I also need to know if your truck has a mass air flow meter or not. Logged The right to be stupid is inalienable for sure however, there is no such thing as a right to impose stupidity onto others Great Thoughts will Overwhelm a Feeble Mind There is never money to do it right, but there's always money to do it over. If you have any video material which you want me to use in a next video, please donate it trough video dieseltruckchannel. If you would like use a digital multi meter and a paper clip and test it. Fraud and falsehood only dread examination.
Use the paper clip to back probe the gray wire with the white strip should be reference. I started it up and it read about. I never assume that a new part is alway's good as you can get bad ones sometimes. Albert Einstein Tuning on a Dyno for the track, is like swim practice in a bathtub. Samuel Johnson The chaotic resistance of the opponents leads to the conclusion that they are not prepared to meet the challenge. Or is that possibly why the voltage was so erratic because of using chassis ground as a reference? I would like you to know that I am a die hard Ford man and tech by nature and never had problems with 95 F-150 with 275,000 miles and my 98 Mustang with 115,000.
Doesn't accelerate unless you stick it to the floor and the tranny downshifts. So with meter hooked up you should see with the key on engine off. Let me know what you find if this is good then we will test the map sensor next. Would this 1 input cause such a drastic timing change see last message? I can explain it for you, but I can't understand it for you. Jason The person who says it cannot be done should not interrupt the person doing it. They come both ways through 95.
Shop your favorite DieselTruckChannel merchandise now!! After a couple minutes it started jumping all over the place and I could hear the eng. Whats causing the timimg to retard so badly? If by chance I am looking at the wiring diagram wrong and this wire has 5 volts then check the brown wire with the white stripe. I would first check all vacuum lines and make sure there are no vacuum leaks around the plenum and intake. I will be getting a new switch, I will install and let you know what happens. You have a vacuum pump at the rear of your engine in the middle. Crowds are reactionary and barbaric. A mind is like a parachute it only works when it is open.
There's 12V on the O2 sensor heater as it should be. When it is warmed it should idle about 1000 rpm for about the same then drop to about 750 or so. Ok when it starts up it should be about 1500 for about 30 seconds when cold. I think this issue is solved. The voltage jumped all over from.
The exhaust system was very black. Ok now there is a air charge temp sensor in the manifold on the left drivers side of the engine looks similar to the temp sensor. It doesn't use any oil, if the motor was shot I would expect oil consumption. It was fully warmed up. It is in the middle of the rear of the engine close to the firewall. I could see it drop in resistance when I had it in the sunlight as it was in a cold intake when I first measured it. Let me kwow what you find here ok.
I had to replace both fuel pumps because when I ran off the front tank fuel would return to rear tank and pressurize the rear tank. Otherwise I need you to get you volt meter and you need to know about what you elevation is and check you signal return refer to pic below and get back to me with the elevation and voltage you found there with truck running ok. It will idle fast when you start it up, even when it is warmed up. The wire you will back probe is gray with a light blue stripe on it. Air charge sensor was the same, I removed it to make sure it wasn't full of carbon, it was okay. I checked things twice, same result.
I need you to unplug the vacuum line to the map sensor once the truck is warmed up and let me know if the truck gets richer and dies or just runs the same. Anthing else I should check in the meantime? Get back to me and we will go from there. I am thinking this is our next item to test. Facebook: Instagram: Twitter: Tumblr: Let me know in a comment what you want to see in a next video!! What could be making this thing go open loop all the time? It was a high and very unstable reading, which indicates a very rich condition. Knowledge based on external evidence is unreliable. O2 voltage is not even close.
