Question about 1990 Mitsubishi Galant

Open Question

1990 galant 4g37 engine carbed. Runs to fast on cold start, how do you adjust to slow it down, and when the engine is warm it will not tick over at less than 1200 rpm, no amount of adjustment on the slow running screw makes any difference.

SOURCE: fuel consumption of my mistubishi galant ss 1990

Make sure the air filter is clean,make sure the oxygen sensor is ok but would have to suspect its carboned up due to vehicle age ,if not working properly it tells the engine to run richer than normal.Also make sure the plugs and spark plug leads are in good condition.It wouldnt hurt to put a bottle of injector cleaner in the fuel tank next service as dirty injectors will also add to fuel use.A few small things to do or check but worth it by the sound it.

SOURCE: Headlight adjustment

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

I've a 1981 Vette that idles very rough with a cold engine start.


You need to have the choke adjusted so it runs on a fast idle so the engine can warm up or you may need the carb to be rebuild and adjusted properly.

What kind of carb does the 76 c10 4x4 come with need to adjust


mcdevito75 here, The fast idle is needed when the engine is cold to make the air and fuel mixture rich to keep the engine running while cold, the carb. choke doew this with a bi-metalic spring in that balck round box on the side of the carb, a screw also hepls keep the choke closed until warm up, this screw can be adjusted tpo control how tight it holds the choke cloesed, here"s how to adjust this screw to slow fast idle speed, Locate on the carb, where the gas pedal connects, have a friend operate the gas pedal with the engine off, once you locate the linkage, you"ll also see 2 screws with springs around them, 1 is for fast idle the other for regular idle, you want the fast idle screw, notice this screw will lay against and Half moon shaped tab, while the other screw lays against a shaft, you need the screw that lays against the half moon shaped tab. Start the engine and step on the gas pedal slightly and relaease, at the screw that lays against this half moon, simply turn it counter clockwise or toward you just 1 2 or 3 turns very slowly, you'll hear the fast idle come down but you don"t want the fast idle to low, listen to the engine very carefully, slow it down just a bit, it should still race though but not out of control. Of course for a full carb, adjustment the shop should handle that., but this info will help.

1984 passat cl. the automatic choke runs too fast


the choke has 3 screws to adjust the unit,the choke itself will normaly be siezed inside at the age.With a warm engine, loosen the 3 screws and turn the choke untill the idle drops.

or as i did it-with a cold engine, remove the airffilter and with the 3 screws loose on the choke press the accelerator pedal just over half so the choke is engaged and the looking inside the filter housing adjust the choke flap by turning the choke housing until the flap is 3/4 closed and tighten slightly and start the car.Do remember to check your distributor timing whith a warm engine and make sure the sparkplugs and airfilter are okay as each upsets the other.

Problems accelerating


the engine tickover is too slow when the engine is cold its running on cold start, ie:choke,, after it warms up the engine slows down this is what is causing it to stall in gear,, get some one to hold the brakes hard on and with the engine running in gear ajust the tick over till its reving at 750 - 850 rpm the revs will go up a bit when its out of gear,, before you pick a gear to go into push the foot brake down to stop the car lurching,,,

1984 toyota corolla 1.6 engine. How do i adjust


Carbureted models have a fast idle cam on the throttle,It is a screw that sets against a movable part,called the cam,when the engine heats up,the cam will drop upon tapping the gas pedal.Set the carb,while the engine is cold,by tapping the gas pedal,then adjust the fast idle cam screw by turning it in,with the engine running.Start out by turning the screw in a full turn before starting engine so it will run,then adjust the screw as the engine runs.

Vitara JX 1.6 soft-top. Made in Spain 1998. Engine runs at 2000rpm when cold and only returns to idle after 10 mins or 6 miles in warm conditions. Can i adjust anything ? ps. I live in England


maybe slow,cold start,air control valve or,possibly normal for temp in morning,I live in Australia and cars can take ages to slow down in winter eg1 to 3 deg cel...and very quickly warm up in summer..eg....idle slows down in 1/4 time,have a look at the car if you can park it in warmer conds... to see if its quicker as Toyotas do this normally for fast warm up,lastly has it been well serviced...looked after??
