When the car si warming up for the first couple of minutes there is a hesitation if I give it over half throttle at low rpms. I know my AF is lean could this be the pcm sensing knock and retarding timing? also I have amaf code that says insufficent activity could it be this let me know thanks.

 

I have miss and hesitation also....

I have changed my wires and plugs, and coil. I get a miss when it warms up. If you find the solution to your problem email me at kaylin11@comcast.net

 

have you changed you fuel filter? I had a similiar problem and it was cured with an ORP(cat was clogged), new fuel filter, and new coil. Good luck

 

I havenot done the fuel filter what two sized wrenches do you need to undo the fuel line is it 5/8 and 11/16?
