Just installed a new AMC head and its running decent but the engine kinda of stutters and hesitates when initially accelerating. It will do this when just sitting in neutral. And it will run pretty rough when idling under 1000 rpms. I figured it was a vacuum leak but did the carb cleaner trick and couldnÆt notice a change anywhere.

This sound familiar to anyone?

ItÆs a 88 Trooper 2.6L 4ZE1 AMC head

90 Trooper 2.6 - AMC head
