Trying to put a new vapor canister in 95 grand Marquis.I got two lines running from engine to plug into canister but my connection has two plugs for my lines but on canister still a open hole nothing to plug into it. How do I do this

Sounds like the purge solenoid fuel it backing up in the canister with a failed vent solenoid replace bolth

this should help you
How to Replace Vapor Canister 1992 Grand Marquis

Check the following conditions:

• Absent or tampered fuel cap.
• Absent or tampered O-rings at fuel vapor and EVAP purge line canister fittings.
• Cracked or punctured EVAP canister.
• Damaged source vacuum line, EVAP purge line, EVAP vent hose or fuel tank vapor line.
• Poor connection at the ECM. Inspect the harness connectors for the following conditions.
• Backed-out terminals.
• Improper mating.
• Broken locks.
• Improperly formed.
• Damaged terminals.
• Poor terminal-to-wire connection.
• Damaged harness. Examine a) the wiring harness to the EVAP vent solenoid, b) EVAP canister purge valve and c) the fuel tank pressure sensor to ensure whether an intermittent open or short circuit prevails.
• Kinked, pinched or plugged vacuum source, EVAP purge, or fuel tank vapor line. Ensure that the lines are not restricted

PO 441 -is an EVAP System problem

You can not do EVAP at home too well

There are several things that can make it necessary to replace the charcoal canister. It could be saturated with moisture (water). This can cause all kinds of problems with your evaporative emissions system including low or no flow of the fuel vapors to the manifold with the engine running and "purging"and high hydrocarbons escaping into the atmosphere when the engine is shut off because water saturation will prevent the hydrocarbon absorption that the canister is supposed to provide. This type of failure can be verified by removing the canister and either turning it upside-down andsee if any water runs out or (preferred method) measuring the weight of the canister. A saturated canister will weigh much more than a new one. Most manufacturers provide specifications for this.

A very common problem with charcoal canisters is that the charcoal bags inside the canister burst and the little charcoal pellets are released into the vapor lines. This can cause everything from clogging the vapor lines to jamming the vent solenoid or the purge solenoid. The pellets can even get drawn into the intake manifold and cause damage to valves or pistons.

Another common problem with charcoal canisters is that they can develop large cracks in the housing. The cracks are usually the result of water saturation that has frozen during cold weather. When the temperature rises and the water inside the canister thaws, there is now a large vacuum leak that can cause everything from Evaporative Emissions fault codes to "lean oxygen sensor" codes. This can also cause extreme amounts of dirt and debris to be ingested by the engine - particularly on vehicles with the canister in the rear. Dust and dirt gets stirred-up by the front wheels and wind draft and the rear gets blasted with it. The large vacuum leaks that can be created by cracks in the canister are like a magnet to this stuff and of course, get ingested by the engine.

Can it cause your Check Engine light to come on? ABSOLUTELY! The problems listed above can cause all kinds of engine control problems that will cause the light to come on. The most common codes would be "EVAP Vent Solenoid", "EVAP Purge Solenoid", "FTP Sensor", and "O2 Sensor Lean" codes. (There is no fault code for the canister itself, but canister failure can be the ROOT CAUSE of several codes)

what codes?

The vacuum lines run from the canister to the intake manifold. One is the purge hose to deliver stored fuel vapor to the intake to be burnd when engine is warm and you are crusing at part throttle. The other line is the vacuum line to operate it.

Fuel Vapor Valve, Aerostar (4.0L Engine) The evaporative emission valve (9B593) uses a small orifice, 1.83mm (0.072 inch), that allows vapors to pass into the vapor line running forward to the evaporative emissions canister (EVAP canister) (9D653). This evaporative emission valve mounts directly into the fuel tank (9002) using a fuel vapor separator seal. Fuel vapors trapped in the sealed fuel tank are vented through the orificed evaporative emission valve. The vapors from the fuel tank leave the evaporative emission valve through a single vapor line and continue to the evaporative emissions canister in the engine compartment for storage.

Fuel Vapor Canister Purge Regulator Valve, Aerostar, Ranger Removal and Installation

1. Disconnect wire harness from evaporative emission canister purge valve (EVAP canister purge valve) (9C915).
   

1. Disconnect wire harness from thermistor.
   

1. Disconnect evaporative emission canister purge valve assembly from fuel vapor canister and throttle body.
   

1. To install, reverse removal procedure.

Well it could be a few things if you pull the plug out and there is oil sludge on it the engine is dirty. You can try and run some rislone in it for about 100 mile then change the oil short of an overhaul. Now if you pulled the plug out and it has water on it you may have a water jacket leaking. It could be a burnt valve most of the time if it is a burnt valve when you put the engine under a strain it will run worse.

It could. It's quite possible that the extra ports are not for the canister. Run the line for the vapor canister and plug the other 2 off with a cap. Use a small piece of vacuum line and put a screw or bolt in the end of it. Hope this helps.

check the charcoal vapor canister located under the hood,it reclaims the vapors and can plug up

if your obd2 scanner fits the connection you have obd2, obd1 connector is way differnt.
