Best Vette Yet
Well-known member
I am experiencing an acceleration hesitation issue with my 03, C5, 45000miles, vette. This occurs between 2000 and 2400RPM. It occurs during acceleration from stop or even acceleration on the freeway. The hesitation lasts for a second or two then it clears and the vette accelerates normally. I have been stopped in my driveway and have slowly revved through the RPM range from 700 to 5500RPM. At 2000RPM, the hesitation begins and the motor will not accelerate further. There is a sound, almost like the rev limiter is kicking in. If I give more gas, it slowly goes to 2400RPM and then revs freely above that. If I am stationary and I rev with WOT, there is no hesitation. The only mods I have at this stage is the Granatelli MAF, the Vararam intake and the Corsa Touring exhaust. Any thoughts out there?
