no good deed goes unpunished...

Hello all,
New hero on the forum....
I am trying to help a friend who has a 2001 tl with 230K with misfire. 2 months ago I moved coils around and found #6 dead. I replaced coil and she purred. Now all cylinders individually and random code showed up. So back to youtube and I cleaned the top intake / egr channels and the 6 ports on the intake which were completely plugged. Used 3 cans of carb cleaner and 2 hours of my life lol. I also installed new NGK plugs she insisted she bought. Still stumbles slightly at idle when you listen to exhaust. Like one miss every 10 seconds. Good acceleration. She said it ran great that night. A week later she states running rough and eating up fuel. Smell strong exhaust odor outside car now. I said I would look at it this weekend. Oh and she says the motor clunks when she places it in reverse or forwards. (Im thinking oh no motor mounts) lol
This lady is on disability and her father recently passed who would normally help her. I have never worked on or drove in an Acura. I will update as the drama unfolds.
Oh I have a question. To reset ecm you pull neg battery for 5 minutes correct? Are there capacitors that need drained like my Ford Expedition? Thank You

Any chance you checked the operation of the IACV? very common issue. There is a thread here on how to swap it out, or another thread that better yet cleans the existing and save some money because you rarely need to replace it, just clean the valving mechanism of carbon deposits.

Sounds like you have your hands full!

How does the transmission fluid look and smell?

Thanks for the reply. I have not checked that. I have not had much time in front of the vehicle. I found a replacement thread which is straight forward but still looking for a cleaning thread. I will search tonight.
I have a scan tool so I can read the new codes that came up when I look at it this weekend and start the process.

Yes I do! Thanks for the encouragement! lol The more I read about the car the more I'm thinking I am in a pickle... There is alot of information on this forum! This car has 245K

I am afraid to look now that i went to the dyi section and read some post about the transmission. I will peak at it and post. I would think its bad and burnt and neglected. But hey, I could be wrong right? Cause most people take great care of their cars right? LOL

If you want to be a superhero, you could clean the trans solenoid, change the external filter, and do a 4x3 drain/fill. You'd be a better man than I!

You got me at Superhero I understand the 4x3 method since I did that for my Mazda 6. I dont know anything about the trans solenoid. Is that in the valve body? Dont know where the filter is either. I will look into it. Thanks for the Pro Tip!

I have a question about motor mounts seems the front and back mounts are air assist using vacuum. So if the mount fails could that be an open vacuum leak? Thanks for any help

Westfallen, I checked the tranny fluid and it was not that bad. It needs changed for sure. Turns out there was paperwork that states it was replaced 68,000 miles ago. I will start the fluid change process when I do motor mounts. Thanks for the heads up.

I got this done Sunday. I don't know what it did since I did so much work to the vehicle. Runs much better now. Thanks for the heads up.

Glad to hear it's running better ... gotta keep that fluid nice and red.

The vehicle came in Sunday with PO300 301 302 303 304 305 306 and 1399 codes. Searched for vacuum leak with carb cleaner. Even engin mounts.NO LEAKS I removed TB and cleaned MAP sensor with MAP cleaner. Cleaned IACV with carb cleaner. Cleaned TB which was the worst I have ever seen. Cleaned mating surfaces and installed new gasket.
Note: I did find the j traps in the TB air intake hose full of water. About a cup and a half and duct was wet from filter box to TB. Air filer was dry and box was dry. So I dont know where that is coming from. It was alot of water.

Removed top cover of intake plenum and followed up on last weeks cleaning concentrating on the drivers side valley that has the port to the EGR. Rand screwdriver and then coat hanger. Could tell it was plugged. Filled valley with carb cleaner and it bubbled for 30 minutes. Level started to go down. Continued to fill valley. Waited and hour and the pulled EGRV. The flood gates of carbon began to flow. Made a rubber cone to place on air compressor and blew 135 psi thru the valley port with rags over EGR mating surface. Cleanded EGR needle and seat. Installed new gasket and reassembled. Reassembled intake cover and place negative cable back on battery. Car runs good. Has good power and no miss that I can here or feel. Drove car for 5 miles. Ended up with a PENDING PO1399 code.
Used 3 large Gumount cans of carb cleaner and two gaskets. 26.00 dollars and five hours of my life. Motor mounts are bad. Thats next.

Drivers side valley with EGR port

Some of the chunky stuff. This was like the third cleaning. Unbelievable...

Its getting better.

I did not do the mounts. It needs it badly. I am going to get the kit on Rock Auto for all of them since its so much cheaper. I have no idea how to do it so it should be fun....

DEA/MARMON RIDE CONTROL MK5503 Click Info for full list of components. Info
Includes 1 X A4507 (Rear), 1 X A6552 (Front Right), 1 X A6579 (Trans Rear), 1 X A6582 (Trans Front), 1 X A6592 (Front)
61.00. I know they are not OEM but for this car they will work just fine.

Can you tell me where I fill the transmission? The didstick tube is the smallest I have ever seen in my life? lol I have been looking and looking for a description of location or a pic. I read you may have a 18mm fill bolt on the top that is very hard to open but cannot confirm.... Thanks for any light you may shine.
