Bonjour again Viper owners,

Again some question regarding my beloved stock (k&n filters and borla catback exhaust)97 Viper R/T with 94000km
I’m gonna try to keep it short.
My Viper has been behaving strange since last summer. The problem mostly happens after going through stop and go city driving.
Problem is the Viper starts acting up with stuttering, missing fire and sometimes the car even stops....again after doing some stop and go city driving. I tried getting it on video to help you guys diagnose what is happening but so far, I didn’t have the car do it and having someone in the car with me to record it.
While doing the stop and go trafic, idle and temperature is fine. It’s when I’m back to slow cruising speed that the action begins.
When it happens, I depress the clutch and let the car “catch its breath” and sometimes it needs some gas pedal action to help it.
So, my first thought was it is battery related, so I changed my battery this spring thinking it would solve the problem, but it didn’t.
I have a permanent voltmeter in the car and it reads 13.6 when the car is running.
I think I still have the original spark plugs and wires but not really sure, how can it be verified??
Maybe this could help you also, I drove about 100km with driver side O2 sensor problem that I think overheated my cat.
I really hope to find the problem because the stuttering and stopping is scary when it happens suddenly.

Thanks again for you help

Ben
