SOURCE: POOR GAS MILEAGE

Have you changed the fuel filter? I know it sounds weird but a plugged filter will make a truck use more gas. The computer tries to compensate for less fuel by commanding the injectors to open longer. Also a plugged filter will cause excess back pressure on the fuel pump making it loud.. Good Luck.

What can I do to help fix the hard starting of my 2006 nissan altima


If you have done all the usual tune up stuff, check to see if holding the gas down a little helps. If so, could be a dirty/sticking idle air control valve. Other possibility is bad coolant temp sensor telling the ECU engine is warm when it is not.

How to reduce high rev in engine when accelerating


Assuming you have an auto transmission, your only choice is to ease off the gas when you want it to change gears. Then apply slight pressure on the gas to continue to accelerate.

What are the signs that the engine speed sensor is bad


If you are using more gas than usual I would be checking the air mass sensor on the hose between the air cleaner and your throttle body. From what you describe being hard to start and running erratically . Sometimes they can be cleaned with an air mass sensor solvent. Be careful not to try cleaning or touching the sensor with anything other than the spray. If on visual inspection the bimetallic sensor has not cleared it will need replacing.

7.5 gas eng in 1995 F 350 ! When you accelerate real hard the AC blows out of the defroster ! Got me whupped !


Hi,
Most Ford products have vacuum actuated control valves in the heating and a/c system. Ford designed a fail safe system into their cars and trucks that if all vacuum is lost that the system would default to defrost so at least your windsheild would stay clear. Typically there is a canister under the hood mounted to the fender well that looks like a metal tomato juice container from the 60's. That cannister is the vacuum reservoir that is supposed to hold the vacuum under high load (heavy acceleration) conditions. If that "tomato juice can" is either disconnected or if the check valve in the vacuum line is bad, then whether you are heating or running the a/c, under hard acceleration air will come out of the defroster vent. Check all your vacuum lines running from the intake manifold to that canister and back to your heater and a/c system for cracks or leaks, Also check that the check valves in the vacuum lines are in place the right way (they should only flow one way- toward the engine.) Listen under the hood when the engine is running for the hiss of a vacuum leak. Fix any leaks that you find. I hope that starts you off in the right direction.

2006 Jetta TDI, TURBO Problems


the turbo is a variable vane type where the vanes in the exhaust shell around the turbine are moved to give maximum gas flow at low engine rpm
these vanes rust in the housing and do not move easily when the actuator is energized by the vacuum solenoid
the vacuum hose goes hard and cracks , actuators suffer from wiring problems
basically check that the rad that controls the vanes is free moving and that the hoses and wires are in good condition

2006 saturn ion .car started idling really rough and had no power. Almost stalled out. Had it tested and it said small vacuum leak and misfire. So I replaced the gas cap with an OEM cap and it is still...


Not to sound rude, but when it says "vacuum leak", it means from the intake manifold. Get a can or two of Ether, and start the engine. Have someone run it at a steady RPM. Spray the ether around the manifold, and any hoses under the hood, until you hear the engine rev up. Spray along said section until you find the issue. Replace the offending part. As for the misfire, this should cure that, and if not, try simple things, IE, spark plug replacement, etc.

When someone unplugged my idol air control valve my transmission started changing hard


there is supposed to be a vacuum line between the transmission and the engine that tells the gearbox about load. when its disconected the gearbox will shift hard and the engine will idle lumpy. Find the hose and reconect it and your problems will go away.

Panel vent closes on acceleration


You have a vacuum loss - it is due to the vacuum hoses being removed for what ever reason and now they are crossed. This condition is not bad but it sure must be annoying. Please -take down your vin # - go to the local dealer - [ you do not even need to own the automobile to do this free] - ask the dealer parts department for a copy [ print out] of the vacuum hose diagram. ALSO - ask about RECALLS - this alone has saved people thousands of dollars.
best of it -
