rough idle question
 

I've got a n/a 87 with about 11k on a rebuilt motor. My idle seems rough...kinda "poppy" with little burbles in it.

I've got aftermarket converters and exhaust, so the sound is noticable.

Any hints on whether this might be a stuck/bad injector?

Thanks.

was your engine secretly bridgeported? lol, jp. Im just in a Jport state of mind after hearing soul assasins car....

No porting of any kind. Stock rebuild on the motor.

I may have a vac leak...two or three times the idle has done a wierd "auto-rev" from 1k to 2.5k and back over and over. I suspected vac leak, but couldn't find it with carb cleaner trick.
