chris42000000: I got a 99 honda prelude which I have a h22a1 which I put in place of
original h22a JDM. I put in new distributor, new cat. New o2 sensors, new
plugs, and have flashing CEL and codes for random misfire and random
misfire on every single cylinder. Yet I don't feel any misfire during
driving? Runs smooth with lots of power and compression.

The Car Doctor: Thanks for sharing!
cairo car: great work many thanks
DJ Wads: Had a Type A misfire and it smelled like rotten eggs too... Replaced the

Mr C: this is a very good video . my sons 96 s10 had a clogged cat which made
back pressure show weak valve springs . The back pressure kept exhaust
valve from closing - sounded and acted like a burnt valve. the mechanical
part of video compression test explained how weak springs read .he saved me
from pulling heads i replaced springs no miss .i THANK you .
Timmy ahoia: Awesome Video!

p0304, p0108, p0122, p1519, p1399, 61-01 and 81-01. Replaced plug wires and

Alberto Lopez: My audi a4 has a rough idle, the shaking goes away when I accelerate. The
dealer changed the coil packs and the spark plugs, still shakes and
recently the check engine light flashes when idling. Anyone know what the
most likely problem is ?????
Bryant M: HELP Please!...
2001 S40 Volvo.
I have two codes P0303 and P0304 cylinder 3 and 4. Rough idle, stall, poor
gas milage, slow acceleration, etc...
Both of these cylinders 3 and 4 are coils, and have to slaves wires for 1
1-4 2-3 I switched coils to see if anything changed. It did not has the
Plugs look "normal", fuel pressure on the line, can't find a vacuum leak,
I have been debating to purchase coils and wires, but they're 150+ and am
not sure if that is even the problem.
Bennie Densmore: I have a 95 Honda accord. My car lights (interior and exterior) flashes
every time I reach 2500 to 3000 rpm. I've disconnected the negative battery
and test it using an Innova 3310 and read a .05 amp. There is know
significant drop of amps. Where should I look next??? .
malaska91: is it possible to have a misfire with no codes showing?
Shafii Zuberi: I
Jose Garcia: Start by checking the spark on cylinder #2 I had the same issue on a Ford
escape, it had a bad ignition coil, get rid of the misfire and then you
will probably have to replace the cat as I did! Misfires kill the cat
jphritz011: Thank you!!
SombraLocs: Can someone help me out, My car is having a Type A Misfire. The check
engine light would start flashing every now and then especially when
driving on a steep road. I took my car to Autozone to get it checked and
one of the codes were P0302 which is a Cylinder 2 misfire and the other one
is a P0421 a Catalyst system efficiency below threshold. Can anybody tell
me what the problems might be and where should I start first? Please I
would really appreciate it.
cadzillals6: When the engine light is flashing, that is a hard misfire. This type of
misfire will quickly destroy your catylitic converter. You need to have it
scanned for codes, any autozone will do this free. Most common causes are
bad spark plugs, bad spark plug wires, bad coils in that order. Let us know
what the codes are and we can try to help.
cadzillals6: Misfire on cylinder number four.
rsanch8695: Thanks Jay! However! My instincts to re do the test at another Autozone
paid off! Obviously the last tech either was not familiar with the
instrument or was just plain lazy or both. The tech at the recent Azone
diagnosed (with the same instrument) a mis fire in the 6th cylinder. So a
new coil wire and plug will do the trick. But the 6th plug is a beast to
get to so here goes the wallet upside down!. Thanks again!
cadzillals6: Daniel, Have you tried swapping injectors to se eif that is the problem?
Need to check compression as well. Sears actually sells a pretty sweet
compression tester for around 50 bucks,
slednck3: my 96 crown vic had grounded out because of stereo harness and all
electrical components had blown and an hour later my cars got a check
engine light and today not moving just idleing i got a flashing check
cadzillals6: Sounds like your fuel pump check valve is leaking. Attaching a fuel
pressure guage to the test port will show if it is. It should hold pressure
xadam2dudex: cars r too complex now days...it's time for electric cars
next492: P0300 check ur engine oil, if it got like chocomilk or diferent color then
it means replaced head gasket, P0171 put new air filter, if it stills there
then change Maf sensor P0442 change the gas gop, try these I fixed in the
past this codes
cadzillals6: You need to test fuel pump output for both pressure and volume.
James Branson: How would a problematic distributor cause a random misfire? I have a 98
Sebring with a distributor that was recently changed and has been running
like crap ever since then. Should I just have it replaced to stop the
Ulysses Gladden: Awesome clear video
cadzillals6: @abaga1299 I would be happy to try. What kind of car and what is going on?

Jessie Taylor: I have a 2008 dodge avenger and the check engine light been flashing the
dealer said it was a blowin head gasket so I changed it now the number four
spark plug misfiring I can take it out and it fires everything could the
catylitic converter be bad ???? could that cause it to misfire???
