I have a 97 chevy tahoe. I changed the spark plugs, wires, distrubutor cap, rotor. About 300 miles later engine light came on. I thought maybe cheap distrubutor cap and rotor was cheap. I went to auto zone and got another one. Engine light came off on free way. Came back on later on that day. I checked compression test was good. Only miss fire on cylinder 6. So I changed plug and wires again. Still engine light is on. You can on tell the miss fire when your at a stop sign or going slow. Also I

2000 dodge stratus keeps stalling it fires right back up sometimes, other times it takes some cranking. There are three codes it's showing P0725 engine speed sensor circuit, P0108 manifold absolute pressure sensor voltage too high, and P0700 transmission malfunction present. I also pulled the first spark plug out and when the engine runs it misses and sometimes stops all together for 1-2 seconds. I'm broke and can't afford to run through 4 possible solutions.

Just changed spark plugs, around 150 miles later noticed a sputter or mis-fire between 45-60 mph. pulled the plugs when i got home, no obvious issues with the plugs. problem continues to persist and the truck is progressively running worse. the check engine light just now came on. runs rough at idle and all the way through highway speeds. removed all the 10mm bolts to the coil packs and pulled each out one by one. even swapping the packs that were thought to be bad. getting an intermittent spark

Low Vacuum For the last 25,000 miles (currently at 192,000), my engine has had a miss. I replaced the spark plugs, spark plugs wires, distributor cap, and rotor. I also replaced the EGR valve, ignition coil, and fuel filter. There is still a miss. It is most noticeable when the engine is cold. I drive a 1994 Chevy K1500 4.3L V6, AT. I did a vacuum test and the dial read 15 inches Hg. I don't know what Chevy says it should be, but that sounds low. My question is, is that low? If so, what are comm

1994 Mitsubishi Diamante. I had this problem for a while now. When the engine is hot it gets worth. The engine is miss firing, I replaced spark plugs and wires a year ago. i also replaced Air miter. The car does not miss firing all the time as i said. It only does when the engine gets hot or when it is like 90 F temperature outside. When it idles it misses a bit . for every 2-3 seconds interval it misses one random cylinder. I have checked the wires while engine is running and they send the spar

I have a 2002 model manual Ford Focus. The best way I know to describe what it does is "acts like there is water in the gas". It starts losing power and has a really bad miss. It will finally quit pulling at all and I have to pull over, turn the car off, and sit for a minute or two. When I start the car back, I usually have to rev it and then it will go for 30 or even 60 miles before it happens again. This has happened 3 or 4 times. I have changed the coil, spark plugs and plug wires. (al

Won't start My 1992 Lexus SC300 will not start. It turns over like it is going to but never quite gets there. There is spark coming from the coil but the spark plug that I pulled does not seem to be firing. The plugs and wires along with the cap and rotor were just changed less than 1000 miles ago. I've tried a new coil, cap, rotor and even the ignitor module. Still does the same thing. Any ideas?

I just gave my 2001 dodge ram 1500 a tune up, new spark plugs, wires, cap, and rotor. it ran well for about 3 days on the fourth day it started miss firing and threw a code. I didn't get the code number but the diagnostic machine said it was a radom miss fire on 3 and 4. I have put a new ignition coil on also.
P0303, P0304? check the routing of the wires and make sure they are snug at both ends. See if they are routed too close to the engine or any other ground point. Did the old wires have any covers or conduits that you did not reuse? You can probabl ... 2001 Dodge Ram 1500 Truck 2WD
97 Toyota Camry Has been having issues lately. First it started to miss fire a lot kept getting the code p1300 so i was advised to get a tune up i did that.

'91 miata 60M miles - all of a sudden the engine runs very rough at low RPM's and when idling. New fuel filter didn"t help. I cannot detect any vacuum leaks. New spark plug wires and spark plugs at 30M miles.When I accelerate to 2500 rpm's in Park the engine runs very smoothe. In drive there doesn't seem to be much response to throttle from "O" to 30. Just a lot of missing. I have not toyed with any of the settings. I have also replaced the PCV recently. The car ran fine at that point.

Low midrange power and very poor acceleration. I replaced the air filter and spark plugs, checked the wires and they looked fine. It pulls out ok and bogs down at mid throttle, then if you keep applying fuel it picks back up. It will also miss and run poor if you let off the gas slightly. When I pulled the plugs they looked like it's burning a little lean, but maybe that's normal.
Check fuel pressure/filters and airflow meter. ... 1999 Saturn SL
1997 ford expedition 190k miles. Engine was missing. code said it was miss firing in the third cylinder. Replaced all ignition coils and sprak plugs also fuel pump. After 100 miles it started with the same symtoms? What else could it be?

E250 V8 5.4L van with 8 individual packs on spark plugs. I have 2 cylinders misfiring and have change both packs on those cylinders, still miss fires. Also changed the EGR, no difference what so ever. In addition, installed 8 new plugs and the van still runs with a miss and has no take off power. The one thing I havent tried was cleaning/replacing the mass air flow. What else could be causing the issue? Any suggestions would be very helpful. Thanks! Ed

I changed the spark plugs on my 2004 Mazda6s V6. The car idles great and is smooth at highway speeds. Really anything above 2K rpm it works great. When it tries to accelerate between 1400rpm and 2200rpm it seems to miss fire now, but it never did before. I used the recommended NGK Iridium plugs, any thoughts on what could be causing this? Also, it doesn't always is fire in that range, but about a third of the time it does.
Distributor cap lol...check plug gap, the plugs come pre gapped, but they aren't just used for the mazda 6. Be careful not to break the ground electrode or the tip. ... 2004 Mazda 6
