What's the typical life of a stock Viper injector? The engine is tumbling a bit around 2500 rpm and I am suspecting it might be an injector (I have eliminated all of the usual suspects..battery, plugs, wires, throttle body sync, reset ECU, fuel filter, etc.) I've got about 48,000 mi. on a stock '99 engine, never had an issues. I haven't driven with the problem long enough for it to start to show itself on the plugs (it may never). I am wondering if it might be time anyways to just clean (or replace) the injectors.

Injectors usually last longer than engines. They do get deposits that affecting fuel mixture preparation and cause hesitation, stumble, rough idle, etc. Try a $10 bottle of Techron.

Hey Bruce,
I just sent my injectors to RC Engineering in Torrance Ca. They clean, bench test and calibrate all the injectors so they are all equal and give you a report. They even replace the upper and lower O-rings. Takes about 1 day. Cost was about $270.00 + shipping.
My engine ran a bunch smoother after I got it done.

Make sure you tell them that you are a paid club member.

I'm going to say the "calibration" part is misleading. At least by their page here: Fuel Injector Cleaning

Looks like it is a flow/clean/flow sequence. If you have a factory Viper injector that needs a change in flow to match others, then IMO you have a bad injector, not a dirty one.

My procedure is flow/clean/flow. I do the work .... "I" means me, not some hourly paid person. That person somewhere else may really care about the service they give you, I can promise that it is not possible for them to care more than me.
If you by chance had a bad injector, I have spares sitting here.
I usually inspect the o-rings..... if needed, I have lowers and suggest if you need uppers or just want to go back with new ones that you order them from Chuck Tator/ Viper Wizard.
I'll also add, if you are having troubles...injectors or not....I can help you trouble shoot your Viper ;)
Oh yea, for Viper guys it is $120 for the complete set plus shipping.

Plus, I just renewed my VCA banner earlier today :D

Here is my machine ($5,000)
