I need to know which feeler gauges I need when adjusting valves on 1998 1.5 mitsubishi mirage engine

The most common setting for those engines is 0.14mm for Both valves.

First of all you will need a decent set of tools. depth feeler gauges, a workshop manual with the valve clearances, and a method of turning the engine by hand. You will need to take off the valve covers. After this you can check each of the valves for clearance by sliding the feeler gauges into the gap between rocker-arm or cam lobe and valve or tappet. Trick is you can only do this when the engine is in the correct position, so consult the manual and rotate the engine by hand accordingly. Remove the spark plugs to make rotating the engine easier. Adjust the tappet to gain the proper clearance as documented in the workshop manual. The feeler gauge should drag just slightly as you slide it out or slide it in. In ideal conditions I would guess this is about a 2~3 hour job, assuming ideal conditions, and not too much stuff in your way that will need to be moved. If your working at home, those are not ideal conditions.

For the record I've only done this sort of job on motorcycles, so I've never actually adjusted tappets. The theory is the same though.

No you don't have to, but if it has to be removed to replace the pump, why not be safe then sorry and replace it. They are not expensive and if you break a belt, you could possible get internal engine damage if the motor has interference valves in the engine

Valve cover gasket may need to be replace.
Please don't forget to rate me.

There is an adjustment to be made. Loosen the bolts and adjust the rotation until the specs are met.

MANUAL TRANSAXLE

1. Detach the connector from the throttle position sensor.
2. Connect an ohmmeter between terminals IDL and E.
3. Insert a 0.004 in. (0.1mm) feeler gauge between the throttle stop screw and stop lever.
4. Verify there is continuity between terminals IDL and E.
5. Then replace the feeler gauge with a 0.027 in. (0.7mm) feeler gauge, verify there is no continuity between terminals IDL and E
6. Then open the throttle wide and verify there is no continuity again between terminals IDL and E.
7. Next, connect the ohmmeter between terminals POW and E.
8. Insert a 0.004 in. (0.1mm) feeler gauge between the throttle stop screw and stop lever.
9. Verify there is no continuity between terminals POW and E.
10. Then replace the feeler gauge with 0.027 in (0.7mm), verify there is no continuity between terminals POW and E.
11. Then open the throttle wide and verify there is continuity between terminals POW and E.
12. If not as specified, adjust or replace the throttle

AUTOMATIC TRANSAXLE

1. Detach the connector from the throttle position sensor.
2. Connect an ohmmeter between the terminals IDL and E.
3. Insert a 0.004 in. (0.1mm) feeler gauge between the throttle stop screw and stop lever.
4. Verify there is continuity between terminals IDL and E.
5. Insert a 0.024 in. (0.6mm) feeler gauge between the throttle stop screw and stop lever.
6. Verify there is no continuity between terminals IDL and E.
7. Connect an ohmmeter to the throttle sensor terminals Vt and E.
8. Verify that resistance increases as throttle valve opening increase.
9. With throttle valve fully closed the resistance should be below 1 kilohm and as throttle valve is fully opened resistance should increase to approximately 5 kohms.
10. If not as specified, adjust or replace the throttle sensor.

there is no idle screw, idle is controlled by the ecm via the ias(idle air control)

It could be that the valves need adjusting or redone. When they heat up it swells the rubber and the metal. If you have a bent valve it should do it all the time or it could be one of the valve springs is going. Either way it sounds like it is something in the valve or the valve seats or the springs.

When setting tappets, it has to be born inind that the valve stem wears an indentation into the face of the rocker. This prevents a really accurate tappet adjustment, so the customer is right again. If you do not posess a tappet setting dial gauge, a normal engineers dial gauge will do just as well. The procedure is the same as using your feeler gauge except that you set the dial gauge up on the cylinder head with the pointer resting on the head of the rocker. Press down fairly firmly on the rocker valve end and zero the gauge. Next lift up on the rocker and read off the clearance, from the gauge, Use a magnetic base to support your gauge and repeat the pocedure for each valve pair.

Valves Yeah. Put Some Valve Cleaner In Your Gas You Can Buy It At Pretty Much Any Auto Parts Store For About $5.00 If This Doesnt Fix It You May Need A Valve Adjustment.

A Valve Adjustment If Done Yourself Will Take A Repair Manual, Feeler Gauges And A Wrench.
