when i started to get a rough idle in gear cold and warm, with accessories on or off. with 269,xxx miles on it, I cleaned the Mass Air Flow Sensor, and Throttle Body. Using a Mass Air Flow Cleaner from BG and just a Toothbrush and Carb and Choke Cleaner on my Throttle body. about 6k miles later it returned with a slight rough idle, and I replaced my PCV Valve for the first time, now it purrs like a kitten.
Total repair cost 6.99 for Mass Air Flow cleaner from BG
3.99 for Carb and Choke Cleaner
9.99 for PCV Valve.
I have 200,+ miles on the car. I change the plugs and wires yet it runs rough at idle and runs smooth at crusing speed. What can i do?
If an alternator is going bad it can cause a rough idle in a 1993 Subaru Legacy. Cold temperatures in the winter can also cause a rough idle in the Subaru Legacy.
throttle body or idle air control value
Almost all GM products idle rough when its cold but, if it continues it may be the tps swich.
The choke mechanism on your 98 Explorer could be sticking. The EGR valve could also not be functioning right. Either of these issues could cause the rough idle problem.
why does my vr commodore idle rough when at complete stop
Why does my 2001 kia sportage idle rough?
rough idle smell gas
40 to 50 psi while idle 22 psi after engine has been off for atleast 5 minuetes
Either timing belt and pulleys or distributor... had to replace both on mine and the coils were shorting out and so were the wires.
You dont , it is adjusted by the ecu and the "Idle speed control Valve" now the idle speed control valve might be stuck , so you can remove it and clean it up with some carb cleaner and wd40 , it is located underneath the throttle body
When the idle goes rough, you must idle the plugs. Else the car plugs roughly.
