this might sound stupid ??? but I have noticed my idle is not smooth.it kinda feels like a miss ,kinda like if you have a cam in it. how do you tell if someone put a cam in without taking the cam out and checking manually? the rpms on the factory gauge stays pretty still at around 600 -700 rpms..then now and then it will drop then smooth right back out. ive done new plugs,cap,rotor, and i did the wire test where at night time i got the car running then took water mist over the wires..well no archs,or sparks so theres no cracks in the boots anywhere.fuel pressure stays at about 38-42 psi at idle. and it is a 5 speed. should a completely stock 95gt idle so smooth where you can hardly feel it, or will you feel some shaking..and yes i do realize it is a V8 :). so im just asking to make sure nothing is wrong..thx

Check you mass air meter kinda sounds like the wires that read the airflow are dirty,also might want to check the Fuel press reg to see if it is leaking through the vacuum hose.

Im not sure how to tell but you can tell by idle usually, but you might just have a idle problem. Clean your MAF as mentoned, also clean your IAC...should make a big diffrence.

38-42 psi at idle is high you should only see that mush psi at WOT not idle unless the vac line is diconnected. Idle should be around 30-32 psi.

dang man you must have some picky ass neighbors lol that was cool what you did with the cop though like everybody else said check your maf , iac and the tps and your timing to see if any of those are off too that will contribute to some weird idle issues
