Hi and welcome to FixYa!

Two things can cause this problem. I do suspect that you have fuel flooding. When you're uphill you tend to press the accelerator and while you floor it there's a lot of fuel coming in but can't be burned enough. The solution is to replace the spark plugs for it can be worn. Once the plugs are replaced you'll have a better fuel burning.

The other common cause is a faulty torque converter. The torque converter controls the shifting of the car. If the torque converter fails to shift you tend to press the accelerator and you'll surely have fuel flooding. Have the torque converter replaced too and you'll be good.

Hope this helps and thank you for using FixYa!

Technically it is a sealed unit that has an EVAP purge system to control Hydrocarbon emissions.
Does it always have air rushing in every time you take off the cap? Is there a check engine light on and are there any trouble codes stored in the computers memory indicating a fault?

WHAT CAUSE A MERCURY VILLAGER TO BOG GOING UP A HILL


when the tank gets low on fuel(under 1/4) or less.. the pump, which uses the gas to keep cool, will get hot and start to cavitate(run at slower speeds and cause a severe fuel pressure surge)..the engine will respond accordingly..most will do this as the system gets older..to avoid it and possible premature pump failure, keep the tank at least 1/4 fll..

Push down on gas pedal bogging then goes


It could possibly be that there is a wore spot on your throttle position sensor (TPS). It basically is connected to the cable running to the gas pedal and tells the computer how much you're pushing down on the pedal.

If you find that it's bogging down more and more often (like when you need more power climbing hills and never really gets going), it could be that your catalytic converter is clogged, but this will eventually throw some check engine lights.

Im suspecting a problem in the fuel pickup tube in the tank. Possible rusted and when you have the fuel run to the back of the tank the hole is exposed allowing the pump to pump air and you are in effect running out of fuel pressure.. Suggest you consider pulling the pickup unit and check .

This could be a TPC valve or sensor. That is a throtel position control. Your engine will idle or run at low speed fine or in stop and go traffic but highway driving or climbing a hill when the demand changes to heavy or light consumption it will surge the engine as it can't get a good read on what it is suppose to do. This is a resonable priced part and for about twenty bucks for a CHILTON manuel for your car it will give you step by step instructions on this and almost any project you want to try yourself. They will have these at your autoparts store.

When I try to accelerate my car has no power!


There could be a couple of reasons. Yes a tune up would be nice. But my not fix the problem. If you are not losing acceleration on straight away but on hill, then it could be the torqe converter. Also have your MASS airflow sensor checked and air filter.

Also check your fuel pressure at the fuel rail. Get a fuel gauge and look for a port on the fuel rail for a port that looks like the valve on the tire. Screw it in and crank the car. You will have to call the part store to find out what pressure it is supposed to be. If there is low or eratic pressure the its the filter or pump

Engine looses power going up hill, no check engine light at this time.


How old is the Catalytic Converter, sometimes they will get clogged up and affect performance.
Good luck
