Idling too low

1.6 DOHC 2001 Lanos 98,787 Hatch,- what rpm should my standard woo be at right now, its ranging between 500 and 700 revs. could it be my o2 sensor or idle / Throttle Position Sensor

correct idle speed is arround 850RPM

check the TB and intake for dirt and buildups, try an ECU reset... how old is your air filter?

any other problems other than low idle?? got CEL?

how old is your air filter? 1-1/2 month old

any other problems other than low idle?? got CEL? no.

where is the post about resetinng ecu, i will try it
I taken the resonator off and put ascreen inside the tube so water doesn't get into itand it gets better air, i thought that would make it better. but it made only little diffrence.

how to reset the ECU article is in the how to section, what about your intake and TB... are they clean?

no one said removing the resonator will gain you 10 HP... it is still a good mod. taking into consideration that it is a free mod.

well, i looked into the intake and it is dirty brown and has black specs.:
Questions:

1: why is the hose of the cam cover connected to the intake, it is only like a vacume.

2: what to do with that mess, and how do i get it cleaned.

1- this is the PCV (Positive Crank Ventlation) of your crank case, you see... some gases do succseed to pass by the piston rings and start to build up some pressure into the crank case, if their was no ventlation for the crank case the pressure will contiue to build up till an oil seal blows up.

the PCV simply takes the gases that escaped along with oil vapours in the crank case and let them go into the engine to be burned and avoid the pressure buildup.

2- that mess is because of the PCV... oil vapour tends to condense on the walls of the intake and with enough time and distance (100,000 miles as in your case) those condensations forms loads of buildups that causes idling and performance problems.

in the how to you will find an article showing how to clean the TB and IAC... for cleaning the intake itself and the VGIS you can use a can or two of GUNK carb. cleaner to cleanup all the built up dirt and all... i think you can use sea foam to do the job as well... again their is a how to for using sea foam for intake cleanup job.

well i used some carb cleaner and it really didn't make too much of diffrence, and i don't want to use seafoam bc i would probably kill my engine and i can't find any of that stuff when i went to the store. I will use more carb cleaner tomorrow. lately there is black soot on my shiny chrome exhaust tip. frown..

this morning the drive around my block is chilling. Is there supposed to be black water, white smoke and junk dripping out of your tail pipe after you put intake cleaner into your engine, someone please reassure me this is ok.

White smoke is perfectly normal for when you're running injector cleaner. As for the black water, probably it's condensation coming out the tailpipe mixed with soot from inside your tailpipe.

ok thanks
