I feel like I must apologize to bring you all yet another driveability problem. Hopefully I have overlooked something easy and one or more of you will have a solution(s). 1992 Samurai, all stock 1.3, throttle body injected. When it is cold , and I drive away on fast idle, it runs ok, no problem. as it transitions off fast idle and starts to warm up, there is a BIG flat spot in the throttle. Usually the bog goes away when it is at operating temp and I have full range throttle Love my truck , hate the bog. Thanks, hit me with it!

Give it some new spark plugs, a good thing to do anyway & an easy starting point.
