I've had the catalytic converter changed, and it seems to be kind of stuttering at take off. I clean out the throttle body yesterday and it is running significant significantly better. however, there is still hesitation on take off and also it kind of stutters a little bit until it gets to about 60 miles per hour. I have changed the spark plugs also and Z coils.r

Hi,

Can you identify what type of fluid is leaking?

If you cleaned the throttle body and it made an improvement then I would suggest cleaning your temperature sensors and air flow sensor. I attached a guide on how to clean a mass air flow (MAF). So use this process to clean each of the ones on your vehicle.

I also attached a guide on hesitations. It will take you through the basic items you need to check out for this issue. Let me know what you find and we can go from there.
