What's the best way to clean the throttle bore? Do I spray it with carb cleaner while running as you do with a carb? Thanks.

I'm working on the rough idle when warm issue and am starting with this cleaning. Next, I'll get some of that BG Products 44K.

Personally if it was me, and I had the time, I would take it off, remove the sensors, spray it down and give it a good wipe, get into all the nooks and crannies and if possible soak it in alcohol for like an hour or so.

If I'm pressed for time, I would just run it at idle and spray seafoam into the TB.

 

The HO throttle bodies are easier to clean if removed as the IAC is a bear to get off with it installed.

The rEnix you xcan go either way. Always use a new gasket.

 

Thanks. I'll take it off. I like the idea of the alcohol soak too.

These basics have improved the rough idle when warm issue. I found four grounds and cleaned them all. I disconnected and lubricated (CRC 2-26) every electrical connection under the hood. I removed the throttle body and cleaned it. Also soaked it in alcohol as suggested. Cleaned up the IAC valve too as it had a lot of soot on it. Anyhow, not much money with good results. Thanks.

What kind of alcohol do you soak it in? Regular rubbing alcohol? I am thinking I need to take mine off and clean very well and wan to make sure I clean with right chemicals

 

Carb cleaner, brake cleaner, lacquer thinner, Jose Cuervo. Whatever gets it clean, and they all will get it clean.

 

Good job!! How much did you spend?

 

Thanks

 

The very best carb cleaner I have found is the Carquest brand.

takes off the brown film quick.

Brake cleaner spray cans work good also, dry quick....

 

After cleaning it with carb cleaner I soaked it in denatured alcohol. I usually keep a gallon of it around. You can get it at Ace or any hardware store. Good luck.

TPS soaked, too?

 

I was thinking denatured. I work at Lowes and was hoping that I would be able to get the recommended chemical from work (which I can) for my discount and convenience. Thanks for the tip
