Sensor??? A misfire is usually caused by spark plugs and wires. After that you change distributor cap(if equipped) , fuel injectors, check for proper compression.
Go somewhere and have your timing checked.
If cylinder 3 on a Ford Explorer is misfiring, it might be possible to fix it by changing the coil pack for that cylinder. The spark plug might also need to be taken out and re-gapped or replaced. If neither of these options work, the spark plug wire can be checked.
it depends on what kind of 6 cylinder but it can be the module the coil packs or the distributor It's on a '96 V-6 Pontiac Firebird. I'm thinking it could involve the ECM or an injector could not be pulsing. But how do I check and fix both?? I changed my coils on my 98' Camaro three times, they run about $35.00, the number 5 and 6 cylinder coil should be the last one when looking under the hood right over the right valvecover.
have you checked to see if the timing belt or chain is broken? have you checked cylinder compression? is the oil up to proper level?
Did you only check one cylinder? If you only checked one, you may have just by chance picked a cylinder that was misfiring. The most likely reason to have unburned fuel is if that cylinder isn't burning. Check ignition and compression that cylinder. But I would check the other cylinders first. A misfire may also explain your engine's poor performance. I checked the compress in the cylinders 125-130 psi is that good?
Try changing the spark plugs and have the timing checked.
I checked with AUTOZONE about this and it is in the tank. Another way for Toyota to get you in their shop to charge you money.
I would also like to know where the data link connector is on this so I can check for any codes
you have burt up your altnator get it checked at autozone for free
Have you checked the spark plug wire for that cylinder,??????????
Have the cylinder head checked. Probably a crack in the head. That is the problem i had 2yrs ago. part was about 300.00 at autozone. Dealer may charge about 2000.00 to repair.
The 5.4L engine uses a coil-on-plug system to create the spark for each individual cylinder. I have heard of an instance where both coils went bad at the same time on a V10 Ford Engine with the Coil-On-Plug system. One thing you can do is have your Trouble Codes scanned (Auto parts stores usually do it for free if you don't have a scanner of your own) and find out what cylinders are misfiring. Then, swap the coils of the two misfiring cylinders with two coils of cylinders that aren't misfiring. After this, have the codes checked again, and if the misfire trouble code jumps to the 2 cylinders that you moved the coils to, the coils are both bad. If the trouble code indicates that the original two cylinders are misfiring, then the problem is elsewhere... Your V8's Cylinder Arrangement is as follows: Firewall 4 - 8 3 - 7 2 - 6 1 - 5 Front of Engine
