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!

Hello;
It sounds as if you have a couple of possible problems. First could be the fuel pump. If yoou disconnect the fuel line, put the line in a jar and crank the engine over, you should get a pint in 15 seconds or so. Also check the pressure, should have around 5 psi. Secondly, you may have a vacuum hose cracked, broken, or leaking. Check your hoses and also the carbureator for leaks.
Hope this helps;
Thanks;

Could be a throttle position sensor going bad or a loose or leaking vacumm line or loose or worn wiring harness. You had mentioned the engine starts heating up. Do you mean overheating or operating above normal temperature? Sounds like a vacumm issue with the fluctuating idle. Check for worn vacumm lines and check to see if the vacumm is functioning. Sometimes a simple vacumm line with a loose connection or a small hole in it can affect your idle. Old lines are easily replaceable and an inexpensive place to start, then try your egr valve, pcv valve, brake booster vacumm line, oxygen sensor could be worn and affecting the mapping of fuel and air on the computer. Usually the check engine light will come on in this case.

22r rough idle


Fuel injected or carburetor? If it has a carb check the idle circuit! Also look down the top of carb with air filter off and make sure fuel is not dripping down the inside venturies. Take some carb cleaner an check for a lean mixture at idle and also use the carb cleaner to check for vacuum leaks around base of carb.

It shouldn't run at all with the solenoid disconnected. That should be 'ON' when the engine is on, or it won't run. Maybe the solenoid circuit is dirty so that it only opens a bit, or the fuel it allows through is limited by a dirty passage. I wonder why the wires were disconnected in the first place. It shouldn't run if that is the case!
