2001 neon, so sitting at a stop my car idles perfect. but when i go over 5 mph and pull out of gear and coast, my car will idle at i'm guessing around 1500? no tack. all speeds, 6 mph to 115mph... same stuff... any ideas?

 

dude im tellin ya.use seafoam for idling problems.it will fix that

 

Neon have you used seafom? Just wondering,ive seen a couple vids on it,looks spooky when it goes into action.lol

 

dude its amazing.bout time you have a car pic up there man.lol.but if you pour it into your throtle body it works awsome.it burns up all the residue and gunk so it will white smoke while you do it.one of my buddies has a bike(600cc r6)and it cleared his bad idling up like that.best stuff man

 

Its suppose to have a high idle when you are coasting... the PCMs are programmed to do this so that when you shift into gear the car wont stall out b/c of the drastic increase in fuel.... so relax about it.... my car does the same thing cept i only go upto like 1k

 

k so one day i was driving my car and it didn't do it, the next day i drove my car it did... it's only when i am rolling over 5 mph... which tells me that it is not an idling problem, but more likely a sensor or computer malfunction. you say pcm's... what are those? cause i don't want it.

 

You're kidding, right? It's not a problem, that's how your car was designed. The PCM is the Powertrain Control Module; your car's computer. If you don't want it, don't plan on having a car made in the past 25 years.

 

not at 2000rpms...

 

then u prolly have a vacuum line leak... trace them and find the leak... good luck though... those things are a pain in the *** to find.....
