I just did a tune-up on my 4.0, thinking that would cure the miss it has at idle... But, it didn't... I'm terrible at diagnosis, so that's why I'm asking... It idles just fine around 1000rpm (I know that's high)... Once it warms up it drops to 800-900rpm and misses... I thought it could just be needing the tune-up but it still does it after it... Any ideas?
