Bro pls my Acura TL 2006 doesn't rev past 3000 and sometimes rev past 3000 to 5000, it also jerks after the first gear and den it consumes fuel. I scanned it as it shows some kinda sensor problems

AutoElectNG:


Has your issue been sorted out?
v
Just checking up on you!

yomingr:
Thank you for checking in. Unfortunately I still have the check engine light on after replacing the o2 sensors.I plan to get the defouler to see if it ratifies. Yes the car has gained power on jet off and gear performance is 10/10. the code is still p0420

AutoElectNG:



Good to know.

You were in safe hands then.

If the cat is bad, do you plan to replace it or you are ok with the defouler trick?

POST UPDATED/MODIFIED July 6, 2017

The problem with the vast majority of Nigerian mechanics is not understanding at the theoretical level how things work which is a prerequisite for careful, systematic and high quality diagnosis.

Here is my gift to you - yomingr : if you better understand the process, the system, the sub-systems and the interrelation between them, you will be better able to solve issues that arise when:

If your cat has not been hollowed out, why not try the suggestion in this video:
https://www.youtube.com/watch?v=5icTmYItwiE and read this writeup at the link below so you better appreciate what is going on behind the scenes, a precursor to a repair that will permanently turn the code off for good.

Thank you once again. Did I mention that I did replace the catalytic converter with a new one as well as both sensors! At first, it was the heater sensor that threw a code which was replaced, then the o2 sensor threw a code and it was replaced too. Then after the p0420 came on again. I guess either the converter or the sensors replaced is not compatible. That's y I want to opt for the defouler. And that content "he pored in the tank?"

AutoElectNG:
Next steps - Get the codes.

We will take it from there!

You might have a transmission problem, but further analysis will make it conclusive, until then, this is purely speculative.

How long have you had this ride?

Instead of just copying, you could take a snapshot of the codes when next you meet the guy!

Until then, my hands are tied

kniru:
finally got the codes.
sorry for the long pause, hadn't been around for a while.

Problems of this car include:



2. Prospective client has replaced compressor, evaporator, condenser and pipes. Then returned to change the expansion valve. The A/C was "still not blowing strong" to borrow his words so he was told to get an expansion valve. What happened was that the A/C pipes in the engine compartment are of the right temperature, but the vehicle cabin temperature did not appreciably change. A manual thermostat (actually a relay) was connected to the evaporator since that actual thermostat in the engine was non-functional. When the vehicle is stationary, the introduced A/C relay would switch on and switch off the car A/C every two minutes, but when the vehicle is in motion, it would do this every 15 seconds to 30 seconds.
