I just had msd ignition put in my car. I thought it would fix the miss and hesitation in my car . It didn't! Here's what it is doing, when you start and take off it acts like it's hesitating even if i hold the pedal to the floor. After about 1/2 mile it will clear up and run fine, there's no check engine light coming on. Someone told me that it is the fuel regulator. If you have any ideas please let me know. Thanks

 

Need some basic info about your car:
-year
-model
-engine
-any major mods
-tranny info (for future questions)

Put this info in a "signature", so it will post automatically at the bottom of all your posts. Left click on "User CP" on the red task kbar at the top of the page, then click on "edit signature". They built F-Bodys for 36 years, with numerous engine variations, so we need to know which one you are asking about.

Also, provide the details of the "msd ignition" components - coil, wires, Opti (if its an LT1), whatever.
