Glad it's running well again. The CEL you still have is for p0420?

Yes! I had that one! I didn't know if I really had it or I was confused.

Many people say that Hondas hate aftermarket cats, but the $86 that I bought for my Accord has been fine for a couple of years.

There are some very inexpensive services where you can send in your fuel injectors and have them flow tested. I've considered doing this with mine.

Mechanic said he soaked the injectors in a cleaner over the weekend and was unable to clean them. Some bad fuel or sediment made it past the filter.

The car has no Catalytic Converter now so I have a P0420, (no smog test on a 24yo car.)
I'd like to replace it with the later EX style manifold to pipe to converter exhaust setup instead of the original manifold directly to converter style.

The one-piece design that requires replacing both if something goes wrong? What could possibly be a drawback with that?

Replaced the AC fan with one from the junkyard.

I made an Airdam with L brackets.

Upper and Lower grill blocking. Might change the lower, sticks out a bit.

Yes, a different material, even plumbing pipe insulation slipped onto the horizontal fins in the lower grill, will be less obtrusive, more stealthy. It's too bad we aren't all close enough to do meets and share skills and materials. I have a ton of that insukation and extra coroplast and the flat black plastic I used on my grill blocks.

1999 Acura EL is a sedan like the big brother 1996 Civic sedan

Greetings,

I created a new thread to share the modifications and results on my Acura EL 1.6L.

"1999 Acura EL or Civic EX sedan - dropping Cd from 0.33 to below 0,20"

The car improvements over the 21 years I have this car went through 5 phases

1. Finding out the car was actually eco-friendly
2. Searching for means to repeat the best mileage reported
3. Mods inspired by products claims and performance magazines and forums
4. Mods inspired by solid advice : EricTheCarGuy and Autospeed.com (J.Edgar)
5. Aerodynamics mods supported by trials and monitoring data

Mechanical and aerodynamics modifications done to save gas

Modifications testing and instrumentation

Preliminary results for 2020

Using the “throttle stop” method to measure speed increase resulting of mod, results are when computing against the estimated Cd=0.34, for Acura EL 1.6 L, 1999

Adding all the estimated reductions per modification comes to 52,2 %

May be or may be not a real total reduction, if “may be” then means a new Cd= 0.17

Welcome!

Real

It's an interesting thread, but Forum News and Feedback is for what it says on the title.

Rather than advertising in someone else's thread, you could PM the mods and have them move the thread to General Efficiency or Central. It would get more views there.

I believe they would leave a breadcrumb/symlink [Moved to...] in News and Feedback to point to the new location.

Upper grille block could look better

Your upper grille block could look better.

The upper grille is easy to remove on this Civic. Just remove the grille and block it with black choroplast on the back. Use some good fabric tape to make sure the chloroplast won't move and voilà! Nobody sees your upper grille is blocked.

The lower grille is somewhat harder to block aesthetically. I sort of went from the center of the opening where the license plate use to be. Choroplast or aluminium painted black and good fabric tape around the top and bottom edges to the plastic bumper cover did the job. In need, I can remove this lower block.

Until now, the engine coolant temperature never went above 200 Fahrenheit while moving in above 90 degrees temperature days. When stalled in traffic or going uphill or with heavy load, the coolant temperature goes higher than 200 Fahrenheit but the thermostatic fan comes on and avoid higher temperature and eventual damage.

To read the coolant temperature, I use TorquePro app with an Android phone getting data directly from the ECU through a OBD2 Bluetooth adapter. 20 US$ max.

Good luck with your mods,

Real
