90 gtu rough idle seems like a misfire, popping noise please help
so i just bout this 90 gtu with a few problems. the only one im a little nervous about is that it idles a little rough and im hearing popping noises coming from the exhaust. the idle bounces from about 1000-1300 rpms when it warms up that to me seems like iacv or something but im not sure im just hopping i dont need to replace apex seals or anything right now, and also wen i put it in gear the engine sound becomes much deeper even if im not revving or drivin. any help please!!

Test the TPS: http://howto.globalvicinity.com/gv_w...i=58&co=1&vi=1. Look for dead spots in the range, or if it's out of spec. You can also look for sources of air/vacuum leaks that will make the idle bounce around.
