HELP me with my emission problem....PLEASE
I failed emissions in Illinois and I need your help before my license plate is suspended. I believe it is a vacuum leak but I need to know exactly where I would check.
I have a third gen but this may be a problem that anyone with a rotary can answer. I checked the vacuum on the boost gauge - no prob, I choked the air hoses going to the air filter and it didn't have an effect. I thought the car should have cut off with such a lack of air but it didn't. I also checked the hoses to the ic and found nothing. There has to be a GREAT deal of vacuum being lost somewhere in my system because my idle is twice the number that it should be (CO reading of 3.2 - standard is 1.2). While the car is in idle it pulsates high and low (up & down). This could be a tell-tell sign but I'm only a neophyte at working on my ride. What could be causing so much air to be syphoned-off and where would the guilty culprit(s) be? I also checked and adjusted the idle control and it had no effect. I need you guys help ASAP!!!! It's not cool driving around in a nice looking car that sounds like shit!!!! |
I also forgot to mention that I have relatively new spark plugs and wires (1.5 yrs old). An Apex N1 dual exhaust that's about the same age and a PFS management system that I thought might have been the root of the problem but after I disconnected it, the engine continued to pulse/fluctuate. Could it be the O2 sensor, dirty throttle body, bad temp heat sensor? or there is not enough fuel getting to the engine?
Any help?????? |
