ok so my 93 325i has a slight hesitation around mid throttle but then clears up in a few seconds..ive replaced the spark plugs and when doing so found that a few of the ignition coils where cracked up but not terribly..also im pretty sure my cats are bad due to a rotten egg smell after i get on it passed 5k rpms..
The hesitation isnt that bad you can just notice it when taking off and isnt there everytime..my throttle body boot has a crack underneath where the 2 ports are..the ports are actually whats cracked
seems to happen more when my car is at running temp..also the temp seems to get hotter when it starts acting up more
idle is fine and when the hesitation goes away its fine, no bucking just the slightest hesitation
Just wondering if any of these things could cause a slight hesitation and which should i replace first
