Thread: 3800 V6 hot start issue

If you really wanna get it good, take apart the whole intake ducting, take off the MAF, spray it out with MAF cleaner (nothing else, anything else will destroy the MAF), then while the MAF is drying (air dry only, dont touch any part of the insides with anything), take the 4 bolts off the TB and yank the whole thing off the car, disconnected and all, douse it real good with TB cleaner, wipe it down with a rag, open it up by hand and wipe it all down good... and then while that is drying, get a rag wet with some TB cleaner and wipe down the inside of your manifold where the TB connects, as far in as you can get.

jmoore4294 linked you to a really good write-up earlier in the thread for all this.. maybe it's just me but I'd feel like I missed a lot of gunk if it was bad enough to cause issues, and then I only sprayed it down with it still on the car, and I dunno if you cleaned the MAF or not.

Hey thanks. I checked out that write up jmoore4294 put in the thread and it sure looks helpful.

I should get some MAF cleaner and clean it more throughly again. I should do the same to my Silverado as well. No, I did not clean the MAF and because it is so fragile is the reason why. I will clean it as well.

Our Grand Prix has been driving fine, but I'll clean it again now that the weather is getting better and I will make the time to clean it more throughly. Plus, the write-up from jmoore4294 will be better than using a shop manual as guidance to handle the chore.

I appreciate all of the useful input from everybody on this thread. It's good to know that these newer cars can still be maintained from the owner's own garage.
