Default Smog inspection

Im in need of some help. I have a 99 firebird 5.7 ls1 with a cam that im not sure what spec is it and i need to pass smog. I have cats and o2 sensors but i was told that there is a possibility that there needs to be 4 o2 and 2 were deleted off the computer. Any tips to be able to be successful in smog?

Were they deleted out of the programming so no codes show up? Does the engine complete all its self checks or are any Incomplete or Pending status? Usually inspection places will be looking for codes present, not sure if they will scrutinize the data enough to count the O2 sensors to see if the front and back sensors are present?

What location? Different states etc do things various ways. Some states also check the tune to see if its a stock tune. If your in one of those states the car will probably have to be restored to stock with stock cam to pass.

Need more information. Does your car have stock manifold or headers? If headers what type long or short? Do you know if the rear 02 sensors were physically removed.

The typical OBD2 emissions scan involves scan looking at OBD2 Readiness Monitors and there are several of them.
  • Catalyst (CAT)
  • Heated Catalyst
  • Evaporative (EVAP) System
  • Secondary Air System
  • Oxygen (O2) Sensor
  • Oxygen Sensor Heater
  • EGR (Exhaust Gas Recirculation) and/or VVT System
  • Misfire
  • Fuel System
Likewise, many states don't care if the car is ~20+ years old if the car can still pass OBD2 emissions scan

im in california and i had gotten pulled over and now i have a state ref on my shoulders to deal
with. It’s possible that the rear o2 were removed when last owner deleted that mufflers, but o2 sensors appear when i checked my ses light. I recently bought a whole stock exhaust system with cats and o2 sensors already in it.

California started checking for modified tuning in PCM/ECM this year.

Car will probably have to be returned to stock cam, stock tune, stock manifolds with working rear O2's to pass. With the stock tune the typical aftermarket cam doesn't run well and have too many misfires and fail.

Maybe a performance shop in Cali can help with suggestions.

How much does a Tesla battery cost?

tesla-battery-replacement-cost says...Tesla battery replacement cost varies depending on the labor and parts needed. Typically, the most basic battery replacement in tesla costs between $13,000 and $14,000. For the Model S premium sedan, replacing a Tesla battery costs around $13,000-$20,000. Model 3 entry-level sedan and Model X premium SUV battery replacement can cost at least $13,000 and $14,000 respectively.

Also, you may have to pay around $20-200 for replacement parts like wiring and connectors. The labor charge may cost you nearly $175 per hour. Always be ready to shell out a few more dollars in additional labor charges if the repairs are complex or have any problems with the replacement.

*****

A lot of 2013-2014 Tesla's are priced $36,000 to $45,000 so a $14,000 to $20,000 dollar battery replacement would really really really $uck.

~73,000 miles seems to show upshoot in the adds I've seen. Is 8 years or 80,000 miles about the life cycle of a Tesla battery 🔋?

I haven't seen any 150,000 mile Tesla's never mind 250,000+ mile Tesla's listed for sale. You do see that with 250,000 mile Toyota, GM, etc vehicles for sale.

You don't have to replace the battery most of the time. The battery is made in modules and can be repaired, starting to be more and more shops getting in to this business.

The battery has a 100K warranty. Mine is two years old I've lost about 2% of the range, not counting putting a bit more aggressive tire which cost me about 7 miles range out of call it 200 average. I have a 2wd Standard range + which is a 250 mile battery, but that's with no A/C-Heat and conservative speeds. Its best speed is about 65, 75 and up and it starts to eat up a bit more charge..

Like any other car the independent support levels are growing. I've seen about a half dozen 200K + mile Teslas on the forums, many are over 100 and doing fine.

I find the electrics make a great commuter. Better than ICE in some ways. I am in no hurry to get rid of my V8-LS Jeep wrangler or My 911.. They both provide capability/experience the Tesla doesn't. I also have a Chevy Spark that my daughters drive around. 80 miles range and they can afford to charge it, they both prefer the electric to gas, mainly because it can charge at home and even the spark gets them all over town fine and they have figured out the whole charge when ya can logic. Also you can park the Spark anywhere..

Thanks PDX.

I like my 40v battery push mower, 40v leaf blower & 80v weed eater a whole lot more than expected. Might even give an EV a chance in ~10 years who knows

And when everybody jumps onboard with EV's that's when the cost of electricity will skyrocket. Pretty sure the grid cannot handle such a thing either.
