sorri to be kinda off topic but can coils actually make ur idling rough? if it were coils, will that rough idling happen at netime? and sorri one last question. what are coils and what do they exactly do? LOL thanks

Weird! I recently flushed/changed all the fluids (and changed the plugs) in the car and noticed the same thing: it seems to be a bit rougher at idle than it used to. Wondering if there are air bubbles in some of the lines from having drained/refilled all the fluids at once.

?

i have a 99 and had the same problems with the rough idle and i had to replace my #3 coil and reset some codes. Now the car runs fine.

whatwasthat

.... what are coils?

1st timer

those things that you have to unscrew when changing you spark plugs,you have 6 of them,3 in front and 3 in the back.

how do i determine which coil is bad

1st timer

if one those things go bad,your "check engine" light will go on.

figueroa1357

no check engine light but still rough idle when driving evreything is fine

acura3.2tLv

How long has your car been like that? My check engine light didn't go on for about a week after the rough idle. Just bring it in to get an engine diagnostic test.

try cleaning your injectors

ricebox

Grab an old spark plug and crank the engine over for bout 3 seconds with the spark plug inserted in to the end of the coil, if you have a spark during cranking then coil is good. Should be very simple if you have 2 people during this process. Oh yea another recommendation for rough idle problems, you should check out BG Products Induction Service, cleans all air passages and cleans out carbon deposits, or you can try a nice can of BG 44k.

two weeks still no check engine

figueroa1357

i tried fuel injector cleaner from autozone still runs the same

acura3.2tLv

What cleaner did you use?

acura3.2tLv

Definitely the way to go!!!

ricebox

BG 44k is not just anyone fuel injection cleaner, trust me its a whole different level of cleaning, it is a total cleaner from gas tank, injector, chamber, catalytic converter, o2 sensor and so on. Trust me big ass difference. Oh yea for you guys out there that havn't had your transmission flush, check out BG's premium tranny flush and fluid. They got a cleaner during the flush and a conditioner additive after the flush. Nothing else out there even comes close. Best bang for the buck!

ricebox

Oh yea to add, BG is not an off the shelf item that could be bought at wal-mart or your local shitzone.

i will try it get bk toyou

acura3.2tLv

I put one can of bg44k in my car last week and all of a sudden it started to die. I asked a mechanic and he said that means you had a lot of junk that was being cleaned out. I have used other cleaners in the past but this one seems to be the best. I would definitly recommend this product..

1st timer

where can i get this bg44k stuff?

acura3.2tLv

ebay for like $17-$20 shipped.

Hornda

does it rev up and down? or just shakes a lot? maybe ur throttle body cable is too loose? make it idle a lil higher.. dunno just my thoughts

1st timer

where else,canot find any on ebay.

optomos

You can also call local dealers like Honda, Toyota, Peugeot, etc... some of them will have it as well.

The main ingredient in that product is naptha. Back in the day with cars that had carburators, they use to pour a little tranny fluid down tha carb and that would eat up the carbon course thats kinda hard to do with a throttle body.(works great for an engine flush to )

This will help with carbon buildup, but the problem you are experiencing would not happen overnight...especially if you had this problem right after you changed the plugs.
What plugs did you use?(make sure they were iridium) Did you reset the computer? (disconnect both positive & negative terminals from the battery for a minute) Also look back over your handy work and make sure you put everything back together correctly. Check to make sure you didn't disconnect any vacume hoses by mistake, which is a taltale sign of rough idling.

optomos

Its what Acura uses instead of a spark plug wire. It fits right over the spark plug. Expensive buggers to! about 70-75 each.

my car has stalled before
