SOURCE: Rough idle until warm 22r
if it is a carburated engine it is probably the a.a.p. diaphragm in the carb. if you remove the air cleaner and look on the side of the carb that is towards the valve cover near the front yow will see a vacuum hose going to a cover that is fastened with 3 screws. if you pull the vacuum line off you will see that there is probably fuel being sucked into the line due to the leaking diaphragm. the vacuum source is temp controlled and cuts off when warm. but when cold sucks fuel directly into the intake. remove the 3 screws to replace the diaphragm, being carefull of the spring. good luck!

You have to take apart the 4x4 hub to get to the lock nut for the bearings then you have to reome the hub and rotor assy,then you have to press the wheel studs out to remove the rotor,then reverse the process.

There is an adjustment for the clutch pedal under the dash where the push rod goes thru the firewall. There is only aprx. 1/2" of adjustment so be careful when making an adjustment, if your clutch is slipping then you need to shorten the throw of the push rod.

HI, i would advise to check the following areas for faults. replace any part that is fouled or malfunctioning.
1. Check the air filter- This device may be clogged or dirty. replace if visibly fouled.
2. Check the fuel pressure regulator- pull the vacuum hose of the regulator. if there is gas in it, replace the fuel pressure regulator.(if there is no fuel present in the lines, move on to the next check point)
3. Replace the fuel filter and, check the voltage at th fuel pump. you should get 12V at the pump. if its lower than twelve, chekc the ground for corrosion as well as the entire wiring harness as well. all the way to the relay for fualts.
4. Check the Intake Manifold Gasket for worn or damged edges. this ware and tare will cuase leakge. replace this gasket if found to be fouled in any way.
5. Check the freash air intake hose. this hose may be clogged or damaged.
6. Last but not least, check the injectors for leaking seals and, correct pulse as well. replace any injector with a weak pulse or , leaky seal.
