Sometimes (more often then not) If I blip the throttle - the idle dips to ~500 the goes to back to normal.

Do I have an issue? (The Car - of course I have plenty)

 

Mine does the same thing. I thought it was a vacuum leak, but none were found.

 

I would think that that is normal... my z06 and a g37s I had both did/do that

 

Mine also does that...It did it alot more until I changed the original MAF sensor at 25,000 miles...Now it still does it occasionally....

 

I don't know that this is normal...perhaps you may like to have it checked & report back your findings...

 

It tends to be common with e-gas but more apparent on cars with more than "low" miles. Have your T-body cleaned. You will find lots of gunk. after that could be the maf. Try the cleaning.

 

Thanks - I'll clean the T-Body and MAF. The t-body doesn't look to hard.

 

I also get it. If it would be T-body or MAF it would surely do it all the time. I only get it occasionally. Really annoying as it usually happens when I am not ready for it and I stall the car in front of traffic lights!

 

I had a bad MAF and it did that all the time. Replaced at the dealer and now it just does it like everyone elses after throttle blip, but balances back quickly.
The A/C compressor is also very noticeable while working on our cars (in regards to RPM)...

 

Cleaning the MAF helped a lot. I didn't have the time to take off the intake manifold to clean the TB - I'll tackle it at some point.

 

Mine does the same but only when the A/C compressor is engaged.

 

How did you clean it?
