idel problem!! help!! Reply #3 – May 05, 2007, 07:59:20 PM Any problems when it's under load or just at idle? Quote Selected
idel problem!! help!! Reply #4 – May 05, 2007, 08:01:59 PM If it's just at idle I would be leaning towards a map sensor or mass air depending on your application. Quote Selected
idel problem!! help!! Reply #5 – May 05, 2007, 08:23:56 PM so you think the sensor could be dirty? Quote Selected
idel problem!! help!! Reply #6 – May 05, 2007, 08:24:29 PM what do you mean by depending in my application Quote Selected
idel problem!! help!! Reply #8 – May 05, 2007, 08:34:40 PM It's possible the mass air could be dirty but more likely it is damaged or shorted internally. Take a look inside the meter. See if there is any damage to the little wire inside the little hole. Quote Selected
idel problem!! help!! Reply #9 – May 06, 2007, 02:08:17 PM so how should i clean the mass air? Quote Selected
idel problem!! help!! Reply #10 – May 06, 2007, 02:15:56 PM Don't worry about mass air, you don't have it.Check for vacuum leaks. For instance the line that runs from the passenger side front of the engine bay below the air box to the center bottom of the upper intake manifold. It's a decent sized black rubber hose. Mine split on me and it caused the idle to fluctuate and the car to sometimes die. Quote Selected
idel problem!! help!! Reply #11 – May 06, 2007, 09:47:08 PM Vacuum lines and proper idle & tps sensor adjustment (iac unplugged when adjusting, then plug in when done), check them all. "Proper" idle adjustment fixed this for me, only time its a little rocky is with a/c running but I'm running a very low idle. Quote Selected
idel problem!! help!! Reply #12 – May 07, 2007, 12:19:51 AM codes,, check my diy link for the steps to do so.up and down like that tells me its not gonna be a big ass vac leak but possibly a small one. just take each line one at a time or spray carb cleaner along the lines till the rpm changes. that will help locate the problem.if the motor is bone cold, disable the fan just for a couple minutes to you can hear real well for vac leaks to.i drilled a hole in my fan shround (drivers side ) right perfect so that i can drop a long bolt in the hole that stops a fan blade. just rotate the fan up to the bolt then start. its amazing what you can hear without a fan.or,,,,just take the belt off.as for cleaning,, whats good for stuff like this and computers, dvd's, vcr's ect is Acetone fingernail polish remover. that stuff evaporates and leaves no residue. good stuff. dont use that "non Acetone" stuff, evaps maybe a year from now.:D Quote Selected
