My 94 ZR-1 has been suffering from what started out as pinging between 2000 to 2900 rpm with moderate throttle when fully warmed(closed loop op). Then recently, I am also getting hesitation in 4 th and 5th gear (have'ny tried in 6th) when I try to accelerate including WOT. I am begining to suspect cat clogging up possibly on the driverside (scanner reading fluctuating value on scanner on this side). Any sugestions to check catalytic converter will be appreciated.
I have already replced O2 sensor and knock sensor.
