Ok, Just recently when I coast down in gear... that is clutch out, no gas and no throttle, the car will start to hesitate/jerk between 1800 and 1200 rpms. Its like the Car will be coasting down smoothly, then at about 1800rpm it will start to jerk, dropping about 100 rpms per jerk. then at about 1200rpms it will stop and get smooth again. THis happens most notably in second or first gear, but I notice it just a little in third as well.

Two things that hve happened to the Car recently: New Cobra wheels/tires, 48lbs per wheel/tire compared to the ~40lbs per of the stock setup. And also I got towed just before it happened too.

any Ideas please??? this is starting to drive me nuts!

 

any ideas/comments would be greatly appreciated!!!

 

JonnyMax I'm not 100% sure on this but when I experienced that problem it turned out to be my Air Flow Sensor Meter. Some techs told me that it was due to bad fuel injectors. But that was not the case. Hopefully this helps.
