I’ll ask them to recheck compression after the job done.
Eric, you think the engine still be fine? not plan to look for more problem if everything ok
ERIC,
What do you think I need to have the shop perform engine before I take the car home? do you think perform leak down test is necessary?
I need suggestion before I pick up the car tomorrow on 12/30/2011.
Check Engine light misfire all 6 cylinders (P0301,P0302,P0303, P0304,P0305,P0305,P0306) and P0300 (random misfires) came back again. THIS TIME NOT P0172 CODE.
I though the battle has been over with Check engine light, but I guess not. Tomorrow, the car goes in shop @ 7:30 A.M…. Man, I thought I fixed the CEL issued with test drove the car 105 miles.
What can be? More confuse…
ERIC,
I have replaced all 6 coils with new coils. have you seeing new coil goes bad? I am totally confuse…
Thanks for taking your time to explain in details…
ERic,
I follow your advices, today, I removed the Upper Cover plate and completely removed Intake Manifold off the car again. This time, I discovered the EGR port (big hold) on the Upper Cover plate. To see the EGR port (big hold), I have to remove the metal tube with 2 bolds that hold down the metal tube. I also cleaned the metal tube with spray carburetor. If I didn’t removed the metal tube with 2 bold, I would not discovered the EGR port (big hold). the EGR port (big hole) was dirty, but not completely clog up at all. I sprayed carburetor cleaner and it did the trick. now, it looks clean and no more clog and dirty on the EGR port (big hold) on the upper intake plate. you have to removed the upper cover then you have to remove 2 bold that hold the metal tube (from the right if you stand in front the engine) before you can see EGR port (big hold).
Updated…
So far I test drove the car in highway about 105 miles, the Check Engine Light has not came back yet. Tomorrow, I have to bleed the cooling…and tested drive more to see if I win this battle Check Engine Light.
I’ll share the pics EGR port (big hold) tomorrow..
EGR links with detail pics…
ERic,
Please clear something that I am not familiar on this car EGR passage.
“What I was suggesting is that you remove the upper plate in the intake and clean out the ‘ant farm’ which is the EGR passages that go to the individual cylinders.”
I have a follow up question for you Eric.
When I removed the UPPER COVER there is a gasket, if I understand from you previous message EGR passage on this 2004 Model. I saw there were 6 small holes on the UPPER COVER when I removed the gasket and Upper Cover. I cleaned those 6 holes. ARE THOSE 6 holes EGR Passage?
Or I have to completetly removed INTAKE MANIFOLD to see EGR Passage sit underneath the INTAKE MANIFOLD?
What the EGR passage look like size of the HOLD? EGR small hold or big hold?
Have you seeing the passage that go to EGR valve clog or need to be clean out, too? What do you suggest while I am at the same spot…
Now, I remember that probably forgot to clean out the EGR passage on the Upper intake when I did removed completely off the Intake Manifold. suck… but I did spray carborator cleaner on the passage go back to EGR valve. the hold passage go to EGR passage was not clog up at all. look good but a little dirty but I spray carborator to help clean better.
I did reuse the Intake Manifold gasket…and Eric, do you think it is safe?
Yes, I found 4 bad coil packs. then I went ahead put all 6 NEW OEM Acura coil packs while the car has 136000 miles. if 4 died on me, i think 2 other coil pack will died later.
recaps what I have done so far.
1) replace all 6 spark plugs with OEM from Acura dealership
2) replace all 6 coil packs
3) clean the part of intake throttle where the air filter goes in
4) the engine misfire code still P0172 and all 6 cylinder misfiresnow, I go remove the big intake out and clean as Eric suggested. Hope this will fix.. What else I need to look? Eric, I run out direction to go if I remove the intake completed off and clean. if that not fix my problem…. I don’t know where to go…the car run has power and engine temperature stays in the middle constant.
The EGR picture that I cleaned today. I spray carborator cleaner into those 2 holes and I saw dirty came out… remove dirty and carborator with paper.
Here is my big question… Do you guys think those two holes can be clog up go back up to intake?
the intake was removed and services when the car at 100,000 miles. cleaned everything but I have not cleaned inside EGR two holes. Today, I did sprayed carborator cleaner in those 2 hold picture above..
After I cleaned the EGR, I reset ECM. this time the car check engine light flash 8 times and went off. I went to Auto Zone pull the code, it said I had P0301, P0302, P0303, P0304, P0305, P0306 and P0300 (random misfires).
the code P0172 went away after spray carborator cleaner into those 2 holes EGR.
Forgot to mention, I did clean the EGR itself, too.
Air Cleaner has a big crack… see attached pic.
last pic, body thorottle cleaned today while I am the same spot.
Now, I am confuse what can be other cause the misfires…. Can injection or fuel pressure cause the misfires code?
Updated…
Today, I replaced the starter. Bought OEM Remanufacture starter at Acura dealership price 365.00 with 40 core charges. If I bring old starter, I get $40 back.
When you buy OEM parts at dealer, check online website price and print it out. Most place price match. You might have to talk the guys in part department, and you tell them you found OEM parts w/ cheaper. Possible you can price match, but print a copy to show him so he can attach to his paper work to show proved the price match. I did that, and I got 365.00 list online OEM remanufacture starter… Best deal is be a smart shopper.
I have to say, Acura starter has two bolds to remove old starter. the top bold is easy to remove, but the bottom bold under the starter gave me trouble because two sensors are very close by. If you’re not careful, you can break two sensors because both sensors are very close to the starter bold.
Lucky, I bought Air gun from Harbor Freight and has 25 gallon compressor tank. the bold is 17 mm, so I use air gun with extension 17 mm socket. the 17 mm bold loose, I am very happy. If you don’t have access to air gun, the bold would be very hard to remove because tight space.
It took me 6 hours to finished the job replaced new starter. This is my first time done anything on Acura car. Toyota car is very easy to remove and replaced starter if you have 96 Toyota Camry (don’t buy new starter, you can get Starter kit to rebuld your old starter on Toyota to save $$$ not buy new starter or aftermarket). You get starter kit buy online…easy to do and you save big $$$. All you have to replace two brush inside the starter because they wore out with normal tear.
The car start sound good, and shutoff and remove the key from ignition with no issues. Very happy, but it’s worth it.
I replaced the starter because I can’t start the car. When I tried to start the car, I hear 2-3 clicks but no start. After hit the starter, the start crank without no problem.
Also, today I clean Intake body throttle while everything remove with more spaces. A little dirty on the intake body throttle. I reset the check engine light, took a test drive on highway about 58 miles. The code P0172 came back again.
Tuesday, I am off, I plan to ttake the car in shop to have scan tool freezes live data. hopefully, they can tell me what wrong.
6 cylinder misfires went away. Only code P0172 is still came back.
I hope not O2 sensors or catalytic converter. both items are high $$$…. Does anyone know Acura car has problem O2 sensor or catalytic converter?
Do you have access to a scan tool that can show live engine data? Sorry, I do not have a scanner at all. don’t know a good scanner that support live data and freeze, too.
Hey guys, I forgot to mention today I discover the TUBE, AIR FLOW connect onto Intake body Throttle neck broke about 1/2, but I manage cut small paper cardboard and try to seal around the tear neck that joint onto the Intake Body throttle.
Could this cause code P0172 check engine light come up? P0172 = Lean to rich Bank 1.
http://www.acuraautomotiveparts.org/acu … iew=normal
look at #6 where neck connect to Intake Body thorottle #9 is broken about 1/2 around where you use #9 to tight down with 10 mm.
I went ahead order the #6 because I need to replace anyway because hope this will fix P0172 issue before I bring in the shop on Tuesday.
DO you guys think #6 crack will allow more air went intake body throttle cause P0172 code check engine come up?
DOes my model Acura 2004 TL has MAF (Mass Air Flow) Sensor?
Thank you guys… I’ll update more after the car goes in shop. Keep your suggestion coming….
