The easiest way to see if the computer is reseting at start-up is to look at "starts since reset". If it reads 0 then the computer is reseting. PCM voltage can be checked at the PCM during cranking. If it drops too low you have a supply or voltage drop issue. This is all stuff that the dealer...
This should be an easy fix. I deal with CARB readiness failures all the time. We put the car through a drive cycle on the dyno, then force it to run the evaporative tests. Unless there is something else wrong with the car, its pretty simple.
If the car runs low on coolant, the expansion tank gets pressurized with steam and cracks! Replace the tank, cap, thermostat and a 50/50 mix of new coolant and distilled water.
Hope this helps.
A little exhaust trivia here. We remove the crossover exhaust on the 03-06 models. It frees up a little power and reduces heat.
On the 08-10 models with headers/ with or without cats (track only). We found adding the crossover increased torque by 30 in the mid to high rpm range without any loss...
Mopar Performance did have a controller for the Gen 3 that complimented a MP cam and exhaust package. They also had numerous Competition Coupe calibrations that were loaded for differing tracks and altitudes. These were only available to the race teams.
Hey Folks,
Here is a link to a track car I have in the classifieds. Its like brand new and cost a pretty penny to build. My good friend just does not have time to use it and its been hardly used for years. Great value...
First off, you will get the most benefit from a cam change with ported cylinder heads and a lifter upgrade. I always prefer to remove the engine, although it can be done in the car. With the engine out you can easily degree the cam and figure the compression ratio. It also gives you a chance to...
If you do not have an aftermarket swing pickup oil pan, then I would run an oil that will give you some extra protection. Race oils like Motul 20-50w have a high Molybendium content that can resist bearing scuffing from a momentary loss of oil pressure.
The writing is on the wall when it comes to smog and aftermarket parts. In past years there was kind of a gray area, but now they have cracked down really hard on the smog stations and the technicians are much less likely to look the other way. They could go to jail. California is the worst as...
If you put the car on a rack and look up under the engine you will be able to see the head gaskets sticking out from the side of the head. The replacement gaskets are black MLS (multi layer steel). the original gaskets are brown (composite). They tend to degrade over time. If you service your...
Yes, you can use the stock primary cats and they will work great and flow well, plus they most likely will outlast the aftermarket cats. You cannot package all 4 cats back in the system but you can modify the secondary cats for a 3 inch inlet and put them in the system. Most likely you will pass...
When it comes to brakes the balance is critical and the Viper is very sensitive to front rear bias, more so if you change springs or add Aero. The Brembo stuff is top notch, but I would only run the 4 wheel kit on a Gen 2 as the 2 wheel kit is just to front biased. If you just want looks and...
I have found that if you bolt up the manifold and torque it down slowly the flange with conform back to it's original shape. If your smog issue is with the visual inspection then the manifolds will correct that. If its an emissions failure (CO, HC or NOX) then you have another issue.
You have a 2 1/2 system if you have the stock exhaust. Specify 2 1/2 outlets for the headers. We tested with the stock muffler, Corsa 2 1/2 and 3 inch (with headers), Same results as Mark, power was almost the same with all of them, the 3 inch with Corsa made the most by just a few hp. It was...
These are real tricky but you can use an easy-out tool and hook it to a slide hammer used for body work. This is the only way I have been able to get them out.
