the ls/vtec b18b/b16a in my sol starts out idling at like 1400, then raises all the way up to 2500-3kish when its warm...both the idle valves are blocked off and lines are rerouted, the throttle cable is as loose as it can go, and the tps has been checked several times...as the IM gasket bolts....

the idle doesnt surge, and no smoke from the exhaust....

any thoughts? would PCV valve be the cause? the L-shaped nipple that connects to the IM to the breather box, snapped, and the hose is still on there, but i dont hear any leaks....**** pisses me off...

TIA

what do you mean the pcv is snapped? that is most definitely your problem if it's busted. a pcv is a calibrated vacuum leak.

 

THe L-shaped piece that is inbetween the IM vaccuum line and the breather box, well the - part of the L snapped off, so its more like an I now with the hose connected to it......

 

sure enough, i sprayed some wd-40 near the pcv valve, and all u could hear was a big leak.....time to break down and buy one.....

thanks dude

 

alright, well changed the pcv valve out, changed throttle body gasket, even advanced timing on exhaust cam, and the idle is still messed up.....

it starts off right at 1500 and jumps up to 2500ish with no CEL's or any sign of how to fix it.

what the hell could it be?

 

oh yeah, there is no bounce in the idle at all...it just starts at 1500ish then goes up slowly to like 3k....the only thing i can think of would be a vacuum leak......
