Hi guys I have a 2000 Acura TL with an assload of miles at 280000+..How do I begin..I've had this vehicle since 4/2015. When I got it I had to replace the spark plugs, coil packs, clean egr ports..directly after egr ports were cleans I had a CAT code so the Cat was replaced. After the Cat was replaced the car stopped shifting properly. Replaced TPS again last week and car is shifting fine. However I started to have throttle response about a day or two after..I check TPS calibration it was good. I clean TB and replaced TB gasket, I replaced valve covergaskets, cleaned EGR, cleaned IACV..Problem is low idle, erractic sputtering coming out of tailpipes at idle, and no response from throttle. I have to sometime press throttle again as if it didn't register the first attempt...I don't know what to do..I do have a P0132 code for O2 sensor..Im lost guys any help is much appreciated

 

I had a similar problem......I kept throwing a check engine light after I partially replaced my exhaust system. I needed to replace both of the O2 sensors. Haven't had a problem since and it's been about a year.

 

Thanks for that info...What's crazy is I have been ignoring the OBD 2 codes P0132 and P0131...I am going to replace those today after work and see how I'm running then..thanks

Those codes for O2 sensor should never be ignored. They will cause many different problems like in your case and wreak havoc on the fuel delivery/throttle systems.

You should be golden after those sensors are replaced!

 

No problem.....let us know how it works out for you.

 

Changed the upstream O2 sensor with a bosch and the engine code went away and the engine light. However I am still get the low and poor idle on WARM START only...The car is not sputtering during take off on warm start like before. I did some research into "heat soak" where the gas in the fuel rail vaporizes and causes rough start and idle on warm start which is exactly what im going through..Have you guys experienced this?

 

That's a fairly common thing as it starts to warm up outside. How long was the car off before you tried to restart it?

 

The vehicle is usually off when exhibiting those symptoms 10-45min then there's the rough idle, misfiring, critically low idle...As off late as the weather has began to warm a little heavy vibration and misfiring on acceleration above i'd say 65mph
