make sure the rubber hose going from the airpump toward the engine is not ripped. i was barely failing at 2500rpm because of this. you might have a more serious tear. just guess.

Isn't there a vac chamber that can be cleaned out that helps on smog tests? I read it on one of those popular rotary sites I think.
Yeah, definitely get the cat hot. You may want to run a bottle of those smog pass in a bottle cleaners from Kragen or Pepboys.

Kinda realted will my 93 rx7 pass smog with no airpump apex PFC and cats still on. And a KKK stage one. Also does lowing the boost help with smog. Could i drop my boost to like 5 psi just spring and pass smog better than the usual 10-16? or Am i better higer cuz im burning more fuel or is this a stupid question. I think it might be. Cuz doesnt the boost not affect low RPMS
Thanks

i had a idea, this may be stupid but i cant really think or y. WHat if you disconnected your down pipe from the motor and let the gas run out the top. This might work to reduce smog. what you guys think.

HAve them run your car again. I took my car in for emissions this past weekend, and the car failed on the first try, but passed with flying colors on the 2nd try. The guy told me that the computers that meassure the emissions tends to make mistakes often.
