Some help for you, not exactly super with yugo's but they do use internal combustion engines like other cars,so start by pulling the plugs one at a time and doing compression check on cylinders, changing the plugs when you are done, the go on to fuel injection and a good cleaning would help, then drain and change the oil using the proper oil to refill with. cars now a days are very touchy to the oil viscosity you use in them. there is an idle air control motor on these engine that control air flow to the fuel mixture make sure to clean it also. you might check the wires going to the idle air control motor. make sure you show a reference signal of about 1.5-3volts in the power wire. you will normally hear it a little opening up. hopefully some of this helps. if compression is considerably low in anyone of the holes then spray a little wd-40 into it and re-check if pressure goes up alot then time to do more investigation. good luck, let me know what you come up with and ill help you more if you need.

My 2004 mondeo 1.8 16 v is playin up firstly when you start it up revs are on 1500 revs but then calms down to just under 1000 revs and when youd accelarate car just wants to slow down and also steering...


starting on very cold mornings ,the engine will run at high rpms (just like you have a choke on) and then will after a minute or two return to idle rpms( most cars is around 850-900)
If you have a hydraulic clutch and you have never changed the fluid then I suggest that you have it done as the fluid is probably freezing the water content in it ( brake fluid is hygroscopic-- attracts moisture from the air)
Check the linkage adjustments for dirt and other foreign objects stopping full movement or if the lever is direct into the top of the box then check the gear lever pivot at the top of the box for loose or adjustment.
If you have a cable clutch ,consider replacing the cable.

Revs high when i change gear


Is it possible the clutch pedal is interfering with the throttle? Start the engine in neutral and allow it to idle. Press only the clutch pedal down and see if this increase the engine speed. If it does speed up the engine and slows back down when you release the clutch then somehow this operation is where your fault lies. If it doesn't alter the idle speed, then rev your engine and release the throttle to see if it returns to idle immediately. If it is slow to return to idle then your throttle cable could be sticking. This means when you change gear lifting off the throttle has little effect and depressing the clutch to change gear causes the engine to race as the throttle is still partially open.

Is it normal for the revs to stay up when changing gear in a 2002 4x4 3.0L turbo diesel navara?


do they revs drop off when taking pressure off accelerator pedal when out of gear? if only staying high during gear change it would suggest a worn clutch friction/pressure plate so the engine isn't slowing down when clutch is depressed .I'd also have the OBD codes read to see if there is a sensor/switch at fault , but sounds like the clutch to me

Engine revs but no acceleration


Clutch plate and pressure plate seem to be too weak to pull the car. Or one of the CV joints is detached from the gear box. To test the clutch plate, park the car on flat surface. Pull the hand brake up, start the car, depress the foot brake pedal, depress the clutch pedal, put the car in 1st gear, press the gas pedal and leave the clutch pedal at once, while keeping the brake pedal depressed.
Follow one of the two following statements:
1. Engine does not shut down and remain start. (Clutch plate, pressure plate and clutch bearing defective - Replace all as a set)
2. Engine shuts down. (Clutch system is OK and does not require any repair).

Manuel transmission wont go into gear.


First, is your clutch working? Check this by turning the engine off then put the car in first gear. Firmly apply the parking brake and fully depress the clutch pedal and hold it depressed as you crank the engine. If the engine starts and the car and revs normally then check the oil level in the trans. If the car tries to jump forward then adjust the clutch.

How do can you roll start a 86 samurai


Engage two wheel drive. Switch on the ignition. Pull out the choke? Engage second gear and release the hand brake. Depress the clutch pedal and get the vehicle up to about 6-8 mph. Release the clutch and the engine should be turned by the rotation of the wheels - and hopefully start. Once the engine has caught, depress the clutch and keep the engine running in the normal manner.

My 2004 audi s4 makes gronchy noise when i put it in to 2nd gear when cold whats causing it?


If I've understood your problem correctly.....when changing from 1st gear into second the box is giving a metal on metal crunching sound?
  • This would be the syncromesh ring which is not equalizing the speed correctly.
  • The problem usually happens when there is wear on the same part.
  • Check to make sure that the correct transmission fluid has been used in the box.
  • To alleviate the problem and delay the time when it will require attention, use the double de- clutch method of changing gears, especially when the transmission is cold.
  • The double de-clutch is carried out in the following way.
  1. When in gear and changing from 1st gear to 2nd, change into neutral and release the clutch and then depress again before selecting 2nd gear....It is not required to rev the engine in the neutral position when changing up....
  2. When changing down rev the engine when the shift lever is in neutral for each change.
You'll soon get the hang of it and stop the crunching sound, protecting the box at the same time....

Engine sputters when clutch/brake engaged; revs when brake only engaged


check under dash where pedals are as there may be wiring there that the pedals are touching and shorting out
