Just because the springs were new when you got them doesn't mean they couldn't be getting weak.

im having a similar problem. idk what it is. i had replaced my opti and valve springs (they were bad) but now when it goes above 6k the engine will feel like it looses all fuel for a sec. i back off afraid to blow a hole in my block... idk wtf it is.

May be a noise issue. Television and communication channels which have been opened and boosted now are interfering with ignition. I've debated lead sheet metal shielding. at least wrap the ECM or something.

i called my tuner. he doesnt think the play in the rotor would cause the tune to be off that much but the tune might still be off. i need to go back for a retune to do something about my gas mileage anyway so ill have him take a look at it while im there. anybody else have any suggestions?
