Please note that I have not driven the truck yet as I have to replace a few rusted brake lines after I get it running correctly. Test the injector you think is bad is by swapping it between cylinders. You can find this chart in the vehicle service manual for your particular model, which is available at many auto part stores. Low compression could be caused by a blown head gasket, cracked piston rings, a crack in the cylinder wall, worn valve seats, and essentially anything else that would allow air to rush out of the cylinder. I don't have access to an engine analyzer and would like to avoid taking it to a shop if possible I hate other people working on my truck. Doesn't sound like one but do think there might be a compression issue? Sometimes when I push in the clutch to shift, the engine will rev up to about 1500 rpms and then start surging up and down a few times before it gradually falls to normal speed.
I performed an intake cleaning with throttle body cleaner though the intake while running and with seafoam through a vacuum line. Mega Vacuum leak search several times. Go with a 20lb or go up to something else? Any coolant like water turns the oil into milky brown if excess and tastes sweet. If you were racing, then it might be worth a matched set. I found the platinum plugs don't last, the electrodes on mine wer tiney and could not hold the heat. The other injectors made a loud clicking sound but I heard nothing out of 3. A muffler shop will usually check it for free! Back pressure from the exhaust disrupts the combustion process and puts strain on the the engine and causes misfires.
The specific coil pack for your truck should look similar to these. Test the injector you think is bad by swapping it between cylinders. You can try fuel injector cleaner. Retarded timing also means low vacuum especially if the engine is popping through the exhaust due to the timing. Shopping at a quality, affordable auto parts retailer like AutoZone ensures you save time, money and a whole lot of hassle.
Random or none on level ground. Maybe pulling the plugs will tell more about what could be going on. They're the only part in the combustion chamber that's easily removable. Any ideas on what to look for or how I might further troubleshoot this problem? Thanks for the suggestions, I am looking forward to more. This article applies to the Ford F-150 2004-2014 and the.
I noticed you said the truck had sat for 2 year. Engine oil pan gasket leak results in the engine oil accumulating in the Ford F-150 exhaust system. This problem is only in closed loop. Replacing the filter should help sort the problem, but if misfiring persists, this can also indicate a faulty fuel injector. Every now and again at idle, but very seldom. New fuel filter as well. Hope this helps let me know what you find.
The engine does not use oil or antifreeze. Antifreeze leaking into the spark plug tubes or intake manifold will result in an engine misfiring, too; although in this case, you likely also have a blown head gasket. When you state replaced everything in ignition was coil replaced? At about 140k I did replace the injectors on mine. Here are four likely engine-related issues. I got the engine running but it has a performance problem??? Is your truck consistently misfiring? Note if the symptom follows a pattern and occurs when the engine is cold, warm, at every stop, during acceleration, when traveling at 30 mph or after 50 mph. Can anyone help me out here??? A logical approach helps when you are facing a common problem.
Almost allof them are not to serious really. The blue nozzles are injectors. By - November 19, 2014 Contributors: This article applies to the Ford F-150 2004-2014 and the F-250, F-350 Super Duty 2005-2014. Now the bad one was pretty toasty and had wet gas on it. There's all kinds of things it could be.
Misfires happen for several reasons, but most of them relate to the delivery of spark, air, or fuel to the cylinders. It didn't use to do that so I know it has more power. There are endless stories of decreased performance when plugs not specifically designed for a particular engine are tried. Does your truck feel like yourself on a Monday morning after a weekend of partying? So far I've replaced the coil, distributer, cap and rotor, ignition module, and plug wires. Last but not least, seafoam won't fix bad gas.
Clouds of white smoke are not the sign of a healthy truck. Replacement of the pan gasket is easier and recommended than mending. Depending on its capabilities and level of sophistication, a scan tool will retrieve trouble codes, read operating parameters when a symptom occurs, register engine operating conditions in real time, and test actuators and other components. It also pops through the exhaust and has already ballooned the muffler somewhat. If adding cleaner helps but the problems return, you can try having the injectors cleaned at a shop.
First I will start by changing the plugs, then the wires. Below are some of the most common problems you may face as a Ford truck owner: Ignition Coil Failure Figure 1. First things first, get that old ass gas out of there. You are currently viewing our boards as a guest which gives you limited access to view discussions and access other forum features.
