Sounds like a charging problem. When your battery runs low there is not enough current to operate the sensors properly. When you charged the battery it thought the system was fine till it gets low again. I would have your alternator checked and battery. Good luck and have a great day.

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.

Running rough


If your car is running rough and it's fuel injected (which yours is). Follow the air intake (black plastic box - housing the air filter that has tubing that goes to the motor) until it reaches the Throttle body (rounded metal air intake at the end of the plastic tube - has one large flap inside). You will want to remove the hose clamp and thoroughly clean the throttle body and the AIC (air idle control valve - small canister attached to the throttle body). Use off-the-shelf cleaner from any automotive store. This takes about 30mins to 1hr depending on your skill level. This will result in a cleaner smother idle and smoother performance. This is a common issue in today's cars. I have to do this once a yr to keep my modified car running happy.

Take a look at the later parts of this article for pictures to give you an idea:

Rough idle, backfire on acceleration


check everything you can under the hood your air intake system all of it especially make sure all clamps are tight .. and make sure all vacuum hoses are good and not cracking or broken or just loose . you might run a little fuel cleaner through a tank of gas too cleaning the engine fuel system up some. just a few ideas..

Rough idle


a cheap and easy thing to try is to clean the carbs. get some carb cleaner and run through your next tank of gas. Also a batch of bad gas can cause the problem too.
