Question about 1997 Mazda MPV

Burning distributer cap

I have Been burring up distributor caps, It stared over a year ago, code tripped for random misfire, and I replaced everything, and about 3 moths later the code tripped and I pulled the cap an router and they where burned, the next few lasted about a month each , last I replaced the distributor(the coil is built into the distributor) but it still burned up the cap within a month. I then replaced again ,and the cap burned up within about 10 minutes of driving, and the distributor got so hot that the plastic plate at the bottom(below the rotor) split. I tried replacing the cap again and it burned up in the driveway. I though I might have a faulty distributor, so I sent it back and got a new one, same problem. I checked all the grounds replaced the battery cables, I have continuity back to the computer, I finally swallowed my pride an took it to a shop who told me there was just too much play in the aftermarket parts(he said it was wobbling), and had me replace the cap and rotor with dealer parts, they burned up in about 10 minutes of idling in the driveway. I cant see any wobble when I have some turn it, I have a feeling its something electrical but I have no Idea where to go.

Most likely the ignition coil or its resistor (the resistor might be [an intergral] part of the coil.

Have another look at your plug wires, and make sure that you have them in the right order. As you probably know, if the firing order is wrong, you can have problems. That is somewhere for you to start, anyway.

Drive it into a dark place, or wait till dark. When it's running poorly, see if you can see any spark flying around. It sounds like plug wires.

SOURCE: 1991 Mazda 626 DX dies suddenly after running for 10 minutes.

Hello, It sounds like an engine ignition control module gone out or a coil. They get hot and quit working after a short period of time, cool off then work again till they get hot.
Is the ignition system pointless electronic or does it have points? Are you getting any fire at all now to the cylinders? Does the tach in the vehicle show any RPM's during cranking? Do you have voltage at the positive side of the ignition coil? Does the coil meet the ohm ratings for that years vehicle ignition? Does the vehicle have oil in it so the oil pressure sensor allows the engine to run, this may not be an option on your particular vehicle? You can check most of this out with a volt/ohm meter. Check your voltages before starting the vehicle, during running and after it quits to see where the loss is. Just don't get near the center tap of the coil or you will get a rude awakening and/or serious injury. Good luck, RAC

I own a 2003 GMC w 6.0 litre and the it throws the code random/multiple misfire I think code is P0300. it's fine for days even weeks before code shows up again. RDP shows on dash can't go over 50-60


random misfires can be from ignition side of things or it could be from fuel side of things
check fuel pressures
check wiring to injectors
check coil/s and ht wires
check ht leads are not touching each other
if you have a distributor cap check for cracks ,moisture and carbon inside cap

Burning Oil


This engine may not be on time. When timing belt was replaced maybe they didn't installed correctly and now is not synchronized (is not on time) this is the main reason engines experience misfire after replacing timing belts. If you take valve cover out and notice antifreeze in there, you have a blown head gasket.

1995 4.3 MISSING WHEN WARMED UP


Is the check engine light on? An OBD II code P0300 - Random/Multiple Cylinder Misfire Detected could indicate a bad crank position sensor causing a misfire. Another possibilty would be the coil or distributor cap. The 95 and 96 were notorious for burning distributor caps. My 96 used to burn one once a month which is why Chevrolet stopped using them and went to multiple coils. More information would be helpful in diagnosing the problem

P300


When was the last time the van was tuned-up? Cap/rotor/plugs/wires? is it a distributer ignition system? how many miles are on the truck? And We have had alot of problems with most caps/rotors until we switched to delco-remy cap/rotor. they are a little more expensive but seem to last and not have to replace them yearly lol. And have you removed the screens that are supppose to allow condensation to escape the cap/rotor? they clog up and cause problems.they are located underneath/on the bottom of the distributer, u can use a small pick or screwdriver to remove it/them.it's not always easy. i can't remember if there were one or two screens on that year/model. But with the random misfire it is generally the cap/rotor, so i would start there. Make sure to Label the wires, cap before removing so you do NOT get wires crossed. Also be careful not to over tighten the bolts holding down the cap because they strip out easily. if they are stripped, try using teflon tape on the screw(s) to help grab the thread. Otherwise you will probably end up having to use a small machine screw with a nut to hold the cap down, it sucks to do it this way.

Had sparks plug changed 3 times, still showing multiple misfiring, engine light on and it cuts off someimes


What codes are stored? are wires all in good shape (tightly connected, not broken)? distributor cap tight and contacts inside good? Knowing the codes would be a good start in where to look for the cause(s) of the misfiring and shutting off. I had a similiar experiences a couple years ago. One plug wire was broken and caused it to misfire when it was raining. The code stored in the computer showed cylinder 2 misfire, which led me to search for caused specific to cylinder 2. Also, later I had my car just shut off while driving. I checked the distributor and one of the clips that hold the cap to the distributor was broken, causing the cap to flop around (and random misfires).
Hope this helps! :-)

Code p0300 coming up random cylinder misfire already changed wires had cylinder 5 misfire .should i replace coil


If you already replaced the wires, I would suggest replacing the plugs, distributor cap and rotor. They are also very important parts of the spark. Fuel injector problems can also cause misfires.

1996 tahoe , codes are showing random misfire


Do an injector balance test and a cylinder leakage test. Lets make sure its not fuel related. Most important lets make sure you don't have a vacuum leak.
