I have a 99 gtp. I have new fuel filter, plugs and wires. Also new tps and air ideal valve. So my issue is when I start it up it seems like it's sputters and then after few seconds it smooths out. Thanks for any help.

clean the tb yet?
09-25-2014
Sputters as in?
Does it rev up past 1k and then drop down below 1k and then up past 1k again and then down below 1k again like 3 or 4 times?
09-25-2014
Yeah I carb cleaned tb. It's almost like it's lugging. It doesn't rev up or anything.
09-25-2014
you took it off and cleaned it? or did you at lease get the inside behind the flap. cause thats where the carbon is.
09-25-2014
I did not take it off. I just sprayed in there real good.

not good enough. you take the maf out i hope? if not you may have killed it with the carb cleaner. maf should never come in contact with any fluid but maf cleaner.
if you dont want to take the TB off. remove the screen, theres a snap ring around the outer edge, then the screen comes out. re move the maf from the top of the Tb, then open the blade and spray inside, then use a old tooth brush to scrub inside, clean the walls of the TB as well as the sides and back of the butterfly blade.
then take a rag over the tooth brush, spray, and wipe clean with the rag over the tooth brush.

I'd rather take it off. So ill go that route and get new maf. Bc I new better but I didn't think about it at the time. The car has 170k so it's probably due for good cleaning.

buy a new gasket first, and junk yard mafs are best and cheaper then new aftermarket mafs that dont work well at all.
most used mafs are like 40 bucks tops, jy, or ebay.
did all this start after the tune up and tb cleaning? if so, car off unplug the maf, then fire it up, see if it runs better like that, if so the maf is bad most of the time.

I'm not for sure if it was b4 or after. I'm thinking it was b4. So a new maf is a bad idea you say.
09-25-2014
no after market mafs, oem only, aka acdelco only. new those are not cheap either.
im running a 40 dollar used maf for the last 5 years now.
09-25-2014
Rite on. Thanks a lot I'll try to do that this weekend. I got to do valve covers and elbows also. So ill add that to my list.
09-25-2014
the tb will be a breeze then.
oh the maf is bolted in with torx security bolts. you need a special socket to get the bolts out, or cut a slot across the top of them and use a flat head screw driver.
how i got mine off. i used a grinder with a thin cutting wheel, a hacksaw also works well.
09-25-2014
I think it's a t27? Or t26 or something bit
09-25-2014
I got a whole bit set for any security type heads. No problems there.

That's not the right MAF for a 99 GTP. At least that wouldn't fit on my 99 GTP. A new AC Delco MAF for mine off ebay was 150 something. That's the cheapest. So i went to the yard and picked a used one up for $22. I'm happy with it. lol
I need to take the TB off of mine soon and clean it out. Mine takes a few cranks to start and then sputters (acts like it wants to die) for a few seconds when it does start. So maybe my TB needs a good cleaning.

Wow, my bad. I was unawares that they stopped making them out of 18K gold on the later model years. Sorry to confuse, was not my intention.

I just had this same issue with my 99 GTP. I pulled the TB and scrubbed it clean. Scottydoggs is right, don't waste the cash on a new MAF, the junkyard ones typically work just fine and are a lot cheaper. Save the money for more mods. Anyways, after I cleaned my TB and MAF sensor (with MAF cleaner) and re-installed them all, my issue was resolved. Its worth a shot. If it doesn't work, then at least you have a clean TB and MAF sensor!

Rite on, good to hear. I haven't had a chance to clean mine.
