Default Life's a beeeyotch and so is my car sometimes

So I'm driving to the vet with a rather unhappy kitty in the car and my car starts shaking at idle.... and I get the dreaded CEL flashing at me a few times. It's running fine under load, just shaking at idle.

So I get home, go to dig up my serial cable to plug my laptop in so I can at least pull a code...... and I can't find my cable because OH YEAH, I lent it to someone at my last job and I got fired the next day.

So now I have to cross my fingers and hope it decides not to fart on my way to work tomorrow..... awesome.

Any ideas? I know I'm stabbing in the dark with a CEL and no way to get a code.

FFFFFfffffffuuuuuuuuuu............

You might need to practice doing this before you are able to do it under 5 seconds.

How to retrieve fault codes.

It gave me a P0304 engine misfire in #4 cylinder.

Which is awesome because our shop is booked for at least another week.

Time to sweet talk my favorite tech and show him cleavage.....

Yay! Another one! Quick question: You have an '05 turbo 'vert, right? Was it an early model with the aluminum intake or do you have the composite?

FWIW, the easiest thing to do is to swap the #4 spark plug and wire with the #1 spark plug and wire. If the code switches to P0301 then you know that your problem was in the plug or wire. Replace both and you should be golden. If not you are on to other potential causes for misfire, like... fuel injectors, intake gasket, etc.

Let us know what you find out. My cleavage hasn't gotten me very far.

Yeh. It's an early one, build date 5/26/04.

I'm just putting a new wire set on for starters and regapping the plugs, I replaced the plugs about 10,000KM ago but can't remember if I ever replaced the wire set and since we have a set sitting on the shelf.....

.....and I'll go from there.

Good start. If you have the aluminum manifold, it appears that they are prone to blow out around the #4 cylinder causing the code. You can test it by spraying WD40 around the seams in the manifold and where it mates the port and if the idle changes you have a leak. I have been researching this problem for months and it appears fairly common.

PT Steve on here pointed it out, but I have checked several sites and at least 4 or 5 people reported back that it fixed the problem and another couple said their problem went away when they cleaned their injectors which surprisingly weren't dirty. You need to pull the upper intake to do the injectors so that may have been the cure there too. I will eventually have to do mine and hope it clears up my P0304.

Even though I haven't driven the car a whole lot in the last few years (maybe 15,000KM in the last three years) that's something I should probably do anyways.

I remember my mom's last car (an Acura) the intake manifold got all gummed up and kept triggering the CEL and I had it back to my shop (an Acura dealer) about five times. Eventually we took apart the manifolds and found all the goo and gave everything a real good cleaning in the parts washer. Problem solved, she drove that car until last year when my dad totaled it by hitting a fence..... which ended up in him getting his drivers license taken away by his doctor.

Morning coffee with the guys here at the shop and we all got a laugh...
one comment was I can hear the insurance agent covering a
fire incident asking "you used what on that car to find a problem?"

May I suggest to use water in a spray bottle instead of a flammable fluid .....

Most people use WD40 (which is flammable) but doesn't cause much risk. Others use starter fluid or an unlit propane torch - the propane gets sucked into the leak and changes the idle. Guess it is dangerous advice, not sure why I didn't just leave it at WD40. Guess I will go and edit. I am fairly cautious and didn't see much problem doing this.
