Topic: warm up cycle question

95 yj 2.5 liter
i have a lumpy acceleration when i first start my jeep. after warm up it is fine.
i assume i have a sensor out since i think that different sensors are used during the warm up / running temp.
any input would be great! thanks

If I am not mistaken, during the warmup cycle, it goes to the default programing, as the O2 sensor is not yet taken into consideration...  Could be the reason.
