I have a 2000 3.2TL, I have a problem where when I start the car it cranks and turns on but shuts off right away, now if I turn on the car and push the gas pedal down then it will stay on but the engine will shake really hard and bad (happens randomly but most time it starts normal). I had someone pull some codes and it came up with cylinder 1 misfire and o2 sensor. I took it to another shop and they checked with a different computer and he said its the o2 sensor so we changed it (dealership parts) and now I notice the car will start properly but the engine will still shake hard but not as bad as before. What is the problem ?

 

electrical problem maybe? when I was working on my system I had the exact same thing happen. Turns out it was a loose main power wire and ground wire. I think it is a safety mechanism when the ECU senses some sort of issue

 

didnt another guy have this problem and it was his coil pack? maybe like 2-3months ago??

 

I read over a bunch of threads and people had similar problem and it ended up being the coils. Will tell my mechanic to check cylinder 1 as he thought cylinder 1 is the front one.

 

I started my engine and it started to shake pretty bad and the check engine and TCS lights came on. I brought it to a mechanic and it came up with a Idle Air Control System code. He didnt have time to do it today and told me to come back on Monday. How much is it to replace with/without labor ?

 

The IAC is on the bottem of the TB assembly - with a few basic tools you can do the job yourself. Its remove cover plate- clean disc with carb cleaner and reassemble
Stop using the gas pedal to make it start- fix the problem

I would start with a coil failure -
Cyl #1 is the rear passenger side--rear is 123 front 456 as you stand in front of the car looking at the engine
Find a HONDA-Acura private shop or import specialty or speed shop to check it out
for you if not a DIY person
The coil failure is common after a plug change or with enough miles
Buy 1 $50 and move from cyl to cyl- reset the ecu each time- numerous threads on this subject
Codes are CLUES not diagnosis- example multi cyl misfire codes are usually 1 bad coil
The tcs and CEL are just master caution lights in this case
O2 sensor was probably due on age, but a bad coil will throw unburned fuel at the cat and O2- fooling them

A real honda/acura tech will know about the problem- not keep installing parts on a guess

 

If a shop diagnosed and installed the O2 but let it go out the door still messed up- report them and find another shop fast

Any ziners in your area?

 

From these pics, can you show me where it can be ? I dont know how it looks like.

 

it could be a coil pack cuase thats what happen to me but i got three cylinders missfiring

 

There are many posts about the IACV. Check post #9 from this https://acurazine.com/forums/2g-cl-2001-2003-50/check-engine-light-483508/
From the pictures you have its:

 

It stopped showing the misfire codes since I changed the rear o2 sensor. Now its giving the IACS code.

 

That really does sound like your coil. Same thing happened to my 93 camry.

 

The thing is that this doesnt happen all the time, its all random times. So if its a bad coil doesnt it do this everytime ?

 

Hey Eddystone. im new here just picket up a 99tl with 58k original miles. and i am haveing the same problem. it even shut off on me while i was drivring on the highway. i noticed that everytime my tl does this the green key icon flashes.. Please anybody... im stressin rite now.. wondering if car was a good buy..

 

I am still waiting to see what it actually is. Going to change my spark plugs tomorrow morning and wait a week or so and see if I still have the problem.

I think the key light comes on all the time ? not 100%

 

The 99s had a problem with the ignition switches. They go out and do exactly what you're experiencing. Replace the ignition switch and it should fix the problem. There are MANY threads on this exact topic if you want more info. Bottom line, the ignition switch is bad, replace it.

 

How does a ignition switch work if replaced ? where is the original switch ?

 

thanks fgaze... ok. so i have tried avoiding useing the car cause of this reason. i took it for a spin today. and it happened again. it shut off on me again... this time i notticed when i put the key in the on position the green key icon flashes and it takes the dash lights and radio a few sec maybe a min to turn on... this has me stressin... HELP... ANY ONE HEAR OF THIS AS WELL?

 

It's the electrical ignition switch that mounts behind the part you put the key in.

CHANGE YOUR IGNITION SWITCH!

 

thanks fgaze.. can u help me find a part number or a beak down as to what i need?. i have tried lookin around 2 see if anyone has done it, but i cant find anything... thanks again... i appreciate all your help...

Its super easy until the "mystery screw", I havent done this yet but I might if I find out exactly that mine has malfunctioned.

No problem. As for the parts you're looking for, keep an eye on the BlackMarket. There are some good deals to be had once in a while.

 

so i bought the switch.. a little less than 50 bucks. my cousin who had owned a 02 tl did it for me in less than 20 min.. turned on . no problem.. took it for a 1hr 30 min drive local and highway... and so far it hasnt stalled or given me any problems.. thanks Gfaze.... i appreciate your help....
