Idle

[Guero]

well i cant ****ing figure out my idling problem. but i did notice its worst when its cold, but its still not perfect. i was thinking could it be the spark plugs are gapped to low? i think there at .038 whatever was the safest for the nitrous

MAF

oh yeah and when im cruising at 1,500 my car kind of sputters

 

[Guero]

i guess thats the last thing im gonna try. if it dont fix it its getting filled with holes lol

if it didnt do it before your intake then i would suggest a vacuum leak.


but on the shooting the maf comment. be sure to film that

 

[Guero]

i looked for vaccum leaks but cant find any. i know i read somewere on here on how to look for them with something and then see it idles higher for a second or some **** like that.

 

[94gts]

it can either be a vacuum leak or maybe something isnt getting the right amount of vacuum? i think your issue is vacuum related because i had a similar problem last year.

i think what you are talking about is spraying carb cleaner or starting fluid around the vacuum lines and when the idle changes you found a hole.

 

[Guero]

how bout throtle body cleaner? i got tons of that at home.

 

[Guero]

how would i know something isnt getting enough vacum??

 

[94gts]

ya thats the same thing as carb cleaner

Buy a vacuum test gauge and try it out. They're like $20 at Autozone.

A healthy 5.0 should make 17-22 lbs of vacuum, steadily, at idle...mine makes 16 at idle while cold and works up to 17 at idle hot.

 

[Guero]

is there like a vacuum thing that shows all the vacuums lines

 

[Guero]

ok i forgot to say i can hear like a ssst ssst ssst, at idle is that a vacuum line or a header?

 

[94gts]

vacuum leaks are usually a hissing sound

vacuum leaks are usually a hissing sound

An exhaust leak would most likely sound like a metallic ping.

 

[Guero]

so its a vacuum leak then?

 

[94gts]

ive only said that for like the past 4 posts

 

[Guero]

lol thanks im gonna take it the dam shop since i cant find it. i changed the MAF, ill see how it acts mañana lol

 

[SeventyMach1]

You can do that, too. But what's cheaper? Taking it to the shop .... or getting a vacuum tester? Even if you still can't find the problem after testing it, you may need the tester in the future. Be optomistic.

Thanks SeventyMach1!

Dude, get a damn vacuum tester...
