| Stuttering and check engine light [message #484356] |
Mon, 17 October 2005 05:18 |

I was driving my 2001 MX-5 (26K, Red) around with my wife looking at the
Fall colors. The car had been stuck in the garage for close to a month as I
had a pallet of building supplies blocking it's egress. Anyhow, got it out
an went for a nice drive. About 1/2 hour into our drive the car started
acting like it was out of fuel. Almost like the ignition was being turned on
an off. I got to a side street and noted that the car could not rev over
1,500 rpm without intermittently losing power. The check engine light came
on about that time. The car would idle but revving it above 1,500 rpm again
caused it to cut power on and off. After about 5 minutes of this, the whole
ting resolved and the car again drove as it always has. However, the check
engine light remains on now. Again, there are no current drivability issues
but the check engine light is on. Any ideas of what happened?? I hate to go
to the dealer but I guess I will need to have them look at it. No problems
ever before with the car. I assumed it was an electronic glitch. There was
no backfiring, but the on-off power thing was almost like turning the
ignition switch on and off.
Does one have to go to a Mazda dealer to see what happened or can any
competent independent shop help me??
Weird!
Thanks for any suggestions!!
Rick

Anyone with an OBD-II scanner can retrieve and interpret the error code
that prompted the CEL. I think AutoZone will do it for free. Once you
have an idea what caused the problem, you can decide what to do next.

Just for good measure: you might want to get a new set of spark plug wires
while you are renting the scanner.

I just replaced the wires in my '02 SE; be aware that the wires changed
in in '01+ when Mazda went to a coil-on-plug design. There are only two
wires, one is short and one is long, and NGK does not offer a Blue
replacement. I ended up with NAPA Belden wires, which were $50 for
the set of two (!), but made a substantial difference in performance.

i was thinking the same thing... but also the fuel filter and the plugs are
suspect. yet that doesn't explain why the check engine light has stayed on.
it represents so many possible things that only the reader could point you
in the right direction... something is not right. if i had to hazard a
guess i might say it is a faulty coil pack. but if you didn't want to spend
the time and money on dealer diagnostics the i suggest the removal of the
spark plugs to see if they are fouled. plugs are cheap and they might be
all that you need.

ps. regarding the coil pack, this may be interesting reading for you as well
as another way to self diagnose the problem...

The original poster has an '01, which doesn't feature the coil packs
of the '00 and earlier models. Instead, the '01 and later have two
coils which each plug directly down onto a spark plug; the tail of the
coil is fed to another plug with a single wire. I do not know if the
the coil-on-plug coils are more reliable than the previous coil-pack
coils, but my experience so far with an '02 is that the stock plug wires
die pretty quickly.

It could still be a bad coil, of course - I just don't know
how the 'new' coil-on-plug coils do compared to the 'old'
coils.

It cannot have been water in the fuel that collected at the bottom of the
tank while standing?

could be, but assuming that is the reason then comes the question as to why
the cel is still on... could it be that all the misfires have fouled the
catalytic converter so now there is now an emissions problem?

Oops! Originally just replied to Dana:
Okay, this afternoon's update. The check engine light is off and again the
car is exhibiting it's normal (joyful) drivability.
However, I am a little concerned about getting further than pushing distance
from home. I will check the plugs and wires as that seems easy enough.
Should I still do the scanner since there is no check engine light?? Does
the onboard computer store old information? Thanks for all the suggestions
so far. I hope to get this figured out as I had a Black Hills vacation in
mind for the late Spring.

fwiw, my check engine lits regularly came on when the gas tank was between
3/4 and 1/2 full.... the good people here told me to tighten down the gas
cap and sure enough it has not come back since. mine is a '95 so i don't
know it it applies for you, but it certainly did for a friends late model

Yes, a good scanner will show these codes as "pending".
You should do it ASAP because the codes get erased after certain time/car
runs.
Not so good news: OBD-II reader shows "pending" codes but it doesn't show
if they've
just occurred and will light up (CEL or MIL) check engine light
or if the symptoms just stopped showing after lighting up CEL.
So codes are pending > CEL on > pending

I don't think that happens that quickly. Doesn't on mine.

Alright, here is my two week update.
Car is running fine. Check engine light went off the day after this
incident. Have driven 100 miles without the slightest problem. I was going
to take the car to the dealer to have them check it out until I found out
that hooking it up to the computer to see what codes had been stored would
run $99. Found out that I could purchase a new OBD-II scanner for the same
price and took the leap. It is a cool thing and comes with a CD that you
can install on your computer. The CD has the codes, including manufacturer
codes. Anyhow, I plugged in the scanner and found the code that was stored
in conjunction with the incident was P1345 which according to my nifty
computer program is a "Cyl Discrimination Signal Camshaft Position" code.
Any ideas of what might have gone on here? I originally thought it was an
onboard computer glitch. Hmmmmm?
Anyhow, the car is running fine now and the only other action I have taken
is to run a bottle of Techron with the last tank of gas.
Ideas??
Thanks!!!!

I feel your pain.
I have a 2000 that is behaving the exact same way. Only mine has been
doing so for 18 months and has completely died and left me stranded 3
times.
The first time the O2 sensor was replaced. The check engine light came
back on 3 days later.
The second time the cam shaft positoin sensor was replaced. The check
engine light came on 3 days later.
The third time was 2 days ago and I am waiting to hear from the
dealship now. I hold out some hope that whatever it is really broke
this time becasue for the first time the car did not restart once it
had cooled down. The other 2 times it did restart once the engine
cooled down for an hour ro two.
The whole time the engine ran fine, execpt for the 3 times it stranded
me. The whole time the check engine light was on a mojority of the
time, but would go off for a day or so once every week or two.
Anybody else?

I had a 2000; just traded it for a 1990 with a turbo. The 2000 had the
same problem as yours; but, the replacement of the cam sensor fixed the
problem for me.

In my case, (2000 Miata) it would start up from cold, run like it was
firing on three cylinders, I would attempt to drive off (because I was
always caught like this away from home) and after a few minutes of
belching smoke and jerking along with everyone staring at me, it would
clear and run normally for the next several months. Of course the
engine check light would come on but after a few days would go out. The
dealer checked for codes but found nothing. (And recorded nothing, doing
the check at first for free.) After a year or so (and about 3 incidents)
it finally got worse so that the check light stayed on and by this time
the problem had deteriorated until the cat converter had fouled. The
dealer by this time had caught a "random misfire" code as well as the
fouled cat code and suggested it was a failing coil pack (from their
experience.) I was dubious but paid for a new coil pack (because they
had not recorded the problems earlier there was no record so no coverage
by the just-expired warranty). They waited then to make sure it was
fixed before ordering me a new cat converter (covered by the longer
emissions warranty.) No sign of trouble in several months and I am
starting to regain confidence that they were correct and the problem has
been fixed.
