2006 Mits Endeavor missing and sputtering. When I fill up, gas will leak below the car. Fuel leak in stem of the gas tank? Gas tank leak, fuel pump, spark plugs? $300 to pull intake to check plugs


This sounds like a Evaporative systems issue. There are valves in the fuel system to keep it pressurized and if you have a broken/rusted-out fuel fill neck that can NOT happen.

I'm guessing you have CEL/MIL (Check Engine Light) on that needs to be checked (regardless of if you think you know what it is - check it again). Most Auto Parts stores will connect a scanner and read the codes for FREE. Get this done to get the Code.

My 93 nissan sentra service two door five speed had rust and water in the fuel I replaced the pump filter and cleaned the tank why dose two of the cylinders not miss like there not firing


Pull out the spark plugs to see their condition, if they look fine check the resistance on the wires and make sure the distributor(if it has one) is fine too. Another thing too it can be a fuel injector that went bad

92 toyota pu surges in high gear


High gear strains the engine more than others, so any tune up item could cause this. Leaking vacuum line, bad air flow sensor, clogged converter or muffler, weak fuel pump or dirty fuel filter all can cause this. I have also seen rust in fuel tank go right through filters and make metallic deposits on spark plugs which will then miss at high speed first and soon at all speeds. Try pulling plugs and "reading" them first. Then test fuel pressure while running at high RPMS.

My front three spark plugs are dry and rusted. car was runing rough so I pulled plugs to find out they are rusted. After cleaning them up and puttng back in my car it runs worse and now the check engi


How Many Miles are on it ? I would suggest changing all 6 with new ones and also plug wires, should take care of your problem, you might of crossed the plug wires when you pulled them off. starting from passenger side should be 123 and wires have #'s on them, a trick to get to rear plugs pull alternator off and you can get through to back plugs a lot easier

Freeze Plug. How difficult to replace?


It depends which one will need to be replaced. Plugs just dont go bad, if its rusted out, its because just water or weak antifreeze has been in the engine and they will all need to be replaced, sooner or later. You need to flush the cooling system, replace any hoses that feel crunchy or soft and I would recommend brass plugs if you can get them. The water pump may have damage from the vanes rusting. and the radiator blocked up with rust. When you get the old plug out, you can guess the condition of the others by the back of the plug.

Rusty anti freeze came pouring under my 2005 dodge caravan


I hope you're not driving it...They're called freeze plugs, and they are for when you have added too much water (not enough anti-freeze) to the system and it gets too cold, the freeze plug should pop out before the block cracks (very expensive). The extra water content also helps the plug to rust. They're relatively cheap, and not too hard to replace (if you can get to it without pulling the engine). I'm not sure about the Dodge, but most plugs are a press fit, meaning you simply put the plug up to the hole (make sure the old plug is out), take a small block of wood to evenly distribute the force to push the new plug in, and tap it in with a hammer until it is flush with the block. And make sure to fill your radiator with a 50/50 solution of water and anti-freeze...
