Hi guys! I'm back. I've having an issue with my 2004 Acura TL. I brought it to the mechanic yesterday because I feel my car shaking at stop sings and stop lights. Mounts are new; they were changed back in September. I advised him that car shakes A LOT in the morning when I first start it; really hard start and rough idle, after the idle drops to normal operating temp., it stops the shaking. However, the idle on my car while I stop fluctuates up and down causing the car to shake. I think my idle is off and may need to be adjusted/reset. Can anyone give me some feedback or help on this issue? Perhaps I can do it myself?

Thanks!!

 

what the mechanic say?

 

It could be a lot of things:
- loose spark plug (easy to check)
- dirt in EGR valve causing the valve not to close (easy to check)
- dirty/ bad fuel injector (less likely)
- valves substantially out of adjustment (less likely)
How many miles on the car?

Any codes?

 

my vote is EGR valve

 

EGR and fuel injectors. I clean mine every 30K or so with a can of Sea Foam automatic transmission treatment added to the fuel. Always a noticeable improvement in idle smoothness.

I rarely get on the gas with my car nor do I routinely go above 3K rpms.

 

^ any exhaust mods? I can barely stay below 3k. Assert my dominance through noise.

 

Perform an idle relearn procedure. Involves unplugging the battery for a bit and reconnecting it; afterwards, start the car and let it idle till its up to operating temperature (rad fans turn on twice). Make sure all electricals (radio, AC, seat warmers, lights, etc.) are turned off while performing this.

 

The mechanic said the car is fine; basically it's old is what he told me. The car had 96,500 miles on it. Not a lot actually, considering it's an 04. I performed a fuel injector service at pep boys which helped a lot with the hesitation, however after a few weeks the hesitation came back. I'm not sure if maybe I should perform an engine flush? Maybe that would take care of the shaking and hesitation? My mechanic also told me that my I need to have my timing belt/water pump changed. I was also told that I should have my valves adjusted; maybe that would help the issue? Thanks for the feedback everyone!!

 

Car read NO codes at all. He told me the car is fine... but it's not running the way it should.. Not sure ...

 

Also, not should if it could be my idle air control valve..? Does my car even have one??

 

Looks like you never bothered to read my post.

 

I actually read everyone's posts.. I can read, I'm not blind.. I did what you suggested and it didn't do shit.. so I should have not even read it in the first place.. thanks for nothing.

 

His method was literally the easiest thing to do, wouldn't you rather try this than clean a bunch of stuff. 9/10 resetting ecu improves shifting and idle

 

headers but I live in the cities so rarely an opportunity to romp on it. on my trip to MI I did nail it every time left a toll booth in IL on I90. I am at 134K and that seafoam is great...

 

and make sure you have radio and navi codes

 

You didn't bother to mention that you tried it and that it didn't work.
