Well I decided to clean my Maf sensor and Throttle body because , I thought that would stop my car from dying whenever I push my clutch in coming to a stop. I could start the car it would idle like around 16-17. Then once its warm it would settle for a minute then the idle would drop. I would blip the throttle to try to keep it alive but it just gets stuck at 2,000 rpm. So I would turn the car off. Tried to crank it again the revs go up like it wants to start but the car just dies. The car is not throwing any codes. Already replaced the maf. Dont know what it is possibly fpr, iacv, o2, or map sensor?

 

What did you clean the throttle body with?

 

Crc maf cleaner

 

Everything plugged in?

 

As far as I know. I'm going to double check when I get free time.

 

Did you wipe the TB out with a rag? If you did, you removed the coating that seals the throttle plate to the bore of the TB. You'll have to redo the coating..

 

Yea, I wiped the tb out with a rag. I cleaned the tb while it was still on the car. Thought the seal was on the inside of the tb?

 

Inside of throttle body is coated from the factory.

So... You should change the title of your thread to "Should of never cleaned the throttle body." j/k

It is a common mistake, don't feel too bad. It is a good time to maybe order a spare stock one and redo the TB shaft seals and then swap on a good "refurbished" unit that is good to go for higher boost and a few years of service.

 

I'll check today when I get home to see if there is a gap. I actually do have an extra tb but I think it's from an 8. Wonder if they are interchangeable with the 9s.

 

Pretty sure they are... I used one from a friends 9 when I messed up installing the TB seals and damaged one.

 

Checking the throttle body next week mostly likely going to reseal the throttle plate. I wanted to try something out so I unplugged the maf sensor and the car started up and idled normally. Wondering if that wire thats showing might be causing it.

 

Try resetting the ECU by disconnecting the negative battery cable.

 

There's an abraided compound used for the sealing. You don't need to get a new one in order to fix it.

 

Tried resetting ecu it didn't help. Going to buy some lps force 842 dry moly lubricant to see if fixes it.

 

Update: Ok well I sealed the throttle plate. Put everything back together. When I start the car back up the afr is reading 17 and sometimes shows ---. After the car warms up it reads the afr reads 14-15. Then the idle starts going back up and stays at 1.5k rpm. Can't remember the afr reading so I decided to turn the car off.
