Software, Fuel Trim for more information. Air Measurement System

• MAF sensor (contaminated, damaged, malfunctioning, etc.)

Fuel System

• Fuel pressure regulator (leaking, malfunctioning, etc.).
• Fuel filter plugged, dirty.
• Fuel pump (weak, check valve leaking, etc.).
• Leaking/contaminated fuel injectors.
• Low fuel pressure or running out of fuel.
• EVAP canister purge valve leaking (when canister is "clean").
• Fuel supply line restricted.
• Fuel rail pressure sensor (incorrect reading).

Air Induction System

• Air leaks after the MAF.
• Vacuum Leaks.
• PCV system (leak, valve stuck open, etc.)
• Improperly seated engine oil dipstick.

Exhaust System

• Exhaust leaks before or near the HO2Ss (exhaust manifold gasket, mating gaskets, etc.)..

EGR System

• EGR valve tube/gasket leak
• EVR solenoid vacuum leak

Secondary Air Injection

• Damaged/malfunctioning secondary air injection system (mechanically stuck valve).

View Freeze Frame Data to determine operating conditions when DTC was set. Observe LONGFT1 and 2 PID(s). Refer to Section 2 , Adaptive Fuel DTCs Diagnostic Techniques for more information.
P0457 - EVAP Control System Leak Detected (Fuel Filler Cap Loose/Off) A fuel tank pressure change less than a minus (-) 7 inches of H 2 0 in 30 seconds has occurred after refueling; or there is excessive purge (fuel vapor) flow greater than 0.06 pounds per minute.

• Fuel filler cap not installed on refueling (storing continuous memory DTC) and "Check Fuel Cap" light may also be illuminated.
• Fuel filler cap missing, loose or cross-threaded.

Check for missing fuel filler cap or integrity of the cap. If OK, clear continuous memory DTCs and re-initiate EVAP Emission Running Loss Monitor Drive Cycle.
Stuck open evap purge valve , maybe. Take your vehicle to a qualified repair shop an have the evap system smoke tested .

P1151 - Lack of HO2S-21 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130

check fuel and air flow and may be a fuel sensor or an idleing sensor

take sample of your fuel into clear plastic bottle from fuel line
is there any water present?
this can cause these codes and then not go on storing codes for other bank even though that bank will be missfiring also due to water & P0300 Random/Multiple Cylinder Misfire Detected being logged
check all connections to coils/leads & wiring connectors
due to miss fire codes for cyl 1,3,5 all on the same bank
also look and check for air leaks on that bank (hose knocked off or splithose)inlet manifold gasket,brake booster etc...
3 injectors being blocked slightly on same bank posible!!!
check wires and signal

was it running like this b4 tune up & repairs?
this is what codes are
P0170 Fuel Trim Malfunction (Bank 1)
P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0305 Cylinder 5 Misfire Detected

the last code is for trans due to misfire/running lean on bank 1 probably a torque problem code

I'ts normal on old trucks. But without further analysis i can only refer these problems.1 Your air fuel mixture is either lean or too rich. usually and o2 or Oxygen sensory problem.it causes a starved engine failure or what you described.
2. you have a possible vacuum leak
3. your egr valve has broken seal or gap
4. you dont have constant power like (spark, fuel or alternator/battery)
been doing mechanics for 10 years. So safe to say im close or on the dot!
