    Roll and surge? Its not to bad but I can feel it bump a little when idling and here a small kind of like pop in the exhaust at idle once and a while does this sound like it I had a code that came up sharpshooter purge valve mechanical fault that detected a fuel tank pressure change greater than a minus7inches of h20 with a purge less than.02 lbs per minute have no clue what that means purchased a purge valve still did the same thing

    Purge valve that all for refueling. If its minus 7 you got a leak could be gas cap or the fill pipe. Your cam positioning sensor are famous for problems stall at idle . rough idle weird misfire ect.

    3000 RPM and holding,Let do this remove 02 sensor from both banks and dont disconnect the wire terminal you will get a misfire code if you do.With the 02 out do your test again if it doesnt bog or want to die and it improves the catalytic is plugged.

SOURCE: 2003 Chrysler Town and Country,

If you have issues only at those revs then something is wrong with the O2 sensor - at those revs the air fuel mixture naturally the leanest so maybe at those ratio it reacts abnormally , causing the fuel delivery to be lower than it should so the engine is lacking power. Have the sensor tested.

SOURCE: car was sluggish and now engine light is on van

Hi and welcome to FixYa!

I do suspect that you have a faulty MAF (mass air flow) sensor or bad TPS (throttle position sensor). If the car run sluggish it can be a fault of these two parts. If that's the case it will surely need replacement.

As a first course of action, I strongly suggest that you take the car in to a reputable mechanic and have an engine scan. During the diagnostic it will list the trouble codes and by then you'll know what part needs replacement. It's wiser this way than guessing.

Hope this helps and thank you for using FixYa! Have a good one!

Transmission Question

It sounds to me like the transmission is starting to fail. As the clutches inside the transmission wear the clutch pack gains additional clearance. Your pressures in the transmission will be higher with cold oil so it has a tendency to build a bit of extra pressure, but it's also slower in flowing through the transmission. This results in a harder hitting first gear. As the transmission warms up, it will reduce the viscosity of the oil and work fine. Cold weather kills automatic transmissions. Let it warm up before driving it or it won't last long. It will require an overhaul soon.

97 mustang power loss at 4000 rpm seems like it wants to go but won't doent do it when cold only after runing for about 15 minutes seems like it bogs down

Sounds like a weak fuel pump or clogged fuel filter.Check your fuel pressure it should be 30-45 psi with key on and engine off.

2004 Blazer runs normal cold start, plenty of power. Bogs down after warm up, diminishing power, won't go. Catalytic Converter? What is temp sensitive could bog engine down?

The Catalytic Converter is one possibility, but not likely. If when the truck bogs down, and stalls out, this could be more related to a fuel pump issue. If on your truck the fuel pump is located inside of the fuel tank, then once the pump heats up, this would happen. Acting as though it's something electrical, but it's really not.

2006 chevy 2500 express cargo van .What is a good oil pressure for this van. it has 150,000 miles runs great

60psi cold / 30-45psi warm is ideal. I've seen (with that mileage) 45 cold/ 20 warm and that's acceptable - anything less start thinking about a new oil pump.

93 chevrolet truck bogging down on acceleration

Check intake gaskets. Pour warm soapy water on the gasket when it's running. If it bubbles like crazy, you have a leak. 2. Check timing. Shoot a timing light at the crank mark. If it jumps around a lot, your chain has jumped. #3. check cam. Remove valve covers, run the engine, and see if they are all raisng the valves the same. Put a piece of cardboard along the bottom, and fold it around a little, so it forms kind of a " half valve cover". That way you won't lose oil everywhere, and make a mess, or a fire.
