SOURCE: How do I remove the intake manifold on my 03

That is all the basic stuff unless you feel you need to change injectors or knock sensor which probably isn't necessary. The intake has about 8 bolts that you can remove after all vacuum lines are disconected. If you would like further detail and illustrations, I suggest go to autozone.com and register for free, then you can view a full free online repair manual

SOURCE: I have a 1997 Mitsubishi Galant with rough idle

I am having the same issue on Mitsubishi Galant 02. Clattering on acceleration, herky jerky idle. Pulled a code multiple cylinder misfire. My mechanic's diagnosis is bad valve cover gasket causing oil to seap into the spark plugs and bad timing belt, which I have not replaced at 150k miles. I do however know my fuel injectors do need cleaning, he hasn't ruled that out either. Have you pulled any code on it? I have read on engine knock sensor going out on some of these also. Hope this helps some.

Where is the pvc val located on 2001 Mitsubishi Galant


The pcv valve will be on the valve cover. It will have a tube coming to it. You can pull it out to remove it. Shake the pcv valve, if it doesn't rattle, it needs to be replaced.

Ps300 code


I think that you have a typo and believe that you meant p0300.
If so p0300 means multiple cylinder misfire.

A tune up will usually fix this problem.
spark plugs
wires
ignition rotor ( if it has one )
distributor cap ( if it has one )
Ignition coil
pcv valve.

Check your tune up.

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.


I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

How to tune up 96 chevy corsica


You will need a 3/8" drive ratchet with a 5/8" spark plug socket. There is no distributor on these engines so you won't require a dist. cap. You will want to change spark plugs, ignition wires, air filter, fuel filter and pcv valve. There are no other adjustments.

I have a 1999 Mitsubishi Galant and need to know how to put on a valve cover gasket. Oil is leaking out and dripping and it's causing it to burn and smoke comes out of the car.


Instructions
    • 1 Allow the car to cool. Disconnect the battery terminal. Remove the right side vent screen top extension. Disconnect the ignition coil with power transistor and its wiring and brackets.
    • 2 Disconnect the left hand side coil wires and spark plug wires. Remove the spark plug wires, valve cover bolts and the valve cover. Unplug the electrical connections from the intake manifold runner control actuator. Unfasten the actuator retaining the screws, right bank heated oxygen sensor front and rear.
    • 3 Remove the heated positive crankcase ventilation (PCV) valve. Remove the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor. Disconnect the ignition coil with power transistor and its wiring and bracket. Remove the valve cover bolts, the valve cover and the old valve cover gasket. Clean the valve cover seating area with automotive engine cleaner and place the new gasket in the gasket seating area.
    • 4 Replace the parts that were removed and disconnected by reversing the steps. Replace the valve cover gasket and tighten the bolts, in sequence, ensuring not to over tighten. Put back the ignition coil with power transistor and its wiring and bracket, the heated positive crankcase ventilation (PCV) valve, the heated oxygen sensor plug and the Differential Pressure Feedback EGR (DPFE) sensor.
    • 5 Add oil to the car. Start the car and let it run at idle for a while to check for leaks..

Missing, think it needs an tune up. where is the fuel filter located? do i have to take it to a repair shop for the tune up? i am good with the older cars but this one is alot different


NO YOU DON'T! THE TUNE UP IS JUST AS EASY AS THE OLDER CARS, BUT YOU DON'T NEED TO SET THE POINTS, OR REPLACE THE CONDENSOR! JUST THE PLUGS, WIRES, DIST. CAP, AND ROTOR CAP! NEW AIR FILTER, PCV VALVE IF IT NEEDS IT! SOME OF THE FUEL FILTERS ARE LOCATED ON THE FRAME RAIL, ON THE DRIVER'S SIDE (LOOK THERE FIRST! IT WILL BE TOWARD THE DRIVESHAFT SIDE OF THE FRAME!
