vaccum/idle problem

[AgntorangeDSM]

i have just recently put on a new Dejon BOV on my 1g and now i have idle problem where it seems to run between 850 and 1050 rpm's and my vaccum will read 10?? i have done a leak test and have found zero leaks in the system if any one has any ideas to help that would be great!!! thanks

When was the last time you got your timing done?

a few month's ago....

another note to add is that when i bought the car the bov was vented to the atmosp. and so when i cover the vent tube of the bov it seems to run stronger so i'm starting to steer towards that being a great deal of my problem.

I checked the timing and adjusted it a little bit it was around 6-7 and i put it at 5 on the dot and i also re-circulated the bov and all is well with the vaccum part now but i drove it around the block and the idle went from 780 to 840 to 550 to 600...... not i'm confused is it my ISC now ?? i'm gonna check the termminals tomorrow and post the results

maybe your computer compensated for the old bov...try resetting the ecu?

If your bov is runnn to atmosphere, it is throwin rich air into your mas and throwin everything off. Mine is doin the same thing. I am fixin to buy a gm complete maf, it will fix everything because it is after the bov and in the intercooler piping. good luck

well i don't have it atmosphere any more and the is really low so i think the isc is not kicking in especialy when i turn the head lights on it just lowers and doesn't come up and for some reason on my s-afc my throttle % will say 2.0 or lower unless i tap the pedal a bit...
