Suggest you look on the drivers side of the engine in the front, there is a black metal guard that covers a pulley that drives the water pump. Make sure the belt is not broken and that the water pump turns freely. Have the cooling system checked for exhaust gases, That is the way to check for blown head gaskets. Is there any coolant in the oil? The Northstar engine is designed to shut down cylinders one at a time to protect itself when overheating. Hope this will help you.

1999 Ford Taurus keeps running hot


Does it get hot mainly when parked or stopped at a red light or does it get hot even when the car is in motion?If its only when your stopped,the cooling fans are probably not working due to a blown fuse,relay or bad fan motor.If the coolant inside the reservoir seems to boil once the engine gets hot,that can be caused by a defective radiator cap.A blown head gasket will also cause overheating.If you let the engine idle for a few minutes,shut it off,pull all of the spark plugs,see if any plug or two adjacent plugs are wet with coolant, that's a sign of a blown head gasket.If you constantly need to refill the radiator with coolant, that's another sign.

My 07 forenza had a code come up saying misfire on 1 and 4 plug so I replaced coil pack now it's reading #3 misfire and has a sluggish take off.Any ideas are appreciated


The sluggish take off is most likely due to a misfire. Pull the spark plug wire on cyl#3 and hold it over an engine ground. It should spark constantly with engin cranking/running. If spark is present..... most likely a bad spark plug. However, there are many more things that can attribute to a misfire but this is the most common

First, have your ignition timing checked. Have also your EGR checked. if this (EGR) is not functioning properly, engine will lose power. If your engines has a distributor, checked for cracked cap, excessive play in the distributor shaft, and other damaged components. You may want also have your ignition unit and coil checked. Don't forget to inspect the spark plug cables.
For the high idling speed, have it adjusted to specification and look for sticking throttle linkage.

2005 dodge caravan sxt engine missing


I have run into these caravans burning oil, not much you can do except keep an eye on the oil level or spend a lot of money having piston rings replaced.
The best way to go about finding the misfire would be to go to an auto zone or other auto parts store that will scan the computer for codes. the codes will tell you which cylinder is misfiring.
I would bet it could be a fouled spark plug due to oil burning but could be a plug wire also.Have the codes read and find the cylinder that is misfiring and remove the spark plug and see if the tip is covered or worn down, if it is then replace spark plug and you may want to do them all. up to you.
If the plug is okay then move on to spark plug wires, swap the misfiring cylinder wire with another cylinder and see if misfire moves if it does then replace the wires.

To find the cylinder by #. If you are standing if front of the van looking at engine cylinders 2,4,and 6 are in front, closest to radiator from left to right. then cylinders 1,3,and 5 are at the rear also going left to right.
Good day.

Esteem 1.6 misfiers until it foils spark plugs it is worst when cold or in traffick


All this happened after you had an overheating problem? Maybe some internal damage in engine? How hot did it get? Extreme overheating can cause damage to the piston rings caused it to burn oil, that would explain it running rich, and fouling out plugs. Also running hot can cause valves to warp, which it turn would cause misfiring. To start off I would take a compression check and see what condition the engine is in. It is a little hard to recommend fixes because I don't know how hot the engine got, or that is part of the problem at all. Please rate my answer so I am rewarded points for it.

Hi, recently my radiator cap came off (maybe I didn't screw it on tightly enough, girl strength) anyway the car started to rev (in a surge kind of way), I stopped at a gas station and left it for 30mins to...


Try replacing your spark plug wires. It is probably just misfiring, which will cause the engine to "surge" and then back off. This will repeat until the misfire is fixed. I would start with replacing the spark plug wires, and if you have any more problems, let me know. The radiator cap coming off would have eventually caused the engine to overheat, but it sounds like you didn't let it get that far. The spark plug wires may have gotten wet due to the radiator cap coming off, and now the spark plug wires are shorting out worse than they probably already were.

Intermittent misfiring


Had the same thing. The didtributor was going bad. Lived with it for a few months finally it died. 1 year after replacing the distributor the problem started again. Glad I got a warranty on the distributor. Running great now on the second distributor.

I have a misfire and the plugs r white i drive a 2001 honda crv


If someone put the wires on on in the wrong firing order pattern or one or more of the plug wires are bad the engine will misfire. White residue on the plug is probably due to the engine running hotter than normal caused by the misfire. Try replacing the spark plugs and spark plug wires.

Check engine light


A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.

The engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the the problems were faulty fuel injectors. 

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.
