wtf is up now?
ok, this is a little weird for me but im sure u guys should have no problem diagnosing this one....
when the car is idling i put my foot on the gas and rev her up to about 1800 rpms and hold it there, now keep in mind my foot is completely still not changing the rpms, but wait! whats this?! the rpms drop about 3-400rpms to about 1400rpm and then shoot back up to the starting 1800...this will continue to go on for as long as i hold the accelerator still, and yes there are some drivability issues with this, like rough engine performance throughout most of the rpm range, the egr valve is new and pvc and the iac and tps are new as well, wtf is the problem? please help its greatly appreciated lol!

I agree, you can't get much info with a plug. Just because you just bought all those new items doesn't mean they're still good, test them and make sure they're good just to be sure. Another thing, check your basics, Fuel,timing,compression. That should get you on your feet. Also let us know how the car was running before this happend, or maybe you done something in the past that could have related to this in the future? Good Luck

let me ask you guys something though, could this problem result from the car needing a tuneup? because the thing is i dont wanna go out and spend hard earned money on stuff i don't need and im sure you all understand that.
