Nah, if it was a fuel pump, it'd be more than a check engine, the car would run like crap if it was a major fuel system component.
Well, if all your hoses are routed correctly, and none of them are leaking, and you have reset the ECU like I said, and you still get a CEL, here's what you should do next.
1) pull the ECU codes, they will tell you exactly what the CEL is coming on for.
2) there is a possibility that one of the hoses is defective. pull off a hose, put your thumb over one end, and blow into the other. if there are pinholes or cracks in the hose, you will know, since the air will leak out in a spot other than by your thumb. if a hose is leaking, replace it.
3) did you remove the butterfly vaccum solenoid? (the vaccum bit that controls the Intake
butterfly) If you did, just reinstall it, even if there is no butterfly in the Intake
, it may correct your CEL if you reinstall it. I've also heard other people have had this issue when they install an Intake
, it's usually either a hose routing error, or they needed to put the butterfly back on.
BTW, I know a lot of Intakes
come with a little plastic nipple to block off one of the vaccum ports since the nwe Intake
doesn't use it. if that's the case, did you check that too? it could be another source for a vaccum leak. also, double check all your plugs on the wiring harness that you may have disconnected when installing the Intake
, maybe one of them is loose, and it's causing the CEL to come on.
If it were my car, I'd pull the ECU error codes, and do a complete vaccum system check. At this point, I'm pretty sure it's a vaccum leak now from what I've been hearing so far.
is the car running any differently, I.E. rougher idle, hesitation or anything like that? if it's only the CEL, I'd say that it has to do with how the hoses are routed, or possibly a butterfly removal (but the butterfly only applies to the GTS)
Don't sweat man, we'll help you figure out the problem regardless of what's wrong.
BTW, have you tried e-mailing Injen
about your problem? tell them that your check engine light is coming on, what type of Intake
and car you have (incluting thansmission type and model year) and they should help you fix the problem. also be sure to tell them what you have already done to try and correct the problem. they may have an updated install guide for your application.
