I was wondering what type of fuel injectors the 2004 TL uses. Peak and Hold or saturated. And what are the CC? I think I need to replace them.

When I start the car, it will idle fine but when I drive off, and reach the stop sign at the end of the street, the idle drops below 1 and stalls on me. Every once in a while, I will get the check engine code p0302 saying that I have a misfire.

I thought about the seafoam but I don't think that will help.

I have 83k miles on the car. The last 20k all freeway.

Thanks

 

Misfire on cylinder #2. Could be a bad/loose coil pack, could be an injector, could be spark plug, could be worse:

Google is your friend.

 

80k miles -I would change the plugs out with NGK Iridium (same as stock) and run seafoam (before plug change) thru the intake manifold and gas tank.

and buy 1 coil- try it on each cylinder till the car runs right, thats the most frequent cause of misfire code. BUT there may be a TSB on this issue at the dealer

If changing the plugs- the odd looking oil wet one had the bad coil- put the new coil on it!
make sure to reset the ECU so the computer can run self test and relearn without a misfire

Its possible this is covered under the emission warranty- it wont pass smog right now and is under 5 years old--check the warranty, call acura 1-800-382-2238 x5
and go speak to the service manager at your dealer

 

are you using premium fuel?

 

if not you should consider using 91+, I use 93 shell v power and she loves it...

 

The easiest way to determine a coil problem is switch it to another cylinder and see if it codes for that cylider. A valve adustment can cause that as well,but usually isn't a problem until they get over a 100k.

 

Thanks. Yes I am using the 91 octane. Changed the plugs about a month ago. Went away for a little bit but came back. Swapped coil 3 with coil 2 so we will see if I get another code. I also put in a can of seafoam.
