problems after installing CAI

[Reg]

hi everyone,

ive just finished installing my CAI and went for a drive. First problem that i noticed is that my idle speed changed from 700-800rpm to around 1200rpm. Also theres a orange engine light thing that lit up when i turn the engine on??

how can i fix these problems and whats causing them??
thanx...

perhaps you should state what civic/crx you drive? did you correctly re-attach all hoses etc?

[Reg]

sorry abt that..its a civic 94 vti hatch. yeah the only hose that i had to take of from the old intake is the hose from the rocker cover to the intake hose..

did u put the sensor back in?

[Reg]

yups..the sensor and the hose are put back where they were..

mmm weird prob i've never had ne thing like this, ive changed from stock to cai a few times...

have u tried resetting your ECU ? you can do this by unpluggin the negative terminal of your battery for 5-10minutes and then putting it back in. turn on your car. and let it idle for another 5minutes.

very weird indeed

[ACTI0NMAN-1]

does a knock sensor cause your orange warning light to come on?

[MoDCoN]

so is idle stuck at 1200rpm? or is it fluctuating?

[Reg]

ZCO: Ok i will give that a go..thanx!

ACTIONMAN-1: Nah i dont think so because after putting the CAI in, as soon as i turn on the car, the orange light just came on.. I dunno what that means???

MoDCoN: It fluctuates only a little bit and also u can hear it fluctuate from the exhuast..

Also ive put a VTEC light ages ago, and it used to come on about 4900rpm, and now the VTEC light doesnt light up no more?? and the car backfires sometimes??

ne help??

thanx for the info..

its obviously somethin to do with your wiring then. Did you damage any wireing whiles you were installin your CAI??

[fatboyz39]

try removing the CAI and replace it with the old one. See if that resoloves the problem first.

[MoDCoN]

why dont you check your iacv (idle air control valve)? if your car has done a lot of kays, this might be causing idle problems...

otherwise it might be that you have bumped off some vacuum hoses somewhere... g/l!


are you using the stock throttle body?

[chaos coupe]

go and see ur honda dealer they can fix.. i had the same problem with my old eg too..

[bennjamin]

sounds liek a vacuum leak and a sensor is not reading properly...make sure there is no air leaks and that all wires are connected etc ~ prehaps ur MAP sensor is alittle loose etc ?

[Reg]

Thanx for the info guys..!!

I just had to reset my ECU and that fixed all the probs. The VTEX kicks in when it should...

thanx eveyrone

ur engine check light SHOULD be coming on everytime u start the ignition. its ONLY a problem when it STAYS on.
