Iat ?
 

Is the IAT sensor a duel connection with the MAF or is it called something else on the DX?

the IAT is inside the VAF. If you look inside, it's the little yellow knub at the top of the opening (the side where your cone filter adpater would go)

there is no MAF on G1 Protege's

thank you sir
 

much obliged partner
