The P0171 is a lean condition that can be caused by several things, usually a vacuum leak, or plugged fuel filter, weak fuel pump, or restricted injector.
Does the truck lack power? what engine size is it? 5.4L or 6.8L?
p0171 is a condition based code, changing an o2 sensor will not necessarily fix this concern. it is just reporting more oxygen in the exhaust than it should be.

My car is a 2000 Honda accord, engine light came on checked gas cap,it was ok,shop checked it with machine and code P 1457 came up.What does it mean, & and how do i fix it?


P1457 90 EVAP Emission Control System Leak Detected (Control Canister System) Possible causes
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
It means that your fuel tank isn't airtight. It could be a crack in the filler pipe, a loose hose or even a blown gasket at the fuel gauge sender.
Your car does a vacuum check on the fuel system now and then. If it detects it's not air tight, it throws a code. Now, the gas capis the most common thing. But from the fuel filter to the filler neck something is not right. Look for a small gas leak, stick your head under the car and give it a whiff. see if you smell it, if you have a garage put sheets of news paper under your car over night and see if any leeks drip on it. There's other things but try those first.

I have a 1992 ford f-250 4x4 460 eng. with auto trans with over drive when i give it gas the ac goes to defrost and the trans does not shift i feel it has a vacume leek but i can not find it also the...


I think you are on the right track about a vacuum leak. I would check all those pesky little rubber vacuum hoses that are used for pollution control. They tend to go hard and split if they are over 10 years old, allowing air /vacuum leaks into the inlet manifold which upsets things that are controlled by vacuum such as the vacuum modulator on the transmission. As for the mushy brakes you may still have an air lock in the hydraulic system which would need a complete bleed to fix.

97 safari fan does not blow while on heat, ac, hot, cold any speed, fuse (well labled) is good. Thx in adv.


Check to see if is blowing out defrost vents if it is you have a vacuum leek. The tube is hard to get to take of dog house you will see a group of tubes on connected to a clear plastic junction. Once you get the dog house off one of the tubes goes to your manifold vacuum fallow them its very thin and the engine heat makes it brittle and they fall apart . Mine did same 2 shops 500 dollars and they never found or fixed it used window washer tubing to fix 2 years ago still works great,
