SOURCE: 1999 Mazda Miata Problem

I have driven Mazdas for 25 years, and am sharing these experiences in case they can help anyone.  I had two RX-7s and then bought a 2004 Miata a year ago.  The Miata really was brand new, a showroom car with minimal miles on it--truly mint, and a true dream come true.  
It ran perfectly but the 'check engine' light kept coming on.  The owner's manual lists four possible reasons:  1) fuel tank level being very low or approaching empty; 2) electrical system has a problem; 3) emission control system has a problem; and 4) fuel-filler cap is missing or not tightened securely.  
Given the car's brand new condition, and since it had a full tank of gas courtesy of the Mazda dealer, I could rule out 1 through 3. That left the fuel-filler (gas) cap.   I had driven the car minimally the first month, so the gas tank was still almost full when I took the car back to the Mazda dealer.  When I was instructed about the importance of making sure the gas cap was secured tightly, I said, "Interesting you should mention that, since I haven't touched it since I bought the car, so if it isn't properly affixed, guess who did it?" and laughed.  I asked if it was a "software" glitch between the updated software used in the shop's system checking equipment and the fact my car was three years old. That resulted in a stunned look.  I barely had finished a small cup of coffee when the manager came to tell me everything was fine.  The answer about what was the problem was vague, at best.  Zoom-Zoom, off I went, and the 'check engine' light hasn't appeared since then.  I do find the gas cap difficult to manage, especially in the winter.  
The Bose CD player died last week, but that's a different problem!  G-R-O-A-N.  
I am a huge fan of Mazda.  Of course the RX-7s had the rotary engine and the Miata does not, but there are similarities.  These cars dislike condensation.  I am in the northeast where winter temperatures reach minus ten or lower, and where summers are very humid.  
I went through the spark plug changes and all else with the first RX-7 when it seemed to have a problem misfiring, or not making a solid connection.  It had a manual choke, so starting it was easy, but after it was warmed up and ready for takeoff, it would perform as if it had a short or dirty plugs or something.  
I was religious about having the oil changed every 2,500 to 3,000 miles, very important. When it seemed the car was misfiring or just not connecting on some level, and everything checked out perfectly mechanically and electrically, I decided to try two things.  First, I only used the best gas.  Expensive, yes, but the car performed better and got better mileage.  Second, I always kept a bit of dry gas in the tank, all year round.  When I had the second RX-7,  I lived near a lake and there always was heavy mist and condensation.  If I kept dry gas in the RX-7s, they didn't have a problem.  If I forgot, the response was chugga-chugga-chugga, cough, spit, hesitate, misfire, and generally behaving like a misfit.      I should stress I ONLY am talking about dry gas, sold everywhere in the northeast during the winter, even drug stores and supermarkets.  There are tons of additives on the market that claim to do this and that and I never have used any of them.  
We love these cars because we feel one with them.  They are so beautifully engineered, we notice every nuance, every single thing that seems a tiny bit off.  The best advice I can give anyone about these great cars is to trust that knowledge, and to be persistent if you know something is not quite right, no matter what someone tells you to the contrary.  I wish everyone as much joy as my Mazdas have brought me . . . now, on to that Bose problem . . . how I landed on this web site in the first place.

SOURCE: misfire after tune up

Since you have a misfire, the fuel in that cylinder isn't burning. Are you sure you have the firing order correct. Also try using one of your old plugs and wire for that cylinder and see if it works. If you only checked for spark at the wire, you might just have a faulty new plug- it happens.

SOURCE: multiple cylinder misfire detected

Thank you for all the information. I don't see how you made it worse unless the injectors were not installed correctly. If you remove them you are suppose to replace the o-ring on each of them and oil them (the o-rings) before installing them. I would check the air filter and the CAT (for excessive back pressure. Also check the rest of the exhaust for damage. If a pipe is kinked or flattened it would need repair. Also GM's are known for some issues with there e-vap systems. You may want to check it out. The gas cap, charcoal canister, vacuum lines. Well good luck.

My 2003 isuzu axiom shaking but no engine light

If the engine was misfiring the check engine light would be blinking and fault code would be recorded. So you need to look elsewhere for the source of the shake like front end and tire problems.

Jeep grand cherokee crankshaft position sensor replaced but still given a weak spark

the coil. ? older post.
the PCM reports even one drop out of 10 , on the CKP or CMP sensors. 99.9% of these changed are good.
why not tell me what you have,? full symptoms and evidence.
got P030x misfiring? are you even using a scan tool,? or working blind.
may be its the coil.?
can can you feel the misfiring.c
can you see the engine shake? all of this is evidence.
do not miss out on that.
does the scan too shop pending misfire codes?
stored codes, or codes while driving, learn to use the scan tool.
do a 60k mile tune up yet?
your engine is not COP coils like the V8
its COIL rail that is a COIL pack with 3 coils inside
that runs 2 sparks each called WASTED park.
so did you try new sparkplugs(dah)first then new coil pack wires HV
next , then a new coil pack last.
start with the cheap spark plug and wires, (called a tuneup)
then pop for coil pack./
misfire can be clogged or leaking injectors too, and that ill skip
with out you using the scan tool fully.

What are the signs of bad spark plug in toyota avalon 2000 model

Vibration while braking usually points towards warped rotors which you will probably have to replace along with pads at the same time. As far as engine performance, you probably want to get a full tune-up. A good tune-up consists of spark plugs, wires(when applicable), induction cleaning service, and a new fuel filter.

Car shaking, no acceleration, check engine light on

Year make and model ??
You would need to have the computer scanned for the trouble codes. Was the engine running ok before you replaced the plugs and wires ?
Could have crossed two wires to the wrong cylinders ?

I have a 98 grand am gt 3100 6 cylinder the problem is a couple of things . when i turn on car everything is fine it seems but if i put it into reverse it shakes or in drive. nutral it dont shake ethier....

First, when was the last time you had a tune-up ? sounds like old worn out spark plugs or wires, you could have a bad coil, I believe there are three on your car, check the spark by removing the wire from the spark plug and the spark needs to be blue/white (not yellow), the reason you start at the spark plugs is to trace the problem, if you have weak spark at the plug and good spark at the coil then replace the spark plugs and wires.

Second, if you run the brake pads to the rotors it will sound like metal to metal and stopping isn't good at all, remove the front and rear wheels and check the brakes, might want to rotate the tires while your there

My jeep just started acting up it raddals and shakes when i push the gas and pops when i go around a curve and push the gas i have no power goin up a hill goes so slow. Anyone know whats wrong with it

Sounds like you might have bad spark plug wires, nothing a tune -up wont fix, spark plugs, spark plug wires, air filter, and gas filter, not knowing the year of your car, also check distributor cap and rotor,good luck, hope this was very helpful, happy 4th.

2004 lincoln nav...shaking..trying to cut off...mech said 3 plugs and wires need oto be changed...can I do this or should I do A complete tune up?

There haven't been Tune-Ups,in the last 30 years,on vehicles that are all electronic
You have COP, Coil-On-Plug Ignition System,no plug wires
Spark plugs and Air Filter and other electronic cleaning, is called preventative maintainance,and as I said, that way for decades.

If you have Codes PO-301 thru PO-308,you may have a bad coil or two. I doubt you have three bad.
Their $59.00 at the auto parts store. Install them yourself

The only tuning that is done,is by the PCM (computer),not a repair shop mechanic

Also,scan the Throttle Position Sensor,they fail. You can get that at the store also,and don't need a dealer to sell you the entire throttle body for $700.00.

Clean the MAF Sensor ,with CRC MAF Cleaner

Expect the EGR Valve to fail.

Change your trans fluid, flush your power steering fluid and brake fluid every couple years.
