she has been in the garage for about a month getting the interior redone. got her out on the road this morning for a 45 minute drive to blow her out. ran perfect. then to the station that usually does it. and she didn't pass. he even ran her through twice.

92 Camaro tbi 305 stock engine. headers and magnaflow catback magnaflow high flow cat. custom tune by EAGLEMARK. fuel pressure 12psi. she has passed the two years passed on the third try but the readings were way less. pushed on the egr while idling and she will bog. checked vacuum 21 psi steady. cap, rotor, plugs, and wires only 2 years old. fresh premium gas.
checked a couple a plugs and they are clean.
checked for power at the egr solenoid--14.5 volts. used a power probe and grounded the solenoid ecm wire and I get manifold vacuum on the backside to the egr. sucked in egr valve and it held. hooked all vacuum lines up and hit the solenoid with ground and it will not pull the egr in. maybe its no suppose because it needs backpressure. car does not have the smog pump or the tubes. does have the egr and the fuel tank canister.
let me have all the ideas please!!!!!!!!!!!!!!!!!
