Last week I went to hold the “RESUME/ACCEL” button on cruise control to increase my speed. RPMS shot down and immediately threw check engine line. I cleared the code, it hasn’t come back. Now however when I engage CC It drives fine but every now and then it’ll act like it’s losing power and act as if it’s tapping the gas. I attached this video of this behavior, you’ll see it bounce between 1500-1800 in a split second and it repeats this behavior... 98 ZJ cruise control issues
