Hi All,
As these Vipers get older, I see so many horror stories in regards to diagnosis and repair of simple problems.
I've seen pretty much everything on these cars, all generations, but specifically Gen 1-3. I'm semi retired now,
but still active in the Viper community. I have worked specifically on these cars in every aspect for 30 years.
Feel free to use me as a resource. [email protected].

Dan,

I am preparing for a Gen 3 purchase and am trying to figure out who to have perform the PPI. It’s especially challenging because I’m searching nationally. With your experience, could you advise me in particular things to have the inspector look for?

I think I have responded to everyone so far. If there is something that will be good info for everyone to see here on the site, please post.

I follow the site a couple days a week.

Hello I own a 2005 convertible with only 12.000 miles,the car is almost perfect condition,alwyas pampered and serviced,has only and aftermarket exhaust system..I have 2 questions first is since like 2 years,on cold starts,there is a strange vibration and a little noise next to that coming from the engine after like driving 10 minutes,and the engine is hot,these vibration and noise disappears.What can be the cause? my mechanic said, it can be the throttle body that needs to be cleaned.. second is front left tire sensor broke 2 years ago so we replaced all 4 of them with an aftermarket,but my mechanic could not erase the lo tire warning sign on the dash,so I even went to dodge dealer service and they could not erase it also,and they said to me they need to rpeplace again all 4 of them with mopar sensors whci cost around 500 $ so I said no,,my mechanic says there is nothing wrong with the aftermarket ones,they are the same only they dont have an mopar sticker...so what is your opinion about these 2 subjects? tahnk you in advance and Sincerly... the car is in florida

I've had similar issues with my TPMS sensors from time to time. I have full aftermarket cloned sensors at this point (they are programmed to have the same IDs as the original OEM ones). However, every once in a while (seems more common when I have the key on for an extended period before starting the car), I will get a constant chime and the low tire light like the sensors are missing or showing low pressure. It will eventually go away if I drive it long enough, but it's horribly annoying until then. I ended up "relearning" the sensors on the computer and that seemed to help, but you need a DRB III to do it unfortunately. The clone ones or emulators don't talk to the TPMS for whatever reason. I never could figure that one out. If you can find someone that has one nearby that might be an easy option to try. I also found my aftermarket sensors do not wake up with the donut style magnet like the stock ones. I had to buy a little TPMS wakeup tool from Amazon. I think it just sends some kind of radio signal. It was cheap enough at something like $15 though.

Not sure about the noise. I know the stock engine mounts are known to wear out, and I could see that causing noise and vibration issues, but I would think it would be consistent. It might run a little rougher on cold start that could lead to mounts moving around a little more, but most modern cars really don't have as much problem running cold as old carb cars did.

I always use the stock wheel sensors. They program quickly and
last many years. I have had issues with the aftermarket sensors,
either not programming or failing when you hit a bump.

As far as the noise when cold that goes away when warm. I would
check for a cracked exhaust manifold, tends to make noise at start up,
but goes away as the manifold heats up and the crack closes.

Vibration could be motor mount related. If the engine seems
rough when cold, the injectors might need to be cleaned.
