Yes I had read other posts about scan tools show up to 265 and it still be normal. The scan tool says ect but we know it's not measuring the coolant temp. So after my truck sat while I was at lunch the temp gauge decided to start working again. As you can see my ect says 240s. I saw 262 going...

I go over a mountain to get material for work and after reaching the top of the mountain my temp gauge drops. It use to come back to normal. Now today after flushing the radiator it's deadish. Kinda on cold and sometimes at the 1/4 mark. My ect was reading 250 consistently but the temp gauge...

I emptied the coolant and then filled the coolant tank with water and let it drain. How can I be sure the coolant is out of the heater hoses

not available here

what is the equivelant of motorcraft premium gold that i might find at walmart cheap

okay ill go ahead and drain it all. how would you drain it to make sure its all out of there

when i got this truck it had coolant leaks. there was no coolant in the reservoir. i topped it off with green coolant thinking that was the standard type and Ive always heard about it. now i looked in the manual and see the truck calls for motorcraft gold coolant. googling did not help with my...

So are the high fuel trims under load caused by dirty injectors? Truck sat for a year

I'll do a graph next but here's a picture of how much the 02s b1s2 voltage varies

Yes b1s2 voltage at idle ranges from 0 to .7 v. Under acceleration it shows .8 v but will drop low. The b1s2 percentage is steady at 99.2

Why would mine not be steady

Jumps all around from 0.0 to .88

Fuel pressure is 60 and remains steady with increased throttle. Also holds pressure with engine off

I drove around with my scan tool plugged in and watched the fuel trims. The stft are always close to zero. The ltft will range from almost 0 at idle and go up to 18.8 at 2500 rpms and under load. How is it possible for ltft to go so high and the stft be almost 0 or even negative 1 or 2

See I had been googling this code trying to fix it and so many people had said it's a lean code and means the engine will be running hotter and could damage it because of the lean condition. Most of them said to park it until its fixed. So I've been afraid to drive it. But I thought like you...

I cleaned the maf sensor about 2 weeks ago. They guy before me had just replaced it along with the o2 sensors

Where would I find egr info? 200k miles. 2003 year

I have occasionally been getting p0171 pending codes and now it finally made my engine light come on. Here are my fuel trims when the code was stored. Typically my fuel trims are 0 to 5 whenever I test them at idle and 2000 rpm. This spike that sets the check engine light is intermittent. Is it...

That's what I'm afraid of it being a cracked head. How much would you expect it to cost to get the head and head gasket done? The coolant drops 1/4 inch to a full inch in the over flow tank every 100 to 300 miles.

Truck slowly losing coolant but otherwise runs perfect. I did a combustion leak test and these are the results. The color changed from blue to green. The pure blue in this pic is from my f150 as comparison to the green from my ranger. So I'm assuming the ranger has a small head gasket leak. The...
