My 1992 chevy g20 van surges and i'm not sure exactly why. I changed the pcv valve, fuel filter, spark plugs, and air filter. What are some possibilities


My first thought would be a vacuum leak in one of the hoses. Rubber hoses get brittle with age and even a small crack in a hose may cause surging. Happened to me in a Lumina.

Hi It is almost impossible to get my 86 1.6L Nova to start after being shut off for several hours (overnight) I put a new fuel pump & filter on which didn't help then put an electric pump on. Still...


Under hood fuel lines, touching coolant or heater hoses.
Fuel lines under vehicle close to or not shielded from exhaust pipe, converter, muffler. Fuel lines pinched or crushed.
Fuel filter changed recently.
Fuel pump pressure. Fuel pressure regulator & Fuel pressure sensor.


The age of your vehicle also guarantee's a vacuum leak. It may sound silly but the truth is rubber grommets, and hose's shrink and dry out over time and the harsh environment under the hood makes it worse. Check all vacuum lines and fittings attached to the intake manifold, valve covers (pcv valve), and be sure to check for a vacuum fitting on top of the intake just behind the throttle body. Does it fit tight in the hole? You can seal loose fittings with a high-temp RTV (Red) silicone sealant/adhesive. Several small leaks add up and your engine, heat/AC, and transmission will be all to glad to tell you about it.

Aside from that, if you are still having problems, Have a look at the MAP & Oxygen sensors. Finally, you may end up replacing the TBI throttle body assembly.

Car stalls after it warms up and around 4 thousand rpms while driving it also has a little miss after it idles down and you can smell fuel really bad after it starts. have replaced the tps and pcv valve...


i do feel you should have asked a local mechanic to have a look for you first before you spent money on parts ,have you inspected the fuel line for deterioration ,this vehicle is 22 yrs old and has outlived its life so things are wearing out ,including the fuel line rubber hose connections ,while your looking check the rubber pipes on the inlet manifold for deterioration as well ,be surprised what sorts of problems this can cause also the state of the engine breather hoses

Ran out of gas, added gas , engine will not pick up fuel checked relay switch, fuel pump shutoff switch in proper position


The fuel system may need to be primed, (the gas needs to be pulled from the gas tank up to fuel rails. But try to turn your switch on but not start. Leave it on for 1-2 min and try it 4-5 times. This may help with getting the pump to get enough of gas to start pumping.

1995 old acheiva hard to stay running when first starting after it warnup it ok


Hi,
Sounds like no gas is getting to the carb. Or it can be a fuel issue. Bad fuel pump or clogged filter can be the reason, it can be solved by replacing the fuel filter and fuel pump fuse..
Failing EGR or PCV valve. Changing the PCV valve; this can affect starting, especially in cold weather and will allow you to start the car, but then it will die. EGR is similar, but affects more than just starting. The PCV tends to be ok after warm-up.
Everything on a car works together: Simple oil change or air filter change, or fuel filter change make a car start better.
Also there could always be a malfunctioning sensor, you can test this with the help of a mechanic or buy buying an OBDII code-checker at a store.

Let us know if you need further clarification else please accept the solution.
Thanks for contacting fixya.com

2003 ford taurus idle problems had trouble codes


A code P0174 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor. and your solutions are.
    • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner . Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure

Start with the simple fixes first; Try a new fuel filter. Then a new pcv valve. Both are very cheap & you can probably install them yourself.

Locations


The PCV valve should be in the right end of the front valve cover in a rubber grommet
The fuel filter is located in the fuel line underneath the car on the driver's side, infront of the rear wheel.
