i just cleaned my throttle body and maf cleaner 3 days ago and i ve noticed that my rpm never dropped below 500 anymore. My rpm used to randomly drop below 500 rpm when driven like under 40 mph under braking.

I only clean my throttle body with the spray and didnt used any brush to throughtly clean it, so i think cleaning my maf element helped my idling.

Any one else notice their idle after cleaning their maf sensor?

 

Makes sense, a lot of people experience a little bit of a higher idle when they clean the throttle body.

 

Mine did the same thing, I always thought it was weird that the car would drop that low in idle when im going 35MPH and let off the gas, but I only cleaned my throttle body.

 

did you guys notice it when your coming to a stop and the rpms dip under 500rpm then come back up to normal idle?

 

Yep, mine will still do it every once in a while, but nowhere near as much as it did

 

Interesting!! I might actually do this procedure this week. My car idles at about 600rpms. I am a 5spd though and its only happens when the car is warm.

 

yeah after i replaced my plugs i noticed it stopped doing it for awhile, now i notice it does it when clutch is in and coming to a stop or if i rev it up it dips just below the 500rpm mark then goes back up to around 650-700. Maybe ill give this a try on tuesday.

 

I have a 97 auto. it idles low around 500, and stall occasionally. It may be caused by a dirty throttle body? I'll have it clean right away. When my car stalled, it won't startup right away though, I have to wait for 10 minutes before I can start it. Maybe it's more than just a TB clean? No codes shown.
Any suggestion?

 

Probably more than a dirty tb but clean first and see what happens. Also, you guys might think you're idling at 500 but you're not. I thought the same thing a while back until I have a summit rpm switch. It shows digitally what rpm I'm at and it was higher than I thought. Almost looking like 500 rpms and about 650 for me. And that's actually not bad for idle. You're idling should be about 650 if I remember correctly.

 

What do you guys say would be the best thing to clean tb?

 

Obviously, throttle body cleaner.

Go to an automotive parts store and tell them what you intend to do.
