ok so finally my b20v engine started, BUT my rmp are all the wat up to 3k its that cus im using b20 injectors, and it letting pass alot of gas? and if the injectors arent the issue then what do i have to do? ... thanks

jumper the 2 wire service connector on the passenger side kick panle and unplug the iac.

start the car it should idle.

if the car will run rev it a few times and look at the back of the car on the exhaust side and see if it is blowing out black smoke.
if it is then your getting way too much fuel and iac is adjusting for it and making the engine rev and idle at 3K

if the car is still ideling at 3K with the IAC disabled then you have a vac leak.

okay thanks bro!

JessyJDMlover

well i disconected the iac but it still on 3k witout smoke at all!

you likely have a vacuum leak somewhere

JessyJDMlover

the vacuum its the lil tank with the thin *** hoses right?

grjr

a vacuum leak means that air is being let into the engine from someplace other than the throttle body. The air could be leaking in from a leaking gasket, o-ring, or hose. You should check all the hoses connecting to the intake manifold for damage, use an inspection mirror to check the backside of hoses as well.

grjr

you could have an IACV that is stuck open as well

ok theres one plug on the back of the manifold that i it has no hose but idk if thats the problem because its not getting air on it.... but ill post a pic of it tomorrow morning

i think i would first confirm that it is a vac leak.
to do this, just remove the air cleaner boot. start the car. cover the throttle opening. if the car continues to run, it's leaking.
if you've got an open nipple on the intake manifold, that will cause a large leak. try capping it and see if idle changes. a pic of it would help

okay so it was the IAVC and i already fix that problem, thank you alot!!!
Know i have another issue, i was trying to test my car and i gave gas to it but it doesn't run like it does but it stops at 2k rpm's... i keep giving gas and it idles there like if it had 2step... im frustrated and im almost giving up on my car, so before that happens does any one of you know what would be the problem?

el crapitan

i would probably check for codes first.
if none, perform a sweep test of the TPS

there's your problem at 2k revolutions per minutes?? how many minutes does it take to reach 2000 revolutions. solve that problem first.
